List Notes: Male colorectum cancer rate is 100,000 men per year and is age-standardized. An age-standardized rate is the rate that a population would have if it had a standard age structure. Standardization is necessary when comparing several populations that differ with respect to age because age has a powerful influence on the risk of cancer.
Percentage of deaths is the percentage of men in the particular country listed who are diagnosed with colorectal cancer and then go on to die from the disease (many factors can influence this percentage in any particular country such as the state of the health care system, treatment options etc).

1. According to the GLOBOCAN 2008 database, colorectal cancer is the third most common cancer in men (663,000 cases, 10.0% of the total) and the second in women (571,000 cases, 9.4% of the total) worldwide (Incidence rates are substantially higher in men than in women). (a).
2. Almost 60% of the cases occur in developed regions. Incidence rates vary 10-fold in both sexes worldwide, the highest rates being estimated in Australia/New Zealand and Western Europe, the lowest in Africa (except Southern Africa) and South-Central Asia, and are intermediate in Latin America. (a).
3. About 608,000 deaths from colon cancer are estimated worldwide, accounting for 8% of all cancer deaths, making it the fourth most common cause of death from cancer. Colorectal cancer is also one of the most commonly diagnosed cancers in the United States. In 2007, 142,672 people in the United States were diagnosed with colon cancer (72,755 men and 69,917 women), making colorectal cancer the third most common cancer in men and in women. (a.), (c.)
4. The incidence rate (age standardized)of colon cancer in men in the United States is: 34.1 per 100,000 (mortality 9.9), in Canada: 45.4 per 100,000 (mortality 14.4), in The UK: 37.3 (mortality 13.9), Australia: 46.0 (mortality 15.9), in China: 16.3 (mortality 8), and in India: 4.3 (mortality 3.2). (a.)
5. Early colorectal cancer often has no symptoms, which is why screening is so important. Most colorectal cancers begin as a polyp, a small growth in the wall of the colon. As a polyp grows, it can bleed or obstruct the intestine.
   
   The following are colon cancer symptoms in men (please see your doctor if you have any of these warning signs):
   
   Bleeding from the rectum
   Blood in the stool or in the toilet after having a bowel movement
   Dark- or black-colored stools
   Cramping pain in the lower stomach
   A feeling of discomfort or an urge to have a bowel movement when there is no need to have one
   New onset of constipation or diarrhea that lasts for more than a few days
   Unintentional weight loss
