If colorectal cancer spreads
Cancer cells can spread from the colon or rectum to other parts of the body and develop into a new tumour. The new tumour is called a metastasis, or secondary tumour. If more than one tumour develops in another part of the body, they are called metastases.
Understanding how a type of cancer usually grows and spreads helps your healthcare team plan your treatment and future care. If colorectal cancer spreads, it can spread to the following:
- nearby lymph nodes (the most common place where colorectal cancer spreads)
- nearby tissues in the abdomen or pelvis
- peritoneum (the membrane that lines the walls of the abdomen and pelvis, and covers and supports most of the organs in the abdomen)
- distant lymph nodes
Taking action against all cancers
The latest Canadian Cancer Statistics report found that of all newly diagnosed cancers in 2017, half are expected to be lung, colorectal, breast and prostate cancers. Learn what you can do to reduce the burden of cancer.
