The USPSTF recommends that women who are 50 to 74 years old and are at average risk for breast cancer get a mammogram every two years. Women who are 40 to 49 years old should talk to their doctor or other health care professional about when to start and how often to get a mammogram. Women should weigh the benefits and risks of screening tests when deciding whether to begin getting mammograms at age 40.
Women over the age of 40 should undergo annual screening mammography. There is no data showing at what age annual screening should stop. If a womanâs life expectancy is greater than five years, she still benefits from screening. The life expectancy of an 80-year-old woman is eight years, so she should still be screened.
