High cancer antigen CA724 can be seen in malignant tumors such as ovarian cancer and colorectal cancer, as well as benign diseases such as pancreatitis and liver cirrhosis. Carcinoma antigen 724, or CA724, is a tumor-associated glycoprotein, which can be used for the auxiliary diagnosis of tumors, and is a tumor marker for the gastrointestinal tract and ovary. Elevated CA724 can be seen in 67% of patients with ovarian cancer, 47% of patients with colorectal cancer, 45% of patients with gastric cancer, 40% of patients with breast cancer and so on. However, elevated CA724 can also be seen in a small number of normal people and patients with benign gastrointestinal diseases, such as pancreatitis, cirrhosis of the liver, as well as benign ovarian diseases and benign gynecological diseases. Generally, CA724 will be tested in combination with cancer antigen 125 (CA125) and carcinoembryonic antigen (CEA), etc. It is recommended that patients consult with their specialists and make comprehensive judgment by combining with the results of other tumor markers, imaging and pathology.
