A mammogram is a digital X-ray picture of the breasts. It is used to detect tumors and cysts and to help differentiate between benign (non-cancerous) and malignant (cancerous) tumors. Mammography is performed to screen healthy women for signs of breast cancer. It is also used to evaluate a woman who has symptoms of a breast disease such as a lump, nipple discharge, breast pain, dimpling of the skin on the breast, or retraction of the nipple.

Mammogram is the most accurate test for breast cancer. Approximately 90% to 95% of breast cancers are detected with mammography. Mammography is important because it can detect cancers before you can feel them with your fingers.

Women should discuss with their personal physician how often to receive breast cancer screening.
