What is a breast biopsy?
A breast biopsy is a procedure that removes a small sample of breast tissue for testing. The tissue is looked at under a microscope to check for breast cancer. There are different ways to do a breast biopsy procedure. One method uses a special needle to remove tissue. Another method removes tissue in a minor, outpatient surgery.
A breast biopsy can determine whether you have breast cancer. But most women who have a breast biopsy do not have cancer.
