Breast Biopsy (2016)
What is a breast biopsy?A lump in the breast can be found during a self-exam, an exam by the doctor or on a mammogram image. A breast biopsy is performed to determine whether a lump is cancer or caused by something else. The doctor will remove a small amount of breast tissue from the lump. The tissue is sent to a lab and tested for signs of cancer. In this kind of breast biopsy the doctor uses ultrasound or some other kind of imaging system to help guide the small needle to the right place, so a small amount of the tissue can be collected. The doctor usually has test results in a few days.
