In general, cancer begins in the body when basic, everyday cells turn rogue. When a cell’s DNA is damaged and becomes cancerous, these bad cells continue to divide quickly, even when the body has no use for them. As these unnecessary cells multiply, they begin to form a tumor or tumors. These newly-formed cells often quickly spread to other parts of the body and begin invading and destroying normal tissue.
Specifically, colon cancer (sometimes referred to as colorectal cancer) is a disease that originates in the colon or rectum. Colon cancer and rectal cancer are often grouped together because they have very similar features.
Unfortunately, it is not scientifically clear what causes colon cancer in most instances. However, certain individuals have a higher risk of developing colon cancer.
