Digital breast tomosynthesis, also known as 3D mammography, is the latest innovation in medical imaging technology that is highly effective in detecting breast cancer at an early stage. 3D mammography can help identify breast cancer as early as two years before a lump can be felt by a patient or a physician, making it an essential study for early detection. At South Jersey Radiology Associates, 3D mammograms are offered as the standard of care for all patients. Today, most insurance plans cover the cost of annual 3D screening mammograms at 100% for women over the age of 40.
