The risk of cancer increases with age, and colon cancer is included in this factor with 62 being the most common age at diagnosis (McCartney Oberleitner, 2011). Repeated exposure to carcinogens over time can cause mutations in DNA, especially in highly mitotic epithelial cells, resulting in cancerous growths. An immune response in a young and healthy body would destroy the early formation of cancer cells. Unfortunately, individuals of advanced age suffer a decrease in the capabilities of the immune system. This puts them at a higher risk of dysplastic cells multiplying in the colon. Genetics may induce the coding of certain genes within cells to undergo spontaneous mutations. (Labianca, Nordlinger, Beretta, Brouquet, Cervantes, 2010).
