tumormarkerek

Tumormarkerek, also known as tumor markers or biomarkers, are substances produced by cells that can be detected in the blood, urine, or other bodily fluids. They are used to detect, monitor, and manage cancer. Tumormarkerek can be categorized into two types: tumor-specific markers and non-tumor-specific markers. Tumor-specific markers are produced by cancer cells and are unique to certain types of cancer, such as prostate-specific antigen (PSA) for prostate cancer. Non-tumor-specific markers, like carcinoembryonic antigen (CEA), can be produced by both cancer cells and normal cells, making them less specific but still useful in some cases. Tumormarkerek are measured using blood tests and are often used in conjunction with imaging tests and biopsies to diagnose and stage cancer. They can also help monitor the effectiveness of treatment and detect recurrence. However, it's important to note that tumormarkerek are not foolproof and can sometimes produce false positives or negatives. They should be interpreted by healthcare professionals in the context of the individual's overall health and other test results.
