Now about blood tests for tumor markers they talk a lot and often, you can often hear that they help to detect cancer at an early stage, while there are no symptoms. In fact, this is not the case.
The levels of tumor markers in the blood can increase not only in cancer, but also in other conditions. For example, PSA (prostate-specific antigen) is elevated in cancer and benign prostatic hyperplasia. At the same time, not all cancer patients have elevated levels of tumor markers. Such tests are too unreliable for the primary diagnosis of oncopathologies.
The levels of tumor markers are usually determined in people who have already been diagnosed with a malignant tumor, and are assessed over time. This helps to track the course of the disease, monitor the effectiveness of treatment. If the level of a tumor marker decreases, anticancer therapy helps, and if it increases, drugs are ineffective.
Good afternoon. Indeed, according to tumor markers, one can understand that a tumor is present in the body. The more cancer cells in the human body, the higher will be the indicators of tumor markers. But at the same time, tumor markers are present in a healthy body, and just when tumors appear, they grow rapidly.
From the above, it is clear that when donating blood for tumor markers, it is possible to reveal the presence of cancer, as well as the localization of the tumor. Including, it is possible to detect cancer at an early stage. But you need to understand that all the same, this is not a 100% indicator of the presence of a tumor, since they can grow with other diseases. Therefore, it is extremely important to take into account the results of not only one analysis, but also other types of research, which the doctor will decipher.
