There are two main types of mammography. Screening mammography is the type you are probably most familiar with. This type of mammogram is the kind you have annually or on a regular basis as recommended by your doctor. Diagnostic mammography is the other type. Diagnostic mammograms are recommended if you’re experiencing a breast-related symptom, like nipple discharge or a lump, or if something suspicious or unclear was seen on a screening mammogram. You may also need a diagnostic mammogram if your doctor recommends a follow-up mammogram in between your regularly scheduled screening mammograms. Both types of mammograms are performed at Ochsner facilities using 3D mammography to capture the most detailed images of the breast tissue.
