The American Cancer Society recommends that women with an average risk of breast cancer should start having yearly mammograms by age 45. Women between 40 and 44 have the option to start screening early. For women aged 55 and older, mammograms can be done every two years or continued yearly, depending on individual health factors and preferences. Women with a higher risk, such as those with a family history of breast cancer or genetic predispositions, may need to start screening earlier and have more frequent exams.
