Fecal occult blood test (TSOH)-a stool sample is examined to identify traces of blood that are invisible to the naked eye. If the test result is positive, the study is completed with a colonoscopy to visualize the origin of the bleeding. If blood is seen in the stool, it is important to contact your doctor immediately.
Colonoscopy: Colonoscopy is a painless test performed with sedation at MD Anderson Madrid. It consists of examining the mucous membrane of the colon using a colonoscope. The process involves a previous preparation based on the cleaning of faeces from the intestinal tract to be explored. The colonoscopy lasts between 20 and 30 minutes, during which biopsies can be taken or polyps resected.
Colon polyps are protrusions on the mucosal surface of the colon, usually slow-growing. Not all polyps will necessarily lead to colon cancer, although the vast majority of malignant tumors have a polyp as their precursor. Colonoscopy allows the same test to detect and eliminate these lesions to prevent the appearance of colon cancer or treat it early.
