how often should you get a mammogram

For women at average risk of breast cancer, the general recommendation is to get a mammogram every 1 to 2 years starting at age 40. The American College of Radiology, Society of Breast Imaging, American Society of Breast Surgeons, and National Comprehensive Cancer Network recommend annual mammograms starting at age 40. The U.S. Preventive Services Task Force (USPSTF) recommends biennial (every 2 years) mammograms from age 40 to 74. The American Cancer Society suggests women aged 45 to 54 get mammograms every year, and women 55 and older can switch to every other year or continue yearly screening based on their preference. Women should continue screening as long as they are in good health and have a life expectancy of at least 10 years. Women at higher than average risk due to factors like family history, genetic mutations, or dense breast tissue may need to start mammograms earlier (around age 30) and might require additional screenings like breast MRIs annually. In the UK, routine mammograms are offered every three years for women aged 50 to 71, though women aged 40-49 may get annual mammograms if at higher risk. Decisions on when to start and the frequency of mammograms should ideally be made in collaboration with a healthcare provider, considering individual risk factors and health status.
