A tumor marker is anything present in or produced by cancer cells or other cells of the body in response to cancer or certain conditions that provides information about cancer.
These can be found in the blood, urine, stool, tumors, or other tissues or bodily fluids of some patients with cancer. Doctors may use tumor marker tests to learn if you have cancer. These tests can also help doctors to learn more about your cancer and help to plan treatment. If you are also facing any health issues, then you can schedule an appointment for a cancer marker test via https://cbyelitecare.com/.
Tumor marker tests are not perfect. They are often not specific for cancer and may not be sensitive enough to pick up a cancer recurrence. The presence of tumor markers alone is not enough to diagnose cancer. You will probably need other tests to learn more about possible cancer or recurrence. Some limits to tumor marker tests are listed below.
A condition or disease that is not cancer can raise tumor marker levels.
People without cancer can have high tumor marker levels.
Tumor marker levels can change over time. The tests may not get the same result every time.
Tumor marker levels may not go up until cancer gets worse. This does not help find cancer early, or in people at high risk. It also does not help find a recurrence.
You will also need other tests to find cancer and check on treatment. This is because tumor marker results have limitations and are sometimes wrong.
