Colorectal cancer is second only to lung cancer as the leading cause of cancerous deaths. According to the International Agency for Research on Cancer, the estimated annual number of deaths due to colon cancer is projected to nearly double from the current approximate 610,000 deaths to more than one million deaths by 2040, which highlights the importance of detecting this cancerous type at the early stages in order to arrange suitable treatments. Some of the main risk factors for colorectal cancer include diet, obesity, physical inactivity, smoking, heavy alcohol use and advanced age.
