In a specific country? It's interesting to note that the incidence of colon cancer is highest in the westernized countries of North America, Northern Europe, Australia, and New Zealand. And it's even more interesting to note that when a developing country adopts a Western diet, colon cancer rates rise. Would this be something that you could present to an audience?
As other pointed out, "colon" cancer is a cancer specific of the large intestine, whereas "intestinal" cancer could affect any part of the intestine (including the small intestine, i.e. duodenum, ileum and jejunum). If colon cancer runs in your family, you are likely to have FAP, or Familial adenoidal polymyositis, an inherited contractual cancer syndrome. People with the classic type of familiarly adenoidal polyphosphate may begin to develop multiply noncancerous (benign) polyps (growths) in the colon as early as their teenage years. This cancer usually develops in the lower part of the digestive system, including the large intestine (colon) and rectum. However, the FAP syndrome could present a risk factor for the cancer of the small intestine, therefore this person could also carry the genetic mutation that confers cancer predisposition.
