Breast lumpectomy is the surgical procedure to remove a lump on the breast, usually also involving the removal of the breast tissue around the lump. While not all breast lumps are a sign of breast cancer, breast lumps are usually a cause for concern and should be removed. The removal of the breast lump is usually done via surgery, the part removed depends on the diagnosis by the doctor. You can discuss with your doctor during your consultation to decide on the procedure to be done.
