When Should You Get a Mammogram? Age Guidelines

Mammograms are one of the most effective tools for detecting breast cancer early—often before symptoms appear. But many women still wonder: When should I start, and when should I stop? Here's what the latest research and expert guidelines say about the best age to begin and end routine breast cancer screenings.

What Is a Mammogram and Why Is It Important?

A mammogram is a low-dose X-ray of the breast that helps detect cancer in its early stages—sometimes up to two years before a lump can be felt. There are two main types:

• 2D mammograms: Standard front-and-side breast images
• 3D mammograms (tomosynthesis): Multiple layered images for a clearer view, especially for women with dense breasts

Mammograms are a key component of early detection, improving treatment success rates and saving lives.

When Should You Start Getting Mammograms?

General Guidelines for Average-Risk Women

Leading organizations differ slightly on when to start:

• American Cancer Society (ACS): Start annual mammograms at age 45
• U.S. Preventive Services Task Force (USPSTF): Recently updated to recommend screening starting at age 40
• Mayo Clinic and others: Encourage starting at age 40

‍Bottom line: For most women, starting between ages 40–45 is advised, with yearly or biennial screenings depending on your preference and doctor’s recommendation.

Early Screening for High-Risk Women

You may need to start earlier (as early as your 30s) if you:

• Have a family history of breast cancer
• Carry BRCA1 or BRCA2 gene mutations
• Have had radiation therapy to the chest
• Have dense breast tissue or other high-risk factors

Speak with your doctor about personalized screening plans if you're in a higher-risk group.

Are Mammograms Necessary for Women in Their 30s?

Routine screening is not usually recommended for average-risk women under 40. However, mammograms may be appropriate in younger women if:

• A lump or abnormality is found
• There is a strong family or genetic risk
• Recommended as follow-up to another test

If you're under 40 and concerned about breast changes, talk to your provider about diagnostic imaging options.

When Should You Stop Getting Mammograms?

There’s no one-size-fits-all answer, but most guidelines suggest:

• Continue screenings as long as you’re in good health
• If you have a life expectancy of 10 years or more, mammograms can still be beneficial
• Discuss with your doctor around age 74–80 whether continued screening is right for you

‍Remember: Breast cancer risk doesn't disappear with age, but the decision to stop screening should be personalized based on your health status and goals.

Special Considerations for Breast Health Screening

Men and Breast Cancer

While rare, men can get breast cancer, especially if they carry genetic mutations. Men with a family history should discuss screening options with their physician.

Survivors of Breast Cancer

Breast cancer survivors often require ongoing imaging and follow-up. Screening may be more frequent or include additional imaging like ultrasound or MRI.
