CEA (carcinoembryonic antigen)<\/strong><\/h3>\nThe main marker for monitoring colorectal cancer. Its increase often indicates the presence of a tumor in the colon or rectum.

CA 19-9<\/strong><\/h3>\nAlthough this marker is more commonly used in pancreatic cancer, it also provides valuable information in colorectal cancer, especially in combination with other markers.<\/p>\n
CA 242<\/strong><\/h3>\nA more specific marker for the intestine.

Often increases in aggressive forms of tumors. Its level is used to monitor treatment.<\/p>\n
mSEPT9 (methylated SEPT9 gene)<\/strong><\/h3>\nAn innovative non-invasive PCR test that detects colorectal cancer from a blood sample. Its sensitivity in early stages makes it a promising screening tool.<\/p>\n
