Colorectal cancer is the third leading cause of cancer-related deaths in the United States. Screening for colorectal cancer is important for early detection and treatment. One way to screen for colorectal cancer is to look for signs of blood in the stool. Blood in the stool can be a sign of colorectal cancer, but it can also be caused by other conditions, such as hemorrhoids or anal fissures. It is important to see a doctor if you notice any blood in your stool, especially if you are over the age of 50 or have other risk factors for colorectal cancer.
There are a number of different ways to screen for colorectal cancer. One common method is a colonoscopy. A colonoscopy is a procedure in which a thin, flexible tube is inserted into the rectum and colon to look for polyps or other abnormalities. Another common screening method is a sigmoidoscopy. A sigmoidoscopy is a procedure in which a thin, flexible tube is inserted into the rectum and sigmoid colon to look for polyps or other abnormalities. Both colonoscopies and sigmoidoscopies are considered to be effective screening methods for colorectal cancer.
