Breast Cancer Screening Tests and Diagnostic Tools

Screening tests are used to find breast cancer before it causes any warning signs or symptoms. Regular screening tests (along with follow-up tests and treatment if diagnosed) reduce your chance of dying from breast cancer.

Sometimes a screening test finds something abnormal and follow-up is needed. It’s important to get follow-up without delay.

Breast cancer diagnosis

How is breast cancer diagnosed?

A biopsy is needed to diagnose breast cancer. A biopsy removes cells or tissue from a suspicious area of the breast. The cells or tissue are studied under a microscope to see if cancer is present.

It’s important to get a biopsy without delay. That way, if you have breast cancer, it can be treated as soon as possible.
