The normal value of CA724 is <6.7 μg/L. An elevated value of 47.9 may be related to neoplastic diseases, which are more serious and need to be judged by other tests. CA724 is a tumor marker of gastrointestinal tract and ovary, and the elevation may be caused by ovarian cancer, colorectal cancer, gastric cancer, breast cancer, pancreatic cancer, etc. However, the elevation of this index does not necessarily mean that it is neoplastic disease, and the elevation of CA724 can be seen in benign diseases, such as pneumonia, pancreatitis, rheumatism, benign ovarian cysts, benign ovarian adenomas, and breast diseases. It is recommended to go to the hospital in time, improve the imaging examination and pathology examination and other tumor markers to clarify the cause of the disease, and actively treat it to avoid delaying the condition.
