Answer

The primary purpose of Mammogram is to detect breast cancers.

How does mammogram differ with age?

Answer

In young women the breast is extremely dense . As women age there is fatty infiltration of the breast associated with atrophy of glandular tissue. Fat is lucent and is dark in mammogram. Glandular tissue and cancer are dense and white in mammogram. Hence it is difficult to distinguish cancer from normal dense glandular tissue in young women.
