Breast Cancer Screening

What Is Breast Cancer?

Breast cancer is a tumour that starts from cells in the breast and can spread to other areas of the body.

Normally, the cells in your breasts grow and reproduce themselves in a controlled manner. Breast cancer occurs when the cells grow abnormally, or in an ‘out-of-control’ way. In time, the abnormal cells can form lumps or tumours.

Breast cancer can happen at any age. In most cases, it occurs in women over the age of 50.

In Ontario today, women who are at average risk for breast cancer and are 50 - 74 years of age should have a mammogram every two years. Find out where you can go to get screened.
