Proliferative benign breast conditions

There are many different types of benign (non-cancerous) breast conditions.
Most do not have any effect on the risk of developing breast cancer and once diagnosed do not require any treatment or follow-up. However, a few benign breast conditions have been linked to an increased breast cancer risk. If you have a benign breast condition where the breast cells are described as “proliferative” (which means that the cells are growing too much) and “atypical” (which means that the cells do not look normal) then your risk of breast cancer will be increased by up to five times the average.

Benign breast conditions where the cells are proliferative and atypical are uncommon. Most benign breast conditions (for example cysts, fibrocystic disease and fibroadenomas) do not increase the risk of breast cancer. However, if you have had a diagnosis of a benign breast condition and are unsure or worried about your breast cancer risk, you should speak to your doctor.
