Abnormal findings on a breast MRI often are not cancer. If the
MRI has an abnormal result, your doctor will do other testing to find out if
the problem is serious. This may involve doing an ultrasound test or a
biopsy, or both.
Sometimes your MRI test
results may be different because you were tested at a different medical center
or earlier test results are not available to compare to the new test
An MRI may be more likely to report a problem in the breast when
a problem is not there (false-positive) than other tests. A
false-positive result may lead to more tests when no serious problem is
present. For more information, see the topic
Breast Cancer (BRCA) Gene Test.
is a safe and valuable test for looking at your breast, it is much more costly
than other methods, and it may not be available in your area.
MRI machines are now made so that the magnet does not completely surround you.
Open MRI is useful for people who are claustrophobic or obese. But these
machines are not available everywhere. Also, these machines may not be able to
do all the studies needed to check for problems. Open MRI can be used to guide
treatments (interventional treatments) or procedures, such as a biopsy.
Contrast material that contains gadolinium may cause a
serious problem (called nephrogenic systemic fibrosis) in people with
kidney failure. Tell your doctor if you have serious
kidney disease before having an MRI scan.
