Common signs include blood in stool, changes in bowel habits, stomach pain, unexplained weight loss, and fatigue. Some people have no early symptoms.
Is there a treatment?

Who is most at risk?
Risk is rising in people under 50. Key factors include family history, genetic conditions, inflammatory bowel disease, or a history of radiation to the belly or pelvis.

Doctors use colonoscopy, stool DNA tests, sigmoidoscopy, and CT scans. A biopsy is typically performed to confirm a definitive diagnosis.
