There are two types of mammograms, a procedure that checks for abnormalities like lumps and masses in the breast: screening and diagnostic. In the former, each breast is X-rayed in two different positions: from top to bottom and from side to side. Questionable abnormalities sometimes require additional evaluation -- diagnostic mammography, breast ultrasound, and/or needle biopsy. A diagnostic mammogram focuses on an area of breast tissue that appeared abnormal in a screening mammogram. Mammograms are 85% to 95% accurate and will be falsely negative in up to 15% of patients.
