In brief: Biopsy
A biopsy is needed to be sure and start treatment, but other ways it may be suspected is a positive stool blood test, blood tests, and ct scan.

In brief: Biopsy
Colon cancer is most frequently diagnosed following an endoscopic procedure such as a colonoscopy or flexible sigmoidoscopy.
The cancer is biopsied at that time, leading to the diagnosis.

In brief: Most common
Unfortunately, the most common cause of a mass in the colon or rectum, found on either physical examination, colonoscopy or another study such as ct, is cancer.
The only way to confirm the diagnosis is by obtaining a small sample of tissue (biopsy) and having a pathologist examine it under a microscope.
