Mammogram Guidelines: What to Know

Women’s Health • Medically reviewed May 2023by the Cedarcrest Health clinical content committee

Mammograms remain one of the most effective tools for finding breast cancer early, often before it can be felt or causes symptoms. Understanding when and how often to be screened can help you plan this important part of preventive care.

When Screening Typically Begins

Guidelines vary somewhat among medical organizations, but most recommend that women of average risk begin discussing regular mammograms with their provider in their 40s, continuing on a schedule based on personal risk factors and preference. Women with a family history of breast cancer or other risk factors may be advised to start earlier or be screened more often.

A mammogram is a low-dose x-ray of breast tissue that can detect changes long before they might be noticed by touch. The procedure takes only a few minutes, though some women find the brief compression uncomfortable.

Preparing for Your Appointment

• Schedule your mammogram for a time when your breasts are less tender, if you have a menstrual cycle.
• Avoid deodorant, lotion, or powder on the day of the exam, since these can interfere with the images.
• Bring information about any prior mammograms done at another facility.
• Tell the technologist about any breast changes you have noticed.

Being called back for additional images after a mammogram is common and does not necessarily mean cancer has been found. Most callbacks are resolved with extra pictures or an ultrasound.

Talk with your Cedarcrest Health primary care provider about the mammogram schedule that is right for you, based on your age and personal risk factors. Call our Find-a-Physician line at (814) 555-2650 to schedule your screening.
