How Often Should You Get a Mammogram?

“Do I need a mammogram every year?”
“Is once every two years enough?”
“My last mammogram was normal. Do I really need another?”

There is no single answer that applies to every woman. How often you should get a mammogram depends on your age, breast cancer risk, family and personal history, and the screening guideline being followed.

Most importantly, a normal mammogram does not mean you never need another one. Breast screening is most effective when repeated at appropriate intervals.

What Is a Screening Mammogram?

A mammogram is a specialised X-ray examination of the breasts.

A screening mammogram is performed in women who do not have breast symptoms and helps look for signs of breast cancer before noticeable changes develop.

A diagnostic mammogram, on the other hand, may be recommended to investigate a breast concern such as a lump, nipple discharge or an abnormal screening result.

So, when we talk about getting mammograms every one or two years, we are generally referring to routine breast cancer screening.

At What Age Should Mammogram Screening Begin?

Screening recommendations vary slightly between major medical organisations.

The U.S. Preventive Services Task Force recommends mammography every two years from ages 40 to 74 for women at average risk.

The American Cancer Society recommends that women aged 40 to 44 have the option to begin annual screening, women aged 45 to 54 undergo annual mammograms, and women aged 55 and above may switch to screening every two years or continue annually.

This is why your screening plan should consider your individual risk rather than age alone.

Does Family History Change How Often You Need a Mammogram?

It can.

Having a mother, sister or daughter with breast cancer can increase your own risk. The number of relatives affected and their ages at diagnosis can also be important.

Some women at higher risk may need earlier or additional breast screening. Women at sufficiently high risk may be advised to have mammography along with breast MRI.

A breast specialist can assess your personal and family history and help determine an appropriate screening plan.

What If Your Last Mammogram Was Normal?

A normal mammogram is reassuring, but it reflects what was seen at that point in time.

Breast tissue can change, which is why mammography is not intended as a one-time test. Continue screening according to the interval recommended for you.

What If You Notice a Lump Between Mammograms?

Do not wait for your next screening appointment.

A new breast lump, nipple discharge, nipple retraction, skin dimpling, unexplained swelling or another persistent breast change requires clinical assessment, even after a recent normal mammogram.

Screening is for women without symptoms. A new symptom needs evaluation.

Depending on the concern, a breast doctor may recommend a clinical examination, diagnostic mammography, breast ultrasound or further investigation.

What About 3D Mammography?

3D mammography, or Digital Breast Tomosynthesis (DBT), captures images from multiple angles, allowing breast tissue to be examined in greater detail.

At Prajnam Breast Centre, breast screening includes 2D and 3D digital mammography, along with advanced breast ultrasound and further diagnostic evaluation when clinically required.

So, When Is Your Next Mammogram Due?

For many women at average risk, recognised guidelines recommend mammography every one or two years beginning around age 40, although recommendations vary.

Your family history, personal history and overall breast cancer risk can influence what is appropriate for you.

Don’t simply remember when you had your last mammogram. Know when your next one should be.
