The objective of this article is to review the effectiveness of data analysis models such as the logistic regression model and the CHAID decision tree model in diagnosing this type of cancer using various ultrasound imaging techniques. In this article, we will examine how data was collected from a study involving 203 patients, in addition to comparing the efficiency of the models used in identifying malignant tumors and extracting their key characteristics. We invite you to discover how these models contribute to enhancing the accuracy of thyroid cancer diagnosis and providing new insights for treating this common health condition.
Effectiveness of Statistical Models in Diagnosing Papillary Thyroid Cancer
The rising incidence of papillary thyroid cancer (PTC) reflects the importance of developing effective diagnostic strategies. The logistic regression model and the CHAID decision tree were adopted as analytical approaches to compare the diagnostic effectiveness of these factors using various ultrasound imaging techniques. The study indicates that statistical approaches can contribute to enhancing the accuracy of detecting papillary thyroid cancer and preventing delayed diagnoses.
In a prospective study involving 203 patients, a wide range of clinical features was assessed, such as nodule shape, blood flow pattern, and tissue stiffness measured through techniques such as Shear Wave Elastography (SWE) and Contrast-Enhanced Ultrasound (CEUS). It was clear that indicator factors such as the correlation between echogenicity, the length-to-width ratio, and the potential presence of microcalcifications play a significant role in identifying suspected malignant cases.
The results showed that the selected models not only provided similar diagnostic capability but also equipped physicians with valuable insights on how to utilize the technology in clinical diagnosis. Overall, this demonstrates that statistical applications in the context of medical imaging represent a positive step towards improving the quality of healthcare.
Diagnostic Strategies for Thyroid Cancer Using Ultrasound Imaging
Given the thyroid gland’s nature as a tissue amenable to ultrasound examination, early diagnosis of tumors is crucial. Available techniques such as conventional ultrasound, Shear Wave Elastography (SWE), and Contrast-Enhanced Ultrasound (CEUS) illustrate how studies can effectively rely on these methods.
Conventional ultrasound allows physicians to examine the general characteristics of the thyroid gland, such as shape, size, and the effect of nodule fluid. Meanwhile, SWE provides additional information regarding tissue stiffness, aiding in differentiating between healthy and affected tissues. This step is central, as tissue stiffness is often associated with the severity of the condition. CEUS, on the other hand, offers additional insights into the tissue’s interaction with contrast agents, making it a valuable tool for improving diagnostic accuracy.

Among the most prominent issues is the false negative rate that can be associated with fine needle aspiration biopsy (FNAB). Inaccurate results can arise if there is a needle sampling impediment or if the nodule is too small. This obstacle represents one of the most significant issues that physicians and practitioners strive to improve through accurate diagnostic models.
Moreover,
On that note, doctors need to make decisions based on a comprehensive analysis of clinical information and ultrasound data, which may increase the burden on the modern medical system. The excessive use of cases requiring additional tests such as biopsies can strain hospital resources and increase patient anxiety. Therefore, there remains an urgent need to create more modern models that integrate both diagnostic information with imaging to reduce the rate of misdiagnosis and facilitate decision-making.
However, these challenges can be avoided through the development of models such as logistic regression and the CHAID decision tree that incorporate comprehensive data. These models, which represent a step towards improving medical understanding, could play a vital role in providing accurate information and helping us distinguish between benign and malignant tumors more effectively.
Future Trends in Thyroid Tumor Imaging
Technological advancements carry with them a desire to improve healthcare, especially in the field of tumor imaging. Ongoing research for new and innovative methods to achieve more accurate diagnoses and provide better care is an urgent necessity for the health system. It is expected that ultrasound imaging technologies will play a central role in the future diagnosis of thyroid disorders.
Detailed research continues to improve various medical imaging techniques, specifically in how to integrate available data from different technologies.

Tools and Methods Used in Medical Examinations
Medical examinations used to diagnose thyroid nodules are characterized by precision and technological advancement. The HOLOGIC Aixplorer ultrasound device has been used, which excels due to its SL15-4 probe, transmitting ultrasound waves at frequencies ranging from 4 to 15 megahertz. This device has been employed in imaging and assessing nodules, where the entire thyroid gland, including the lobes and isthmus, is imaged to determine nodule characteristics according to the TI-RADS criteria set by the American College of Radiology. These characteristics include dimensions and morphological features, such as the length-to-width ratio, clarity of borders, and type of stiffness.
