Abnormal tumor markers are substances that are found in the blood, urine, or tissue of a person who has cancer. These markers can be used to diagnose and monitor the progression of cancer, as well as to determine the effectiveness of treatment.
There are many different types of tumor markers, and each type is associated with a particular type of cancer. For example, the prostate-specific antigen (PSA) marker is associated with prostate cancer, while the CA-125 marker is associated with ovarian cancer.
When tumor markers are found in the blood or urine, it does not necessarily mean that a person has cancer. In fact, many people who have high levels of tumor markers do not have cancer at all. However, when tumor markers are found in conjunction with other diagnostic tests, they can be a useful tool in the early detection of cancer.
It is important to note that tumor markers are not foolproof, and they can sometimes give false positive or false negative results. Therefore, they should always be used in conjunction with other diagnostic tests, such as imaging scans and biopsies.
If you have been diagnosed with cancer or are at risk for cancer, your doctor may recommend regular testing for tumor markers. By monitoring your levels of tumor markers over time, your doctor can determine the effectiveness of your treatment and make adjustments as needed.
Ultimately, the presence of abnormal tumor markers is not a death sentence. With early detection and proper treatment, many people are able to overcome cancer and live long, healthy lives.
