Can cancer be detected in blood tests?

Public Comments

1. yes
2. Depends on the type of cancer, the stage of development, etc. Sometimes an X-ray or a ultrasound examination is better. If in doubt, go see a doctor.
3. Some cancers can be detected, but the blood test must be a specific cancer screening - not just "any" blood test.
4. Yes it can. There are two blood tests that can be done to see if in system and also you can have a total body scan done to detect cancer but you may have to pay for that on your own for more of a prevention.
5. no i dont think so but there are certain gens that may cause cancer that they can detects
6. Yes. Certain protiens and an elevated white blood cell count will show, if cancer is present.
7. I had a scare a few years ago and was referred to an oncologist. His first step was a blood test. I guess there's some indicator they look for, but it's been so long now that I don't remember what it is. I don't think it can be diagnosed by just a blood test, but there is definitely something they're looking for.
8. Yes, they can look at your t-cell count and determine whats going on with your body.
9. some kinds
10. A physcian can order a blood test called CA125. If it is suspected that you have cancer this test can aid in a diagnosis, but more tests will be needed for a definite diagnosis.
11. Yes and no. A specific test for specific cancers can be done. If a man is being screened for prostate cancer there a test called the PSA test. That is a specific test for prostate cancer. There is other blood tests that can be done if cancer is suspected but so far there is not one test that can detect all cancers.
12. its an indicator not a diagnosis
13. Yes. They count re and white blood cells in a particular amount.
14. Yes, if someone has a known diagnosis. Some tumor markers are also useful for screening. Again, they are not diagnostic CA 19-9 pancreatic cancer CEA colon cancer, rectal cancer, breast cancer CA 15-5, CA 27-29 breast cancer CA-125 ovarian cancer PSA prostate cancer AFP testicular cancer beta-2 microglobulin lymphoma and multiple myeloma Those are all I can think of off the top of my head. They are useful for screening, and monitoring known disease (i.e., watching if they go up or down in known cancer to detect relapse)
15. Creo que pueden detectar células cancerosas pero no se sabe en dónde...
