Colon cancer is a result of the presence of cancerous tumors in the colon or the rectum. It is the third most commonly occurring form of cancer in the world. It usually starts off with small, precancerous polyps which can turn cancerous over time if they are left unchecked. Hence, screening colonoscopies can help one detect these polyps in the benign stage. Full recovery from colon cancer is possible, especially if the infection hasn’t spread beyond the colon wall.
