Your First Mammogram: How to Prepare and What to Expect

First mammogram

Getting your first mammogram can cause some anxiety, but it’s an essential step in taking care of your breast health. Mammograms are an important tool for detecting breast cancer early when it’s most treatable. We’re here to help. We’ll walk you through what to expect during your first mammogram and how to prepare for it, so you can go into the appointment feeling confident and informed.

So, what is a mammogram?


Before we dive into what to expect, let’s start with the basics. A mammogram is a specialized low dose x-ray of breast tissue. A radiologist will examine the mammogram images to look for masses or tumors, calcifications, and abnormalities in the breast tissue that signal the potential of breast cancer. Calcifications are small deposits of calcium that appear as white spots on a mammogram. Most are benign (non-cancerous), however certain patterns of calcifications are suspicious and may require more testing.

After your first mammogram, a radiologist will compare your current mammogram with prior mammograms to look for any changes or developments over time. Comparing previous images to current ones makes it easier to spot abnormalities. That’s why it is important to get regular mammograms.

How to prepare for your first mammogram

Scheduling the appointment


Plan ahead and select a time that works well with your schedule whether it’s over your lunch hour, before work, or later in the day – so there’s no barrier to skip this important health screening.

Choosing the right time

Schedule your mammogram when your breasts are least likely to be tender and swollen, to reduce discomfort and to get good images. The week after your period is usually the best time, as breast tenderness is often more pronounced just before or during menstruation.

What to wear

Wear a comfortable two-piece outfit to your appointment. You’ll need to undress from the waist up, so choose a top that’s easy to remove.

Skip the deodorant

On the day of your mammogram, avoid wearing deodorant, antiperspirant, body lotion, or powders on your arms and chest area. Substances in these products show up on the imaging and may lead to inaccurate readings. Bring along your daily must-have supplies in your purse, to apply when you get dressed after the procedure.

Educate yourself

Understanding the procedure and why it’s important is the first step. Knowledge is empowering, and it can help ease any anxiety you may have.

Support system

Consider bringing a “breastie” – a best friend or family member with you for emotional support. Having someone familiar by your side can make the experience less intimidating.

What to expect during your first mammogram

The mammogram experience

When you arrive, you’ll be greeted by a friendly radiologic technologist who will bring you to the room where the mammogram will take place. She will explain the procedure and answer any questions you have. The technologist will leave the room to allow you to undress from the waist up and change into a short gown that snaps in the front to wear during the procedure. You may be asked to remove any jewelry that might interfere with the imaging.

During the procedure, for your privacy, you and the technologist will be the only people in the room. The technologist will help you position in front of the mammography machine. Accurate positioning is essential to obtain clear images of the breast tissue.

First, the technologist will place one breast on a support plate. Then, a plate will lower and compress the breast and the machine takes an x-ray image. This compression is necessary to spread out the breast tissue evenly, reduce the thickness of the breast, and ensure clear imaging. While the compression may cause some discomfort, the technologist works to make it as brief and tolerable as possible. To avoid blurry pictures, you’ll be asked to remain as still as possible and may be asked to hold your breath for a few seconds. Multiple images from various angles will be taken to provide a comprehensive view of the breast.

The same process is then repeated with your other breast. The whole procedure goes by fast and usually only takes 30 minutes or less. After the technologist finishes taking images, you will be able to get dressed and leave.

Mammogram results

The images are reviewed and interpreted by a radiologist. Don’t worry – most mammogram results are normal. Even if an abnormality is found, it does not necessarily mean you have cancer. You will be contacted if further tests, such as a follow-up diagnostic mammogram, breast ultrasound, or a breast biopsy is required to clarify the results.

You’ve got this!

While your first mammogram is a new experience, it’s a quick and vital screening procedure that could save your life. With the right preparation and knowledge, you’ll breeze through your first mammogram and be on your way to better breast health. Congratulations on taking a proactive step of self-care!
