Early detection of breast cancer with screening mammography means that treatment can be started earlier in the course of the disease, possibly before it has spread. Results from randomized clinical trials and other studies show that screening mammography can help reduce the number of deaths from breast cancer among women ages 40 to 74, especially for those over age 50. However, studies to date have not shown a benefit from regular screening mammography in women under age 40 or from baseline screening mammograms (mammograms used for comparison) taken before age 40.

 

Prognosis and survival rate for breast cancer varies greatly depending on cancer type and staging.Mammography is an examination using low-dose X-rays to examine the human breast and is the state-of-the-art technique for the diagnostic of breast cancer.