Traditional ultrasound imaging is performed where the patient is asked to lie in an appropriate position to obtain the best view of the thyroid gland. Through this examination, nodules are classified based on size and shape using modern techniques such as contrast-enhanced ultrasound (CEUS) where a dye is administered during the examination to clarify blood flow within the nodules. This helps in determining whether the nodule is benign or malignant.
Modern techniques such as ultrasound elastography (SWE) are also employed, where the stiffness of the thyroid nodules is measured, providing important data that assists doctors in reaching an accurate diagnosis. This is followed by making treatment decisions based on the results, including the need for a thyroid biopsy.
Traditional Ultrasound Imaging and Contrast-Enhanced Imaging
Traditional ultrasound imaging represents a vital tool in diagnosing and monitoring thyroid health. During this process, sound energy is directed at the targeted area, facilitating a clear image of the nodules. The patient is placed in a suitable position to provide the best view, thereby allowing nodules to be evaluated based on multiple criteria such as shape, size, and structure.
When
Using Contrast Enhanced Ultrasound (CEUS) techniques, a special dye is injected to enhance the visibility and assess blood flow in nodules. This allows doctors to distinguish between malignant and benign nodules by monitoring the blood flow pattern. For example, nodules that show unbalanced blood flow may indicate a higher risk of transforming into cancer.
The degree of enhancement is evaluated, such as irregular or central enhancement, as well as the arrival time of the imaging dye by measuring the contrast present in the nodule compared to the surrounding cells. This process requires high expertise from the supervising doctors and studies have shown that using various imaging techniques can significantly improve diagnostic accuracy.
Biopsy Techniques and Statistical Diagnosis
A biopsy is considered the next step to confirm the diagnosis when initial examination results indicate the possibility of a malignant tumor. The biopsy is performed by inserting a fine needle under ultrasound supervision, ensuring an accurate sample is taken from the targeted nodule. This process must be conducted carefully to ensure that the patient receives adequate anesthesia and feels comfortable.
After the sample is taken, it is transferred to the laboratory for histological analysis. This analysis shows potential cellular changes and confirms whether the nodule is malignant or benign. Various statistical models and tools may be used to evaluate the data extracted from nodule biopsies, such as logistic regression models to analyze risk factors and predictions.
SPSS is considered one of the tools used in statistical analysis, where data is analyzed using various criteria such as the T-test for normally distributed data and the Mann-Whitney test for non-normally distributed data. This analysis helps doctors identify independent factors associated with thyroid nodules and consider future treatment developments.
Research Findings and Predictive Modeling
The examination results showed that out of 203 thyroid nodules, 111 represented papillary thyroid carcinoma (PTC). Various techniques were used to identify the characteristics that distinguish these nodules, such as Emax and Emin measurements, which showed significant statistical differences. Malignant nodules generally exhibited higher stiffness. These measurements pertain to tissue stiffness and significantly affect diagnosis, thus benefiting treatment options.
By using the CHAID DT model, accurate predictions were built based on the analyses conducted. It was shown through modeling that many statistical criteria could have a significant impact on the nodule’s malignancy likelihood. This clearly indicates the need for broader studies to confirm the precise factors that contribute to determining future treatment outcomes.
In conclusion, it can be said that combining various imaging techniques with statistical analysis provides surgeons and physicians with valuable tools to facilitate decision-making and thus improve clinical outcomes for patients.
Comparing Acoustic Features Between PTC and Non-PTC Groups
When it comes to diagnosing follicular thyroid tumors, or what is known as PTC, multiple acoustic techniques are considered important tools used. A comprehensive comparison of the number of standard ultrasound acoustic features between the PTC group and the non-PTC group was conducted. This analysis revealed significant differences between the two groups, indicating the role of acoustic features as critical factors in diagnosis. Examples of the acoustic features analyzed include nodule characteristics such as echogenicity, aspect ratio, nodule shape, hypoechogenicity, and maximum stress value. Through this analysis, a matrix of independent statistically significant factors was identified, helping doctors make diagnostic decisions based on accurate and scientific results.
