How Often Should Mammograms Be Done?

The answer to how often mammograms should be done is a layered one. It depends on multiple factors unique to each person, from age and family history to genetics, hormone levels, and lifestyle choices. Decades of medical research have shown that breast cancer likelihood differs across demographics, with certain groups more predisposed than others. Yet, even with clear risk markers, some cases appear without any obvious warning signs.

That’s precisely why routine mammograms remain a useful tool in early breast cancer detection. Catching potential abnormalities early can distinguish a simple treatment from a more complex diagnosis.

In this article, we’ll unpack how frequently mammograms should be done, what affects your screening schedule, and how you can take proactive steps for lifelong breast health—with expert support from Mami Breast Clinic.

Understanding the Importance of Regular Mammograms

A mammogram is a specialised X-ray that examines breast tissue for early signs of cancer, largely before symptoms develop. According to the World Health Organization (WHO), early detection can increase breast cancer survival rates by up to 90% when caught in its earliest stages.

Mammograms can detect tumours as small as two millimetres (far too small to be felt through a physical breast exam), making them vital in saving lives.

How Often Are Routine Mammograms Done?

The number of mammograms depends on your age, medical history, and risk profile. We’ve provided a general guideline based on international and local health recommendations below.

Women Aged 40 and Older

The recommended frequency for women over 40 is every 1 to 2 years. The American Cancer Society advises women between 45 and 54 to get annual mammograms, while those 55 and older may switch to every two years if no high-risk factors are present. In South Africa, the Cancer Association of South Africa (CANSA) supports annual mammograms from age 40 for average-risk women.

High-Risk Women (Any Age)

You may need earlier or more regular screening if you have one or more of the following:

• A family history of breast or ovarian cancer (especially in a mother, sister, or daughter).
• BRCA1 or BRCA2 genetic mutations.
• Previous exposure to radiation therapy in the chest area.
• Dense breast tissue or a history of abnormal mammogram results.

Your healthcare provider may recommend annual mammograms starting between the ages of 30 and 35, sometimes combined with breast MRI scans for these cases.

Women Under 40

Routine mammograms aren’t normally recommended for women under 40 unless there’s a known high risk. However, clinical breast exams and self-checks remain fundamental.

How Often Should a Breast Exam Be Done?

In addition to mammograms, clinical breast exams by a healthcare professional are recommended every 1 to 3 years for women in their 20s and 30s and annually for women over 40. Self-exams should be done monthly, ideally a few days after your menstrual cycle ends, to become familiar with how your breasts normally feel and look.

What Influences How Frequently Mammograms Should Be Done?

Several factors determine the answer to “how often should you get a routine mammogram?”
