Colorectal cancer develops in the cell lining of the colon and rectum. Cells may form benign (non-cancerous) growths called polyps. Over a period of years, a series of DNA mutations can occur, leading polyps to become malignant (cancerous).

  • About 26,900 Canadians will have been diagnosed with colorectal cancer in 2020

Screening and detection Footnote 2,Footnote 3
