What role do tumor markers play in monitoring treatment response?

• A. They help predict the likelihood of cancer recurrence
• B. They assess if treatment is effective by measuring specific substances in the blood
• C. They determine the appropriate dosages for chemotherapy drugs
• D. They indicate the need for surgical intervention

Answer: (B)

Tumor markers serve as key indicators in monitoring treatment response by providing a measurable assessment of specific substances that are often released into the bloodstream by cancer cells. When a patient is undergoing treatment, the levels of these markers can fluctuate based on the effectiveness of the therapy being administered. A decrease in tumor marker levels typically suggests that the treatment is effective, while stable or rising levels may indicate that the cancer is not responding to therapy or is progressing. The use of tumor markers allows healthcare providers to make informed decisions about continuing, adjusting, or changing treatment strategies based on real-time data regarding how the cancer is responding. This monitoring is crucial in personalizing treatment plans and improving patient outcomes.
