A biopsy is a procedure where breast tissue is removed and examined by a pathologist to determine whether cancerous cells are present. There are several different types of biopsies. A radiologist or surgeon can use ultrasound, mammography or MRI to guide a biopsy ensuring the correct area is sampled.

Biopsies are performed at both the Branson and General sites of North York General Hospital by a radiologist or surgeon.
