Rectal cancer is a common diagnosis which is often treated by surgical resection of the cancer. However, cancer treatment can result in changes in bowel function. Faecal incontinence can occur because of cancer treatment, as well as increased defecation. Although these symptoms will improve with time over a few months, making changes, such as dietary ones with nursing support, can help. Having a greater understanding of issues that can occur and ways in which to resolve them can improve both healthcare professional confidence and circumstances for patients with bowel dysfunction.
