When should screening Mammography commence?

Routine screening mammography, for the general female public, should commence at 40 years of age (except where there is a significant family history) and be performed annually thereafter. However, where there is a family history of a first-degree maternal relative having been previously diagnosed with breast cancer, the screening should commence 5 years prior to the age of diagnosis of the relative but not commence earlier than 25 yrs. of age and older than 40 yrs. of age.
