The reason for the elevated FC levels in CRC is not fully understood. It is thought that the cancer cells may release FC, or that the inflammation caused by the cancer may lead to increased levels of FC in the stool.

faecal calprotectin levels in cancer can be used as a marker for inflammation in the colon. In people with IBD, FC levels are typically very high. In people with CRC, FC levels are often elevated, but they can be normal in some cases.

A high FC level can be a sign of CRC, but it is not a definitive diagnosis. Other conditions that can cause elevated FC levels include IBD, inflammatory bowel infections, and celiac disease.

If you have a high FC level, your doctor may recommend further testing, such as a colonoscopy, to rule out CRC or other serious conditions.

Here are some additional facts about faecal calprotectin levels in cancer:

FC levels can be used to screen for CRC in people who are at high risk for the disease.

FC levels can be used to monitor the response to treatment for CRC.

FC levels can be used to predict the risk of recurrence of CRC after treatment.

Faecal calprotectin is a promising biomarker for CRC, but it is not yet a perfect test. More research is needed to improve the accuracy of FC testing for CRC.
