What is a breast biopsy?
A breast biopsy is a procedure where a small sample of breast tissue is removed for testing. The tissue may be removed using a small needle or surgery, then the tissue sample will be checked for signs of breast cancer or other abnormal cells.
Doctors may recommend breast biopsies following an abnormal result on a mammogram, ultrasound or other breast exams. This can include a lump felt in the breast, nipple problems like bloody discharge or problems internally, like a fluid-filled mass or calcium deposits.
