Right here’s the factor, although: Having dense breasts is regular, and fairly widespread—about half of ladies ages 40 and older have dense breast tissue, in keeping with the National Cancer Institute, though your density can change over time. You’re additionally extra more likely to have dense breasts should you’re pregnant or breastfeeding, taking hormone substitute remedy, or in case you have a decrease physique weight, per the Centers for Disease Control and Prevention.
Whereas studying that you’re at an elevated risk of breast cancer could set off panic and confusion at first, Wendie Berg, MD, PhD, says the data needs to be “considered as empowering.”

“It offers a girl with info to debate together with her supplier and to think about having extra screening past the mammogram alone, relying on her different threat elements and tolerance for extra testing,” Dr. Berg, a distinguished professor of radiology on the College of Pittsburgh Faculty of Medication, tells Properly+Good.
Why understanding your breast density is vital
There are 4 classes with regards to breast tissue density: fatty, scattered, heterogeneously dense, and intensely dense. The latter two are each thought of “dense,” however the larger the density class, the upper the breast most cancers threat, Dr. Berg says, including that as much as half of cancers might be missed on a mammogram of dense breasts.
That’s as a result of on a mammogram, dense tissue seems as both white or grey. Sadly, so does most cancers. This creates a “masking impact,” the place malignancies can primarily disguise and go undetected till they’ve grown bigger and the most cancers has progressed to later phases.
This was the case for JoAnn Pushkin.
When Pushkin was identified with breast most cancers at age 46, she was shocked, confused, and angered. She had been getting her beneficial annual mammograms since age 40, however her most cancers was missed till it had reached a later stage and required extra aggressive remedy.
When she came upon why her most cancers evaded the watchful eyes of her medical doctors, she was much more upset. Pushkin was instructed, very nonchalantly by an ultrasound tech, that she had dense breast tissue that will make recognizing most cancers on routine mammograms “a tough discover.”
Though her elevated breast density was apparent on her prior mammograms, nobody ever made her conscious of it. Had she been knowledgeable about her dense tissue or its related dangers, she may have consulted with physicians about her choices for extra testing that may have recognized her most cancers a lot sooner.
“I keep in mind pondering, ‘How is it that I don’t learn about this when it appears so routine?’” Pushkin tells Properly+Good. “How do you’ve a dialog about one thing you don’t know that you’ll want to? Not figuring out this successfully denied me of an early prognosis.”
Fortunately, Pushkin is now a breast most cancers survivor. Since turning into cancer-free, she has used her expertise to teach ladies about breast density. She is now the chief director of DenseBreast-info.org, an academic hub meant to arm individuals with info and sources on all issues breast density.
She has additionally stood earlier than lawmakers on quite a few events to champion legal guidelines that will require suppliers to inform sufferers about their breast density standing—one thing that was not mandated in each state till now.
Below the FDA’s new guidelines, individuals who get mammograms can be knowledgeable of their breast density class in easy-to-understand language, and that info can then be used to information their selections round additional testing or supplemental imaging.
What to do after discovering out you’ve dense breasts
Dr. Berg recommends each particular person planning to be screened for breast most cancers search a 3D (somewhat than 2D) mammogram, no matter breast density. Also called digital breast tomosynthesis or DBT exams, 3D mammograms present radiologists with rather more detailed imaging. Moderately than the usual 4 to eight views included in 2D exams, radiologists view tons of of slides in DBT exams, with out having to take extra views that will expose you to extra radiation.
In case your mammogram reveals you’ve dense breasts, you might also profit from extra supplemental imaging. This may embody breast MRI, ultrasound, and generally contrast-enhanced breast CT scans.
Dr. Berg says MRI is the popular supplemental examination for figuring out difficult-to-detect cancers. Analysis backs this suggestion—quite a few research have decided that supplemental breast MRI is the easiest way to identify most cancers in dense breast tissue.
“It detects extra cancers than every other screening check,” she says. “Amongst 1,000 ladies having a screening mammogram, about 100 can be known as again for extra testing, and 5 or 6 can be discovered to have most cancers. On common, one other one to 3 ladies can be discovered to have most cancers after including screening ultrasound.”
If these ladies had MRIs, a median of 16 extra could be discovered to have most cancers the primary yr, Dr. Berg says, and 7 extra could be identified with most cancers on subsequent screening MRI exams. In different phrases, MRIs can catch breast most cancers at earlier phases than different screening checks, so it’s price speaking to your physician about this feature, particularly in case you have dense breast tissue.
Hurdles for individuals with dense breasts
Though the brand new mandate is a step in the appropriate route, there may be the matter of affording supplemental screening. At the moment, the Inexpensive Care Act requires insurers to completely cowl screening mammograms. The identical can’t be stated for supplemental imaging.
Some states have legal guidelines in place that mandate protection of supplemental screening when it is strongly recommended, however these exams may nonetheless include out-of-pocket bills relying on the insurer, which could deter individuals from looking for extra imaging. MRIs particularly can generally value hundreds of {dollars}.
In a scenario when an individual needs to pursue extra imaging however is anxious about the price, Dr. Berg recommends wanting into amenities that supply a shortened model of breast MRI exams.
“There are over 200 amenities that supply ‘abbreviated MRI’ with direct-to-patient billing at decrease value, normally $250 to $600,” she says. “Abbreviated MRI makes use of fewer sequences and takes much less time, however performs very nicely.”
She provides that now that breast density is taken into account a threat issue for most cancers, supplemental exams usually tend to be lined. What’s extra, there are at the moment many discussions associated to insurance coverage protection of supplemental imaging circulating on a federal stage.
Pushkin has been working alongside Congresswoman Rosa DeLauro (D-Conn.) to lend her assist to the event of a federal regulation that will require insurance coverage suppliers to supply protection of breast most cancers screening, supplemental or in any other case, at no extra value. The Discover It Early Act was launched to Congress in December of 2022 and reintroduced in Could 2023.
Katie Couric, who was identified with early stage breast most cancers after present process a breast ultrasound attributable to having dense tissue, has additionally lent her assist to the proposal. Couric, who generally refers to herself as “dense breasts Katie” in her social media posts advocating for better consciousness of breast density, was current when the invoice was reintroduced.
Pushkin says that, if handed, the brand new regulation, along with the FDA’s new notification necessities, will stop “pointless tragedies.”
“The extra screening beneficial must be inexpensive and accessible,” she says. “It’s vital that after we get everybody educated and have a plan of motion that the plan of motion can occur.”
