When Should You Start Getting Mammograms? A Guide by Age and Risk

Breast Screening Is Not One Size Fits All

Many women know that mammograms are important but are less certain about when to begin, how often to return or whether family history changes the timeline. For people at average risk, current guidance from major medical organizations supports beginning screening mammography at age 40. The exact schedule after that may be annual or every two years depending on your health history, preferences and your clinician’s recommendation.

The most useful first step is not memorizing a single age. It is understanding whether you are at average risk or may need a more individualized plan. A conversation with your OB-GYN can help you review your history, clarify your risk and decide when screening should begin.

Mammogram Recommendations for Average-Risk Women

The American College of Obstetricians and Gynecologists recommends that screening mammography begin at age 40 for individuals at average risk. The U.S. Preventive Services Task Force recommends mammography every two years from ages 40 through 74. Because professional recommendations differ on frequency, shared decision-making remains important.

A screening mammogram is intended for someone who does not have a new breast symptom. If you notice a lump, nipple discharge, skin dimpling, a change in breast shape or another concerning change, do not wait for your next routine screening date. Contact your healthcare provider for an evaluation. Diagnostic imaging may be more appropriate than a routine screening exam.

Who May Need Earlier or Additional Screening?

Certain risk factors change when screening begins or which tests you need. For example, doctors consider a strong family history of breast or ovarian cancer, a known BRCA1 or BRCA2 mutation, a previous high-risk breast biopsy, chest radiation at a young age, or a personal history of breast cancer. Furthermore, dense breast tissue affects how clearly abnormalities appear on a mammogram.

Having one relative with breast cancer does not automatically change your screening plan. Your provider evaluates which relatives had cancer, their ages at diagnosis, and whether cancer occurred on one or both sides of the family. If patterns suggest an inherited risk, your provider may recommend genetic counseling or a formal risk assessment.

What Happens After Your First Mammogram?

Your first mammogram establishes an important reference point for future imaging. Radiologists compare current images with earlier exams to track changes over time. If you have previous mammograms from another facility, transfer those images before your appointment.

Your report will also describe your breast density. Dense tissue is common, but it makes mammograms harder to interpret and raises breast cancer risk. Additional imaging is not automatically necessary for every woman with dense breasts. Instead, your overall risk, mammogram findings, and personal preferences guide that decision.

Questions to Review With Your OB-GYN

Before your visit, write down the ages at which close relatives were diagnosed with breast, ovarian, pancreatic or prostate cancer. Include relatives on both sides of the family. Bring information about previous breast biopsies, abnormal imaging, chest radiation and any genetic testing. These details can help your provider determine whether a routine average-risk schedule is appropriate or whether a formal risk assessment is needed.

Also ask how often you should return, whether 3D mammography is available, how breast density may affect your plan and where results will be delivered. Screening guidance can change as you age or as your history changes. Revisit the conversation if a relative receives a new cancer diagnosis, you learn new genetic information or you develop a breast symptom.

A clear plan is easier to follow than a general reminder to schedule someday.
