A computerized tomography scan, or CT scan, is a type of X-ray that uses a computer to make cross-sectional images of your body. The media injected to perform CT angiography is called a contrast material because it lights up blood vessels and tissues that are being studied.
1. Most women who have a mother, sister, or grandmother who had breast cancer at the age of 50 or older, or who are at high risk of breast cancer because of obesity or other reasons, should have regular mammograms (every one or two years) starting at age 40.nfortunately, younger women tend to have denser breasts, which often look white on a mammogram. Since cancer also shows up as white, mammograms are less accurate for younger women (and other women with dense breasts).
Mammography facilities are now required to provide patients with written results of their mammograms in easy-to-understand language within 30 days of the mammogram. Patients may also obtain their original mammogram (not a copy) from the facility so they may compare the results with previous mammograms.