Development of Logistic Regression Models and Result Analysis
A logistic regression model was created based on the multi-modal acoustic features to determine the likelihood of PTC. Independent factors that showed statistically significant differences were included in the model, allowing the opportunity to predict the presence of thyroid tumors based on acoustic characteristics. It is important to note that the model’s accuracy was 81.3%, suggesting that the use of acoustic features can enhance doctors’ ability to diagnose PTC more quickly and efficiently. In this model, the most influential factors in determining the presence of PTC were echogenicity, hypoechogenicity status, and aspect ratio, highlighting the importance of these features as key factors for diagnostic analysis.
Model
CHAID DT and Predicting the Presence of PTC
The CHAID DT model was built to predict PTC based on certain acoustic features that are statistically significant. The root of the node in the model represents the maximum stress, indicating that it is the most influential factor in the presence of PTC. By applying cross-validation, this model achieved a diagnostic accuracy of 82.4%, indicating that it provides another powerful tool to assist doctors in diagnosis. This model enables predictions to be made non-invasively, which is notable in facilitating the diagnostic process and healthcare for patients.
ROC Curve Analysis for Logistic Regression Models and CHAID DT Model
The ROC curves for both models, logistic and CHAID DT, were studied and analyzed, revealing that both have a high AUC index, reaching 0.878 and 0.883, respectively. These values indicate the effectiveness of both models in predicting PTC. When using 52.48% as the minimum predictive value, both models showed high sensitivity and specificity, reinforcing their potential use as effective diagnostic criteria. These results enhance the discussion around medical technology and its applications in providing accurate and rapid diagnostic information.
Discussion on the Results and Future Developments
Despite the need to make some reservations about FNA techniques, the results demonstrate the importance of using ultrasound, thus encouraging further research in this area. Modern ultrasound technology, including ultrasound enhancement and multiple patterns, has become a focal point in clinical contexts. Enhancing these techniques, in addition to data analyses, is seen as a potential future to support physicians and will not only improve diagnostic accuracy but also provide continuous monitoring of medical cases. Developing stronger models and expanding the scope of these techniques could enable predicting other risks, providing personalized medical solutions that enhance the evolution of healthcare more efficiently.
The Impact of Vascular Distribution on Tumor Enhancements
Studies have shown that vascular effects are unevenly distributed among cancer cells, leading to recent cases such as increased central enhancement in 56 out of 111 cases of papillary thyroid carcinoma (PTC) during examination. This is attributed to a decrease in the number of central blood vessels compared to peripheral vessels, which are more dense. This phenomenon is particularly evident in malignant nodules, where intratumoral blood vessels are sparse, leading to low enhancement. Among 66 malignant nodules examined, the results showed low enhancement, which may indicate damage to new blood vessels or impaired function due to fiber density in tumor cells.
This uneven distribution is closely related to the tumor’s formative nature, as nodule growth affects tumor oxygenation. For example, studies have shown that nodules with a diameter of up to 1 cm, whether malignant or benign, typically show equal or high enhancement due to blood accumulation within the nodule during the growth phase. This makes accurate and positive assessment through traditional examinations, such as ultrasound, essential for our understanding of how to differentiate between benign and malignant lesions.
The Role of Implementing Multiple Screening Techniques in Diagnosing Thyroid Cancer
Results from multifactorial analysis suggest that the characteristics observed using Contrast-Enhanced Ultrasound (CEUS) could not serve as an independent risk factor for diagnosing thyroid cancer. Nonetheless, strategies such as logistic regression models and the CHAID decision tree model appear promising. The CHAID model demonstrates that the distribution of the contrast agent and the timing of its perfusion play significant roles in diagnosis. This indicates the importance of implementing multifactorial analysis, where CEUS is not a sufficient standalone diagnostic tool but needs to be integrated with traditional screening techniques.
Being used
Technologies, such as traditional ultrasound waves, along with the flexibility of acoustic waves (SWE) and CEUS, enhance diagnostic accuracy. For instance, a system was developed to determine the grades of thyroid nodules using these multiple methods, and studies have shown that they represent a significant advancement in the early diagnosis of tumors. It is clear that with the evolution of multiple imaging technologies, clinical efficiencies can be greatly improved, providing a broader spectrum of information for case analysis.
Current Challenges in Diagnosing Thyroid Cancer via Ultrasound
The uses of ultrasound come with several limitations that significantly affect diagnostic accuracy. One of the major challenges is the difficulty in distinguishing between benign and malignant tumors due to the similarity in imaging patterns in cases such as Hashimoto’s thyroiditis, where the clinical presentation resembles cancerous tumors. This can lead to misdiagnosis, highlighting the need for more accurate and adaptive examinations.
