Rectal Cancer

Overview

Colon cancer develops in the large intestine (colon), the lower part of your digestive system. Rectal cancer develops in the rectum, which makes up the last several inches of your intestinal tract. Together, they're referred to as colorectal cancers.

Rectal cancer begins as small clumps of cells called polyps. Although most polyps are noncancerous (benign), some become cancerous over time. Regular screening to find and remove precancerous polyps can prevent rectal cancer from developing. Changes in your diet and lifestyle — such as healthy eating and increasing your physical activity — can help prevent polyps from forming, greatly reducing your risk of rectal cancer.

Why choose Mayo Clinic for rectal cancer

• Experience and expertise. As one of the nation's leading centers for screening and treatment of colon and rectal cancers, Mayo Clinic performs more than 20,000 colonoscopies and hundreds of virtual colonoscopies each year. Mayo Clinic led the way in studying and using virtual colonoscopy and was one of the first to offer it for routine care.
• Multispecialty team. At Mayo Clinic, specialists in medical oncology, gastroenterology, radiation oncology, colon and rectal surgery, radiology, medical genetics, nutrition, and other areas work together to ensure that you receive comprehensive care. Experienced and caring staff also provide support services for you and your family before, during and after treatment.
• Advanced screening techniques. Advances in screening techniques, some of which were pioneered at Mayo Clinic, make early diagnosis possible.
• Minimally invasive techniques. At Mayo Clinic, almost all colorectal surgeries are performed using minimally invasive (laparoscopic) surgery. An advanced procedure called robotic surgery gives surgeons a degree of precision and control that can't be achieved with standard laparoscopic techniques. This typically results in a shorter hospital stay, a faster, less painful recovery, and preservation of normal bowel, bladder and sexual function. Mayo colorectal surgeons are among the nation's most experienced and successful in these types of techniques.
• Comprehensive cancer center. Mayo Clinic Cancer Center meets strict standards for a National Cancer Institute comprehensive cancer center, recognizing scientific excellence and a multispecialty approach focused on cancer prevention, diagnosis and treatment.
