Blood test detection of cancer is not the best way to go but it is important to determine what you are actually concerned about. Depending on your age , family history and specific symptoms you may have there are more specific ways to look for cancer . Sometimes we can worry ourselves in to a bad situation thinking that we are going to get cancer. It is helpful to talk to a general doctor about what cancer you are trying to detect.

Remember blood test alone can’t able to detect cancer; there are several other tests, which patient’s have to endure for cancer’s detection. However, blood test is obviously the first step that gives doctor some clues about what's going on in your body. Patients have to face other tests such as urine analysis or a biopsy of a suspicious area performed in the laboratory by tools present at that helps in diagnosing the disease. Examples of some blood tests are CBC, blood protein testing and tumor marker tests.
