The key points below about the benefits and possible risks of screening mammograms can still help you and your doctor decide what is right for you.

There are two types of mammograms.
This decision aid is about screening mammograms.
Mammograms can find some breast cancers early, when the cancer may be more easily treated. Often a mammogram can find cancers that are too small for you or your doctor to feel.
Studies show that a small number of women who have mammograms may be less likely to die from breast cancer.
Each time you have a mammogram, there is a risk that the test:
Experts agree that mammograms are the best screening test for women at average risk. But they don't all agree on the age at which a woman should start or whether it is better for her to be screened every year or every two years.
Here are some of the recommendations from experts:
When to stop having mammograms is another decision. You and your doctor can decide on the right age to stop screening based on your personal preferences and overall health.

No one in my family has ever had breast cancer. So I'm not at high risk for getting it. I talked with my doctor about this, and I read all of the information I could. My doctor says it's my decision, but she is here to answer any questions and talk it over. I'm worried about false positives. I have a friend who has had two biopsies, and many sleepless nights, and it turned out to be nothing. I'm having a tough time deciding. I think for me the best decision is no decision. I'll keep reading and thinking about it. I'm okay with this.
Keiko, 41
I've already talked to my doctor about getting a mammogram when I turn 40 next year. Taking action is really important to me when it comes to my health. My older sister started having mammograms when she turned 40. She got a call once because they found something on her mammogram, but after more testing it turned out to be nothing serious. I want to have that reassurance—the peace of mind is worth it to me.
Jaime, 39
I'm not really worried about getting breast cancer, so I've decided to wait until I'm 50 to start having mammograms. I just turned 40, and I've always been healthy and active. Plus, I don't have any extra risk factors. In the meantime, I'm going to mention any changes I notice in my breasts to my doctor.
Helen, 40
My friend was diagnosed with late-stage breast cancer after finding a lump in her breast when she was 48. She didn't have any risk factors for the disease, so she hadn't had any mammograms before then. I can't help but think that maybe if she'd had a mammogram a year or two before, the cancer may have been found earlier. I'm not at high risk for breast cancer either, but I'm going to keep having my yearly mammogram just to be sure nothing is wrong.
Sally, 46
I travel a lot for my job, and my days are often crammed with back-to-back meetings, so trying to schedule a mammogram is a challenge. But I've managed to do it, and all my mammograms have been normal. Some doctors say that it's okay for women to start having mammograms at 50. I think that's reasonable, and I don't feel like I would be putting myself at much greater risk for missing a cancer by waiting until I'm 50 to get my next one.
