Breast cancer

Trustworthy information about breast cancer, including diagnosis, treatment, side effects and wellbeing

Overview

Breast cancer is one of the most common cancers in women, and it also affects some men.

It usually starts in the parts of the breast related to milk production (the lobules and ducts). It's most often found when it has spread to surrounding breast tissue. There are 2 main types of breast cancer: invasive ductal carcinoma (the most common) and invasive lobular carcinoma.

Breast cancer has one of the highest 5-year survival rates of all cancers if it's diagnosed early.

A breast cancer diagnosis can be a shock. Find helpful information in Just diagnosed, or call Cancer Connect on 13 11 20 to talk it through with our qualified professionals.
