Benign tumours
1-minute read
Tumours are abnormal growths in the body. They are caused by cells in the body dividing more than normal or not dying when they should. Tumours can be either benign or malignant (cancerous).
Benign tumours are not cancerous and only grow in one place. They do not spread to or invade other parts of the body, but they can be dangerous if they press on vital organs, such as the brain. Treatment for benign tumours, if it’s needed, usually involves surgery. Once removed, benign tumours don't usually grow back. Some examples of benign tumours include lipoma, uterine fibroids, or acoustic neuromas.
Some specific types of benign tumours can turn into malignant tumours and should be monitored closely by your doctor. These include certain types of polyps that can occur in the colon.
