Tumor marker test results are available in 1-2 days. Tumor marker testing is not a special examination; it is generally performed through a blood test. Results are usually available on the same day or the following day. However, if the hospital lacks the testing equipment and the sample needs to be sent to another hospital, results may take up to a week.
Tumor markers reflect the process of tumor formation and proliferation in the body. They are chemical substances associated with tumors, and their presence or quantitative changes can indicate the nature of the tumor, helping to understand tumor histogenesis, cell differentiation, and cell function, thus aiding in tumor diagnosis, classification, prognosis, and treatment guidance.
Abnormal tumor marker test results generally indicate elevated levels of the marker antigen, clinically manifesting as the presence of malignant or benign tumors or cancer. A positive result indicates hepatocellular carcinoma, gastric cancer, liver cancer, pancreatic cancer, colorectal cancer, etc.
It is generally recommended that elderly people undergo regular checkups. For cancer prevention, a regular diet rich in fresh foods is important; avoid fried, grilled, pickled, and smoked foods.