On the other hand, traditional CDFI techniques hinder the ability to recognize small blood vessels in low-speed flows. If the new blood vessels are not fully mature, the blood signals may be insufficient to confirm a cancer diagnosis, necessitating the collaboration of multiple monitoring efforts, such as the study using SWE, which provides us with a color map of the feature values.
Improving the methods used to measure density in relation to the size and capacity of the defect is also essential. Small tumors have low enhancement that may be due to improperly available blood vessels, while larger tumors may show a trend toward better responsiveness in examinations, requiring in-depth analysis.
Assessing the Effectiveness of Diagnostic Models Used in Studying Thyroid Cancer
Results from statistical analysis indicate that the effectiveness of the models used in diagnosis, such as logistic regression and decision tree models, emphasizes their high efficiency in providing accurate diagnoses. It is evident that both models exhibit potentially similar performance in diagnosing thyroid cancer, reflecting the possibility of using either based on the requirements of the case and its complexity.
The advantages of the logistic model lie in analyzing the assumptions between dependent and independent variables, enabling an understanding of the impact of each variable in the context of holding other variables constant. In contrast, the CHAID model highlights distinctive interactions between variables in a simple and visual manner, facilitating the comprehension of inferential distribution. However, both models collaborate to enhance multiple screening methods, leading to improved accuracy of malignant tumor estimations.
Management of Thyroid Nodules
The importance of managing thyroid nodules is increasing as a vital subject in modern medicine, where the early and accurate detection of these nodules is a key factor in the success of treatment and prevention of complications. Effective management of thyroid nodules involves assessing the risk of cancer and providing appropriate treatment options. Imaging techniques such as ultrasound play a pivotal role in detecting thyroid nodules, allowing for the identification of the morphological features of the nodules. The assessment of thyroid nodules is divided into several levels, from simple clinical examinations to advanced tests such as needle biopsy. One of the main challenges is balancing the need for cancer detection and avoiding excessive examinations that can lead to unnecessary anxiety for patients.
According to the strategy for managing nodules, individuals who show thyroid nodules on ultrasound examination should be evaluated based on multiple factors including nodule size, presence of symptoms, and acoustic characteristics. Nodule size is one of the most prominent factors, with threshold points established for nodule sizes to classify them as at risk for cancer.
Separate studies have shown that using ultrasound techniques such as enhanced and multidimensional ultrasound helps improve diagnostic accuracy. Information derived from advanced examinations provides a higher capability to differentiate between benign and malignant nodules, enabling healthcare teams to make informed decisions regarding treatment. For example, special techniques such as Elastography may be used to estimate the stiffness of the nodule, assisting in assessing its risk.
Techniques
Advanced Imaging in Thyroid Cancer Diagnosis
The development process in diagnosing thyroid cancer requires the use of advanced imaging techniques, with ultrasound and contrast differentiation being commonly used innovative methods. Ultrasound is utilized to assess several specific characteristics of thyroid nodules such as shape, margins, and texture. Based on these characteristics, specialists can deduce the likelihood of a nodule being malignant.
Based on numerous studies, a classification system called “TI-RADS” has been adopted, which includes specific criteria that help classify thyroid nodules based on potential cancer risks. The system relies on imaging of nodules and analysis of their acoustic properties. For example, nodules with irregular margins or thickened circumferences are considered more likely to be cancerous according to this system.
Additionally, there has been notable advancement in the use of enhanced ultrasound technology, which allows doctors to see fine details during thyroid examinations. The effectiveness of this technique lies in its ability to provide additional information about blood flow within nodules, which can be a strong indicator of the potential presence of a malignant tumor. For instance, if a nodule shows an abnormal blood flow pattern, this may elevate the risk of cancer.
In the applied examination, needle biopsy is an effective technique for obtaining tissue samples for microscopic analysis. However, the accuracy of biopsies depends on the skill of the doctor and the technique used, so it is important that they are performed by physicians with expertise in this field. Ultimately, the use of these modern techniques contributes to determining the health of thyroid nodules and ensuring effective patient management, leading to improved treatment outcomes and elevated levels of overall healthcare.

