A screening mammogram is routinely administered to detect breast cancer in women who have no apparent symptoms. Diagnostic mammograms are used after suspicious results are seen on a screening mammogram or if the patient is experiencing some sign of breast cancer. Some signs include lumps, pain, nipple discharge, thickening of the skin on the breast or changes in the size or shape of the breast.
Both screening mammograms and diagnostic mammograms are also typically covered by health insurance. However, it will likely be subject to deductible and co-insurance standards that your plan requires.
