What is an MRI Breast Biopsy?
These biopsies use MRI technology to guide a needle into the breast and accurately remove tissue from any lumps or areas of abnormality, that have been identified during routine breast imaging. The information gained from these biopsies is critical to determining what treatments are best and allow your primary care provider to formulate a personalised care plan.
