Patient's question:
Initial examination revealed pelvic cancer with poorly differentiated cancer cells. After removal, no recurrence was found, but the doctor recommended chemotherapy to prevent recurrence. I want to ask if chemotherapy is necessary, and can pelvic cancer be detected through blood tests?Doctor's answer:
Blood tests can detect cancer. Blood tests can be used to screen for cancer, but they are only for reference and do not necessarily mean that you have cancer if the blood test results are abnormal. There are many types of tumor markers that can be detected through blood tests, and each represents a different meaning. The tests for tumors in different parts of the body are also different. Blood tests are specifically targeted at certain types of cancer, with the most important being the detection of chemical substances that act as tumor markers. These substances are produced by different types of tumors. Therefore, the tumor markers for tumors in different parts of the body are different.
