Do you get any symptoms of colon cancer before it's too late?

Some times: Change in bowel habits with a cancer in the left side colon may be an early symptom, others such as anemia, intestinal obstruction, weight loss usually occur late. Screening colonoscopy and fecal ocult blood testing help in early diagnosis.

Yes, sometimes: Symptoms include bleeding, change in bowel habits, unexplained weight loss. However, colon cancer can occur without symptoms. That s why sceening colonoscopy in asymptomatic patients is warranted.
