For the most part, diagnosis has no meaning. The screening must be done to certain groups of persons are predisposed to the development of malignant tumors. It is worth noting that universal marker that detects cancer in the body, does not exist. Moreover, most tumors are extremely difficult to diagnose in the early stages.
There are a number of tumor markers, which have the function of detecting cancer. However, to assign such surveys shall oncologist, and not the man himself. The study makes sense only when the comprehensive examination. It should be remembered that none of the tumor markers does not guarantee the presence or absence of the disease.
"I strongly recommend spending oncoming marker (and especially without a doctor's referral) for the early detection of cancer. The survey for tumor markers will only be offered to patients in whom the results of instrumental examination suspected the presence of tumor pathology in the body (as a clarification of diagnosis), and patients who already have diagnosis of "malignant neoplasm" in history (as prognostic factor for assessing the effectiveness of therapy and monitoring)," comments Maria Pushkareva, oncologist and expert company INVITRO.
