What is a common method to assess the response to chemotherapy?

Imaging studies such as CT scans or MRIs are commonly used to assess the response to chemotherapy because they provide detailed visualizations of the size and extent of tumors. These imaging techniques allow healthcare providers to compare the current state of the tumor with previous images taken before treatment began, helping to determine whether the chemotherapy is effective in shrinking or eliminating the cancer. Additionally, imaging studies can reveal the presence of any new tumors or disease progression, thereby giving a comprehensive view of the cancer's status.

Physical examinations can provide immediate feedback on a patient’s overall health and symptoms but may not capture detailed changes in tumor size or response as effectively as imaging studies. Blood tests can indicate certain biomarkers or tumor markers but often lack the specificity needed to assess tumor response accurately. Patient self-reports can provide valuable insights into symptoms and the quality of life, but they do not replace the objective measurements needed to evaluate changes in tumor burden accurately. Overall, imaging studies are the standard method for assessing the response to chemotherapy due to their precision and ability to visualize structural changes in the body.
