Colorectal cancer (CRC), cancer of the colon and rectum, is the second leading cause of deaths due to cancer in US. Based on the location, it can be classified as rectal cancer or colon cancer. Most CRC begins as benign adenomas, or polyps that grow on the inner lining of the colon or rectum. These growths spread very slowly, taking from 10 to 20 years to become cancerous. Regular screening tests can identify and remove polyps before they become cancerous. Most cases of colorectal cancer occur in people over 50. Although colorectal cancer is responsible for thousands of deaths every year, it is highly treatable if caught early.

Nearly 70% of patients are > 65 years old and mostly males are affected. For males incidence rate is 57.1 and death rate is 21.2 per 100,000. For women incidence rate is 42.4 and death rate is 14.9 per 100,000. In california about 160,000 new CRC cases added to the database each year. CRC is the 3rd most commonly diagnosed cancer among California men and women (14,114 cases and 5,189 deaths in 2012), and accounts for 9% of all newly diagnosed cancers. CRC is 2nd most common cause of cancer death among Californians (men and women combined).

Clearly colorectal cancer is an important public health problem.
More than half of all colorectal cancers occur without any known cause. Risk factors for colorectal cancer include age (being over 50), previous colorectal cancer, having a history of adenomatous polyps, family h...

...eing of the population in mind, this observation gives further impetus to investigating prevention and treatment strategies among this subgroup of the population. Screening research, recommendations and implementation is an obvious priority. While there are many questions to be resolved, it is apparent that many facets of colorectal cancer are becoming increasingly understood and prospects for prevention are becoming apparent. Making colorectal cancer a form of cancer for which a large proportion of deaths may be preventable is a success for epidemiology. Achieving colorectal cancer control is the immediate challenge.
