My wife wants to know at what age should be her first mamagram?

40 years old. Unless there is a family history, the american cancer society, as well as other reputable cancer societies, recommend annual screening beginning at age 40 years.
50 for sure. The american cancer society reccomends yearly screening beginning at age 40. The us preventative services task force says to start at age 50, if you are low risk, and have a mammogram every other year. If there is any family history of breast disease, begin at 40.
