Abiopsy uses three different angles of mammography to precisely locate the mass in the breast.

stereotactic

Explanation;

Incase a suspicious mass is detected in the breast a stereotactic biopsy which is a non-surgical method  is carried out to precisely locate the mass in the breast for it only allows the breasts to be exposed to the x-rays.The x-rays are converted into electrical signals by electronic detectors and thus the electric signals produce images of the breast that can be immediately seen on a computer screen.Mammogram images are obtained to  confirm that the needle is within the lesion prior to sampling.By doing this the radiologist is able to insert  a needle through a small cut in the skin  after a local anesthetic that numbs the breast  enabling the removal of  tissue samples for examination under a microscope incase calcium deposits are sampled for diagnosis.After the process is done pressure is applied at the opening of the breast to stop bleeding and then it is covered with a dressing.A marker may be placed at the biopsy site inorder to locate it in future if necessary.
