What is a mammogram? 

A mammogram is a low-dose x-ray picture of the breast. Mammograms are the best primary screening tool to find breast cancer. Ask your health care provider if and when a mammogram is right for you.

Why should I get a mammogram?

Mammograms can help save lives. They can find breast lumps at an early stage, before lumps are big enough to feel or cause symptoms. Early detection of breast cancer can lead to early treatment options, and better chances of survival.

Mammograms cannot find all problems. Call your doctor or clinic if you notice any change in your breasts, including:

  • a lump
  • thickening
  • liquid leaking from the nipple or changes in how the nipple looks

How is a mammogram done?

  • When you have a mammogram, you stand in front of a special x-ray machine.
  • You will need to take off your shirt and bra.
  • Your breast is placed on a small platform.
  • A clear plastic plate presses down on the breast for a few seconds. You might find the pressure on the breast uncomfortable. 
  • The technologist will take several pictures of the breast.
  • A specialist then looks at the x-ray pictures to see if there are any changes in the breast.

How do I get my results?

  • You and your health care provider should get written results within 30 days after your mammogram.
  • Call if you don’t get your results. Do not assume that everything is normal.
  • Ask for your mammogram. It can be saved on a CD. Keep it to compare with mammograms you get later.

Things to know before you get your mammogram

Follow these tips to help you prepare for your mammogram.

  • Don’t wear deodorant, perfume, lotion or powder under your arms or on your breasts on the day of your exam. Foreign particles could show up in an x-ray.
  • Let the staff know if you have breast implants. They may need to take more pictures than a regular mammogram.
  • Bring prior mammograms or have them sent to the center if possible.
  • Tell the clinic if you have physical disabilities that may make it hard for you to sit up, lift your arms, hold your breath, or dress yourself. Also, let them know if you use a wheelchair or scooter.
  • Talk with the staff about how they will handle issues of modesty that you may have due to your religion.
