Colon/Rectum Cancer Work-up
Through sigmoidoscopy or colonoscopy, a scope is inserted into the colon to visualize the lining. This may identify tumor size and location. Sigmoidoscopy and colonoscopy are used for screening as well as work-up for cancer of the colon/rectum. Biopsy may be performed at the time of sigmoidoscopy or colonoscopy to any suspicious lesions. Biopsy will identify the histology, behavior, and grade of the tumor.
