Quick answer: The American Cancer Society recommends a yearly breast MRI plus a mammogram, typically starting at age 30, for women at high risk, such as those with a BRCA1 or BRCA2 gene change or a lifetime risk of about 20% to 25% or more. Breast MRI adds to a mammogram; it doesn't replace it.
Breast MRI is one of the most sensitive tools for finding breast cancer, but it isn't meant for everyone. Whether it makes sense for you depends mostly on your personal risk. Here's who the guidelines say should get one, how the exam works, and what to ask before you book. You can compare MRI centers near you once you have an order.
Who should get a breast MRI for screening?
The American Cancer Society (ACS) recommends a breast MRI and a mammogram every year, typically starting at age 30, for women at high risk. Its high-risk list includes women who:
- Have a lifetime breast cancer risk of about 20% to 25% or greater, based on risk tools that rely mainly on family history
- Have a known BRCA1 or BRCA2 gene change
- Have a first-degree relative (parent, sibling or child) with a BRCA1 or BRCA2 change and haven't been tested themselves
- Had radiation therapy to the chest before age 30
- Have Li-Fraumeni, Cowden or Bannayan-Riley-Ruvalcaba syndrome, or a first-degree relative with one
The ACS says the decision to follow this guideline should be made with your healthcare providers, and that your risk should be reviewed over time.
What about women at average or moderate risk, or with dense breasts?
For women whose lifetime risk is under 15%, the ACS recommends against MRI screening. For women with a lifetime risk of 15% to 20%, and for women with extremely or heterogeneously dense breasts on a mammogram, the ACS says there isn't enough evidence to recommend for or against yearly MRI.
That doesn't close the door. OncoLink, from Penn Medicine, describes an abbreviated or "fast" breast MRI that takes about 10 to 15 minutes and may be used with mammograms for women with dense breasts who don't meet full MRI criteria. OncoLink notes that many plans don't cover it and that out-of-pocket costs typically run about $300 to $400. If your mammogram report mentions dense breasts, ask your doctor whether extra screening fits your situation.
Why else might a doctor order a breast MRI?
Beyond screening, OncoLink lists several other reasons: looking more closely at a mammogram finding that needs follow-up, evaluating a new breast cancer diagnosis, follow-up after breast cancer treatment, and checking whether a breast implant has ruptured.
In every case, MRI works alongside a mammogram rather than replacing it. OncoLink notes the two are often used together, sometimes alternated every six months, depending on your care team.
What is a breast MRI like?
You lie face down on a padded table, with your breasts resting in openings so they aren't compressed the way they are for a mammogram. OncoLink says the exam takes about 45 to 60 minutes and uses no radiation. The scanner is loud, so you'll be offered earplugs or headphones.
Contrast is almost always used. OncoLink explains that a gadolinium contrast agent is given through an IV, except when the scan is only checking for a ruptured implant. Read more in our guide to MRI with or without contrast.
Preparation is usually simple: you can eat and drink normally unless told otherwise, remove jewelry and piercings, and tell the technologist about any metal or devices such as a port, pacemaker or implants. If tight spaces worry you, ask about medication to help you relax; our guide to MRI options for claustrophobia may help too.
Does insurance cover a breast MRI?
It depends on your plan and your risk level. OncoLink notes that breast MRI costs more than a mammogram and that coverage varies, so check with your insurer before you book. If your plan requires approval first, our guide to a denied MRI prior authorization walks through your next steps, and our guide to MRI costs without insurance explains how to compare self-pay prices.
OncoLink also points out that not every imaging center has breast MRI equipment or radiologists who read these exams, so confirm that before you schedule.
Frequently asked questions
At what age should high-risk women start breast MRI?
The American Cancer Society says women at high risk should get a breast MRI and a mammogram every year, typically starting at age 30. Your doctor may suggest a different plan based on your history.
Can a breast MRI replace a mammogram?
No. The American Cancer Society says that when MRI is used, it should be in addition to, not instead of, a screening mammogram. The two tests find different things and work best together.
How long does a breast MRI take?
OncoLink says a full breast MRI takes about 45 to 60 minutes. An abbreviated or fast breast MRI takes about 10 to 15 minutes.
Does a breast MRI use contrast?
Almost always. OncoLink says a gadolinium contrast agent is given through an IV, except when the exam is only checking for a ruptured breast implant.
Should I get a breast MRI if I have dense breasts?
Possibly, but it isn't automatic. The American Cancer Society says there isn't enough evidence to recommend for or against yearly MRI for women with dense breasts alone. Ask your doctor whether supplemental screening, such as an abbreviated MRI, fits your risk.
Find an MRI near you
Not every imaging center offers breast MRI, so call ahead to confirm. Search MRI centers near you by state and city, or start with a state page such as MRI centers in California.
