The wall of the colon is made up of layers of tissue. Colon cancer occurs when abnormal cells form in the inner layer of this tissue. The cancer can grow through some or all of the other layers. The stage (extent) of the cancer depends to a great degree on how deep the cancer goes into these layers.
Because the majority of colon cancers begin as precancerous polyps, colon cancer is a potentially preventable disease. Screening and early detection can catch colon cancer at an early stage or before polyps turn into cancer. Colonoscopy is a screen test for colon cancer and is considered the most reliable means for early detection.
Cancer of the colon is rare in developing countries, but more common in Western societies. In the U.S. alone, colorectal cancer is the fourth most common cancer in men and women.1

All surgery presents risk, including da Vinci® Surgery and other minimally invasive procedures. Serious complications may occur in any surgery, up to and including death. Examples of serious or life-threatening complications which may require hospitalization include injury to tissues or organs, bleeding, infection or internal scarring that can cause long-lasting dysfunction or pain. Temporary pain or nerve injury has been linked to the inverted position often used during abdominal and pelvic surgery. Risks of surgery also include potential for equipment failure and human error. Risks specific to minimally invasive surgery may include: A long operation and time under anesthesia, conversion to another technique or the need for additional or larger incisions. If your surgeon needs to convert the procedure, it could mean a long operative time with additional time under anesthesia and increased complications. Temporary pain or discomfort may result from pneumoperitoneum, the presence of air or gas in the abdominal cavity used by surgeons in minimally invasive surgery. Research suggests that there could be an increased risk of incision-site hernia with single-incision surgery. Results, including cosmetic results, may vary. Patients who bleed easily, who have abnormal blood clotting, are pregnant or morbidly obese are typically not candidates for minimally invasive surgery, including da Vinci® Surgery. For more complete information on surgical risks, safety, and indications for use, please refer to http://www.davincisurgery.com/safety/. Patients should talk to their doctors about their surgical experience and to decide if da Vinci Surgery is right for them. Other options may be available. Intuitive Surgical reviews clinical literature from the highest level of evidence available to provide benefit and risk information about use of the da Vinci Surgical System in specific representative procedures. We encourage patients and physicians to review all available information on surgical options and treatment in order to make an informed decision. Clinical studies are available through the National Library of Medicine at www.ncbi.nlm.nih.gov/pubmed.
