FAQ

Warning Signs

Colorectal cancer can be asymptomatic in some people. Symptoms may include changes in bowel habits, blood in stools, abdominal pain, or weight loss. However, some people may not have any symptoms, which is why regular screening starting at age 45 is important.

FAQ

Smoking has been tied to an increased risk of several cancers, including colorectal cancer, but there is no direct link established yet.

FAQ

Diagnosis
