About colorectal (bowel) cancer

Colorectal cancer, also referred to as bowel cancer, is the fourth most common cancer. It occurs in men and women and is rare below the age of 45. 

There are high rates of survival in patients diagnosed with early colorectal cancer. The amount of treatment needed depends on the exact location of the tumour within the bowel and whether there has been spread beyond the bowel. Effective treatment and chances of cure are greatly improved with earlier diagnosis.

In addition to the treatment of colorectal cancer, Guy’s and St Thomas’ NHS Foundation Trust is the designated regional centre for anal cancer and offer particular expertise in this area.

The Cancer Centre at Guy's provides a comprehensive chemotherapy and radiotherapy service. We have an active clinical trials portfolio and close links with world class academic departments within Kings College London.
