Which all are the Cancer Blood Test?

Last updated on September 9th, 2022 at 07:38 am

Cancer blood tests and other lab tests, including tissue analysis, urinalysis and tumor markers, are used to diagnose and treat cancer.

What blood test are done for cancer?

Cancer Blood tests look for cancer markers, sometimes called cancer markers, in the blood, urine, or body tissues. Cancer markers are substances made by cancer cells or by normal cells in response to cancer in the body. Some cancer markers are specific to one type of cancer. Others can be found in several types of cancers.

Because cancer markers can also show up in certain noncancerous conditions, cancer marker tests are not usually used to diagnose cancer or screen people at low risk of the disease. These tests are most often done on people already diagnosed with cancer. Cancer markers can help find out if your cancer has spread, whether your treatment is working, or if your cancer has come back after you’ve finished treatment.

Would blood test detect cancer?

Cancer blood tests are most often used to;

  • Plan your treatment. If cancer marker levels go down, it usually means the treatment is working.
  • Help find out if cancer has spread to other tissues
  • Help predict the likely outcome or course of your disease
  • Check to see if your cancer has come back after successful treatment
  • Screen people are at high risk for cancer. Risk factors can include family history and previous diagnosis of another type of cancer.

What blood test shows up with cancer?

You may need a cancer marker test if you are currently being treated for cancer, have finished cancer treatment, or have a high risk of getting cancer because of family history or other reasons.

The type of test you get will depend on your health, health history, and symptoms you may have. 

Below are some of the most common types of cancer markers and what they are used for;

CA 125 (cancer antigen 125)

What blood test show cancer?

There are different ways to test for cancer markers. Blood tests are the most common type of cancer marker tests. Urine tests or biopsies may also check for cancer markers. A biopsy is a minor procedure that involves removing a small piece of tissue for testing.

  • If you are getting a blood test, your lab technician will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
  • If you are getting a urine test, a lab technician for instructions on how to provide your sample.
  • If you are getting a biopsy, a doctor will take out a small piece of tissue by cutting or scraping the skin. If your provider needs to test tissue from inside your body, he or she may use a special needle to withdraw the sample.

Depending on what type of test you had and how it was used, your results may:

  • Help diagnose the type or stage of your cancer.
  • Show whether your cancer treatment is working.
  • Help plan future treatment.
  • Show if your cancer has returned after you’ve finished treatment.

If you have questions about your results, talk to your doctor or laboratory manager.

Are there any risks to the cancer blood test?

There is a minor risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly. There is no risk to a urine test. If you have had a biopsy, you may have a little bruising or bleeding at the biopsy site. You may also have a minor discomfort at the site for a day or two.

Any special preparations required for cancer blood test?

You rarely need any special preparations for a blood or urine test. If you are getting a biopsy, you may need to fast (not eat or drink) for several hours before the procedure. Talk to your health care provider if you have questions about preparing for your test.

Cancer blood test limitations

Cancer markers can be very useful, but the information they provide can be limited because:

  • Some noncancerous conditions can cause cancer markers.
  • Some people with cancer don’t have cancer markers.
  • Few cancer has cancer markers.

So, cancer markers are almost always used with other tests to help diagnose and monitor cancer.
