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).
After surgery, it was recommended that all the women have two screening mammograms per year. Five years after surgery, most mammograms were being done twice per year, but about 10% were being done only once per year. The mammograms found 158 breast abnormalities and 114 of these (72%) were breast cancer.
