What does it mean if CA724 is elevated?

CA724 is a tumor marker used to detect malignant tumors such as gastric cancer, liver cancer, lung cancer, and colorectal cancer. It can also be used to monitor tumor metastasis and recurrence. Elevated levels of CA724 indicate increased activity of malignant tumor cells in the body, suggesting the possible presence of a malignancy or that the cancer has already metastasized or recurred. Therefore, when CA724 levels are elevated, further examinations are necessary to determine whether the patient has a malignant tumor and whether the tumor has spread or recurred.