These methods contribute to the development of accurate diagnostic strategies. For example, ultrasound provides valuable information about the shape and size of nodules, in addition to the presence or absence of signs such as calcification. This information provides a strong basis for clinical decision-making. It is important that clinical results be examined carefully to avoid misdiagnoses, which requires the use of multiple diagnostic tools simultaneously.
Statistical Model for Data Analysis
In this context, multiple statistical models have been developed, the most prominent of which are the logistic regression model and the CHAID decision tree model to apply to data on nodule characteristics. Variables such as echogenicity, aspect ratio, presence of calcifications, and other characteristics of the nodules have been included to determine whether they are malignant or benign. Studies show that using these models can facilitate early diagnosis and improve predictive accuracy. For example, the logistic model demonstrated a high accuracy rate of 81.3% in determining the nature of nodules, reinforcing the importance of these models in enhancing clinical outcomes for patients.
Analysis of Additional Results
Researchers have addressed the importance of various clinical examinations, such as blood flow pattern assessment, in diagnosing thyroid cancer. The examinations conducted regarding blood flow did not provide clear signals when distinguishing between malignant and benign tumors, raising questions about their effectiveness. However, other techniques such as stiffness assessment using ultrasound elastography have shown promising results in classifying tumors. The use of a variety of screening techniques may help avoid cases of misdiagnosis, thereby improving the quality of healthcare provided to patients.

The application of statistical models and technology in screening provides doctors with multiple tools to deliver better care, but individual factors for each patient should always be considered to achieve the best possible results.
Modern Techniques in Diagnosing Thyroid Cancer Cells
In recent years, new imaging techniques have been introduced aimed at improving the diagnosis of thyroid cancerous tumors, such as contrast-enhanced ultrasound (CEUS) and shear wave elastography (SWE). These techniques play an important role in differentiating between benign and malignant tumors. For instance, studies conducted by Lei Zhu and colleagues showed that real-time elastography (RTE) in conjunction with fine-needle aspiration achieved exciting results, with the area under the ROC curve being 0.78 and 0.89 respectively. However, SWE was more specific than RTE, indicating its accuracy in determining tumor type.
Aiming to
These technologies aim to overcome the shortcomings of traditional ultrasound imaging, which may fail to distinguish between malignant and benign tumors, especially in complex cases like Hashimoto’s thyroiditis. In many instances, the presence of inflamed tissue can result in images that resemble cancerous masses, making misdiagnosis easier.
The new standards introduced include the combined use of several techniques to provide an accurate diagnosis, as studies have shown that integrating CEUS with techniques such as SWE can enhance diagnostic effectiveness. For instance, a model for evaluating tumors in patients based on traditional ultrasound imaging has been developed, which has shown accurate results in detecting cancerous tumors. However, each technique carries some limitations, such as the limited capability of CEUS in cases of small tumors that may not show any signs indicating the presence of cancerous cells.
Clinical features of cancerous tumors in the thyroid
When studying tumors like thyroid cancer, it is noted that many screening tactics rely on the characteristics of the affected tissue. For example, researchers have combined various imaging features such as density and color change in SWE to analyze stiffness. Some suggest that tumors exceeding 1 cm in size tend to show low to moderate enhancement due to increased blood flow. In contrast, in cases of tumors larger than 2 cm, they often display high enhancement, making them susceptible to early detection.
Advanced research focuses on abnormal features such as microcalcifications and uneven vascular distribution. In some studies, it has been found that 66% of cancerous tumors exhibit low enhancement, which may result from vascular damage or tissue fibrosis. This occurs due to internal architectural changes that affect blood flow and vessel distribution, thereby presenting these tumors in images that may appear benign but represent a serious medical condition. The need for greater accuracy in imaging emphasizes the necessity of integrating multiple techniques to improve diagnostic outcomes.
When dealing with tumors, it is also essential to observe blood flow in the affected tumors. Research indicates that new cancerous tissues may not possess adequate blood flow, making the determination of the condition more complex. For instance, some tumors may not show clear blood flow during CEUS testing, which needs to be considered carefully, as it can lead to misleading results.
