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).
Mammograms can sometimes detect things that look like cancer but are not, and just a âfalse positiveâ result. About one in 10 to one in 12 women will have a questioned abnormality on their screening mammogram. So, if you have mammograms yearly for 10 to 12 years, you are likely to get this call at least once. The more mammograms you have over your lifetime, the more likely you are to be called back for a follow-up â and it could be because of a âfalse positiveâ result. If something is noticed on the mammogram, you may need to have additional testing, such as a diagnostic mammogram, a breast ultrasound and/or a biopsy.
