First Mammogram: What to Expect

Your first mammogram is an important appointment – feel confident going into it with these tips.

As we journey through life, certain milestones become part of our wellness routine, and for women, this includes mammograms.

If your first mammogram is coming up, you may feel nervous or have concerns. Knowing what to expect can help you feel informed and at ease, making the exam go more smoothly for all.

What to expect at your first mammogram

Taking charge of your health and scheduling your first (and follow-up routine) mammograms are important parts of your overall healthcare.

“It’s normal to be nervous and want to wait to get your first mammogram,” says Christine Policare, MD, a diagnostic radiologist. “But mammography plays an important role in breast health and finding any problems early, which is often when they are easier to treat.”

What is a mammogram?

A mammogram is specialized medical imaging that uses a low-dose X-ray to see inside the breasts. This procedure is crucial for early detection of breast cancer and helps in monitoring breast health.

How long does a mammogram take?

Typically, a mammogram takes about 20 to 30 minutes from start to finish. The actual compression of the breast only lasts a few seconds for each image.

What happens during a mammogram?

You'll be asked to undress from the waist up and wear a gown. You'll stand in front of an X-ray machine, and a technician will place your breasts, one at a time, on a plate. Another plate will firmly press your breast from above. The plates flatten the breast, holding it still while the X-ray is taken.

During a 3D mammogram, the technician will take pictures in two projections — from above and from the side — to see all the breast tissue.

After their first mammogram, most women say, “Hey, that wasn’t as bad as I thought it was going to be!”

What age should you get your first mammogram?

The general recommendation is to start getting mammograms at age 40. But if you have a family history of breast cancer, your doctor may advise starting earlier.

If there’s breast cancer in your immediate family, such as a parent or sibling, you may want to talk to your doctor about scheduling your first mammogram sooner — likely before your 40th birthday.

What happens after your mammogram?

After the mammogram, your doctor receives a report, which they’ll review before sharing the findings with you.

“We review your mammography results over time, comparing them to look for any changes from one mammogram to the next,” says Dr. Policare. “If your breast radiologist does happen to see something out of the ordinary on your mammogram, it doesn’t automatically mean it’s bad. It could be something harmless, like a cyst or overlapping breast tissue.”

First call back after a mammogram?

If there is a need for further assessment, you might be called back to take additional pictures. This is actually quite common. It doesn't necessarily mean there’s a problem; often, it's just to get a clearer view of an area. Most people who are called back for additional breast imaging receive a good report and go right back to their regular screening schedule.

Tips to prepare for your first mammogram:

Plan around your period: For less discomfort, try to schedule your mammogram for the week after your menstrual period, when your breasts are less likely to be tender.
Skip deodorant and lotion: These can appear as white spots on the X-ray, leading to unclear images. Consider booking an early morning appointment and bringing deodorant to apply after.
Wear comfortable clothes: You will need to undress from the waist up, so skip the romper or Spanx – a two-piece outfit is ideal. Wearing loose-fitting clothes will also keep you comfortable during the procedure.
Think about changes before your screening: Tell the technician about any changes in your breasts, any family history of breast cancer, and if you are breastfeeding or might be pregnant.
Prepare the night before: You can eat, shave and behave as you normally would, except for not applying any products near your chest. Select a comfy two-piece outfit, pack your deodorant and lotion in your bag, and get a good night’s sleep!

And the most important tip? “Whatever you do, don’t skip your annual mammogram,” says Dr. Policare. “It just might save your life!”
