Breast MRI: who actually needs it, and who doesn't
Breast MRI: who actually needs it, and who doesn't
I had my yearly breast MRI last week.
It is not glamorous. It is not comfortable. But it is the right test for me, based on my own risk.
And my favorite part? I get to pick the music. This year I went with alternative 90s rock. Last year it was 2000s pop hits. Good music makes the 30 minute test fly by!
I shared this on Instagram and a lot of you shared that you were getting yours too. Solidarity!
For most women, the mammogram is the plan
A mammogram is still the main screening test for breast cancer. For most women, it is the right one.
I know some of you worry about the radiation. I want to put that worry to rest. A mammogram uses a very small amount of radiation. It is far less than many people think. Experts have done the math, and the good from finding cancer early is much bigger than the tiny risk from the dose. One large review put it at roughly 60 to 1 in favor of screening.
So mammograms are safe. If you are at average risk, getting your regular mammogram is one of the best things you can do for yourself. The recommendation for when to start and how frequently to get one is a bit controversial. For the most part it is recommended to start at age 40 and get one every year.
What a breast MRI adds
A breast MRI is a different kind of picture. It does not use radiation. It uses a magnet and a dye to look at the breast tissue.
Here is why it matters. An MRI is more sensitive than a mammogram. It can find some cancers that a mammogram might miss. That is most true in dense breasts, where the tissue can hide things on a regular mammogram.
That sounds like a reason everyone should get one. But more sensitive is not always better. An MRI also picks up more things that turn out to be nothing. So it is a powerful tool for the right person, and the wrong tool for most people.
Who should ask their doctor about a breast MRI
You may be one of the people for whom an MRI adds real value. It is worth asking your doctor if any of these fit you:
You carry a high-risk gene change, like BRCA1, BRCA2, TP53, PALB2, PTEN, or CDH1.
A parent, sibling, or child carries one of those gene changes, and you have not been tested yourself.
Your lifetime risk of breast cancer is around 20% or higher, based on a risk model that uses your full family history.
You had radiation to your chest between the ages of 10 and 30.
A past breast biopsy showed certain changes, like ADH, LCIS, or ALH (these are cell changes that raise future risk).
You have very dense breasts, or dense breasts plus other risk factors.
You had breast cancer before age 50.
You had breast cancer and you also have dense breasts.
A risk calculator puts your short-term risk above a set line.
If none of these sound like you, a breast MRI is most likely not something you need. If one or more do, that is a conversation worth having.
Why this is a conversation, not a rule
Even if you have these risks, an MRI is not always automatic. This is where you and your doctor talk it through.
An MRI is more sensitive, which can be a real benefit. It can also lead to false alarms, extra scans, and biopsies for things that are not cancer. There is the dye to think about and the worry that comes with waiting on results. And in some cases, insurance may not cover a breast MRI, so it is worth asking what it would cost you up front.
The guidelines do not all agree either. The U.S. Preventive Services Task Force (a national group that reviews screening tests) says there is not enough proof yet to judge the benefits and harms of screening breast MRI. Other expert groups, the ones that set the high-risk categories above, do recommend it for women at higher risk. So what is right for you depends on your age, your breast density, your family history, and your own health story. A good doctor can help you figure out your risk, see which group you fall into, and weigh the pros and cons in plain words.
That is the whole point. Not more tests for everyone. The right test for you.
If you want help figuring out your own risk
Working out your own breast cancer risk, and what screening makes sense for you, is exactly the kind of thing worth having a doctor with time for. Not a rushed answer between other things. A real look at your history.