Statistical analysis model for cancer diagnosis
In an effort to enhance diagnostic means, several analytical models have been developed, such as the logistic regression model and the CHAID decision tree model. Survey studies have shown that both models provided good diagnostic results, with each having a comparable ability to identify cancerous tumors. The logistic regression model analyzes the interrelationships between independent and dependent variables, providing detailed insight into how various factors influence diagnostic outcomes. Meanwhile, the CHAID model relies on event probabilities and offers a straightforward visual representation reflecting the interaction of variables.
Reports indicate that further research is needed to support data and clinical observations. In many cases, the impact of noise and lack of data in models like CHAID may pose challenges in interpretation. This necessitates more extensive studies to ensure reliability and trustworthiness in applying these models. Despite the obstacles, these models have achieved significant value in aiding physicians in making informed decisions regarding patients’ health conditions, in addition to fostering collaboration among various medical departments.
It is worth mentioning that continuous communication between doctors and researchers must continue to improve in the fields of education and technology to ensure the best outcomes for the diagnosis and treatment of cancer tumors. A new vision on how to use data extracted from modern imaging can lead to constantly evolving therapeutic strategies and will enhance the quality of general healthcare.
Thyroid Problems and the Importance of Early Detection
The thyroid gland is considered one of the important glands in the body, playing a vital role in regulating metabolic processes and energy. Among the common health issues faced by this gland are the presence of persistent nodules or lumps. Studies indicate that the prevalence of thyroid nodules can reach 50% of the population in some countries, making it one of the cases that require careful medical follow-up. The importance of early detection relies on the ability to determine whether these nodules are benign or malignant, which significantly impacts treatment plans and potential outcomes for the patient.
Early detection methods include a range of clinical examinations, including physical examination, where the doctor examines the neck area for any changes in the size of the thyroid gland. Imaging techniques such as ultrasound are also used, providing vital information about the shape and size of the nodules. Microscopic examinations are used as a subsequent procedure to confirm the nature of the nodule, helping to alleviate potential concerns regarding cancer.
Surgical procedures and treatment modifications are very important in the advanced stages of the disease; therefore, regular check-ups and monitoring are considered essential tools to prevent the exacerbation of the condition. For instance, radiation or drug therapy can significantly reduce the size of the nodules in cases diagnosed early.
Modern Imaging and Diagnostic Techniques
In recent years, imaging techniques have significantly advanced, making the detection of diseases associated with the thyroid gland more accurate and effective. Among these techniques is ultrasound imaging. This type of imaging provides clear images of the nodules and helps to accurately determine their characteristics, which include size, shape, and internal composition. Furthermore, it has become possible to use contrast-enhanced ultrasound, a procedure that allows for the visualization of blood flow to the nodule, aiding in determining whether it is malignant or benign.
Multifaceted sound markers are considered one of the most important innovations in this field. Studies have demonstrated the effectiveness of using clinical risk assessment systems to ensure patient safety. By using modern techniques such as “elastography,” the stiffness of nodules and other significant information related to tissue quality can be evaluated, leading to more accurate results in predicting the possibility of nodules transforming into cancer.
Experts recommend integrating imaging technology into the TI-RADS system, which serves as a standard reference for assessing thyroid nodules. Based on the established specifications, the nodules are classified according to the level of suspicion for malignancy, enabling doctors to determine appropriate therapeutic programs. For example, nodules classified as TI-RADS 4 begin with additional procedures such as biopsy tests to determine the optimal type of treatment.
Treatment Strategies and Surgical Intervention
Based on the results of the diagnostic evaluation, an appropriate treatment strategy for thyroid nodules is determined. In cases confirmed to be benign, interventions can be limited to regular monitoring without the need for any surgical procedures. However, if it is determined that the nodule is malignant, surgical operations are planned to remove the cancerous tissue. Total or partial thyroidectomy is one of the common options in such cases.
Surgical resection is the most common option for cancerous nodules, as it involves the complete removal of the cancerous tissue, reducing the chances of cancer spreading to other parts of the body. Radiation therapy is sometimes used to treat advanced cancer, especially when surgery is not feasible. At the same time, drugs that target cancer cells are integrated into some treatment programs to enhance outcomes.
Including
The treatment strategy also includes providing psychological support for patients, as a cancer diagnosis can have significant psychological effects. Providing clear and helpful information about procedures is essential to be part of the treatment plan. Follow-up breast plans are also recommended to improve monitoring any new changes that may occur after treatment, therefore continuous communication with specialized doctors in this field is necessary.
