What is a mammogram?

A mammogram is an x-ray of your breasts to screen for breast cancer.

Who should have a mammogram?

You should have a mammogram if you felt a lump or noticed other changes during a breast self-exam. Talk to your caregiver about when you should start having mammograms.

How do I get ready for a mammogram?

  • Do not use deodorant, powder, lotion, or perfume. These products may cause particles to appear on your mammogram.
  • Wear a 2-piece outfit.
  • If you are breastfeeding, express as much milk as possible before the mammogram.
  • Bring a list of the dates and places of your past mammograms and other breast tests or treatments.
  • If your breasts are tender before your monthly period, do not have a mammogram during this time. Schedule your mammogram to be done 1 week after your period ends.

How is a mammogram done?

A top view and a side view x-ray are usually done for each breast. Tell caregivers if you have breast implants or breast problems before you have your mammogram. You may need extra x-rays of each breast.

  • You will be given a hospital gown. Take off your clothes from the waist up. Wear the hospital gown so that it opens in the front.
  • You will sit or stand next to a small x-ray machine. The caregiver will help you place one of your breasts on the x-ray plate. Your arm and breast will be moved until your breast is in the correct position.
  • Your breast will be gently pressed between 2 plastic plates for a few seconds while the x-ray is taken. This may be uncomfortable.
  • You will be asked to hold your breath while the x-ray is taken. Another x-ray will be taken of the same breast after the position of the x-ray machine has been changed.
  • Your other breast will be x-rayed the same way.

What happens after my mammogram?

Your breasts may feel tender for a short while after the mammogram. You may resume your regular activities. Ask your caregiver when you should receive the results of your mammogram.

What are the risks of a mammogram?

You will be exposed to a small amount of radiation. Some breast cancers may not show up on mammograms.

When should I contact my caregiver?

Contact your caregiver if:

  • You cannot make your appointment on time.
  • You do not receive your results when expected.
  • You have questions or concerns about the mammogram.
