The American Cancer Society recommends the following guidelines for people at average risk for cancer who have no specific symptoms:

  • Yearly mammograms at age 40, continuing as long as you are in good health.
  • Clinical breast exam every 3 years for women in their 20s and 30s and every year from age 40 onward.
  • It is important to be familiar with the way your breasts normally feel so that you can detect any changes that may occur. Monthly breast self-exams can help you with this. Be sure to report any changes to your doctor.
  • Speak with your doctor about the risks, benefits and limitations of adding yearly MRI screening to your yearly mammogram.
