Breast most cancers is a scary actuality for a lot of girls and a concern for a lot of extra. Whereas sure danger elements ― reminiscent of having a household historical past of the illness or the BRCA1 gene mutation ― are well-known, others fly dangerously below the radar.
One danger issue that impacts practically half of ladies in the US is having dense breasts, which you will not know you have got till you get your first mammogram.
Till now, well being care suppliers weren’t mandated to share breast density info with their sufferers. As an alternative, steerage diversified from state to state. However as a part of a Meals and Drug Administration-approved replace to the Mammography High quality Requirements Act, healthcare suppliers should now inform sufferers of their breast density and explicitly state the dangers that include dense breast tissue.
There are two fundamental explanation why breast tissue density is necessary, Dr. Kimberly Feigin, interim chief of the Breast Imaging Service at Memorial Sloan Kettering Most cancers Heart in New York, instructed HuffPost by way of e mail.
“The first reason is that women with dense breasts have a higher risk of developing breast cancer than women with non-dense breasts,” she stated.
“The second reason is that screening mammography is less sensitive for detecting breast cancer in dense breasts. This is because breast cancer, which typically looks white on a mammogram, can be ‘masked’ (hidden or obscured) on a mammogram by dense breast tissue, which also looks white on a mammogram,” Feigin added.
Breast density isn’t one thing you’ll be able to change; it’s simply your anatomy. Moreover, you gained’t know you have got dense breasts till a screening is carried out and a medical skilled tells you.
“It is not something that you can feel or know or detect on your own,” stated Dr. Arif Kamal, chief affected person officer for the American Most cancers Society. “In it of itself, it is not an abnormality.”
Mammogram sufferers with dense breast tissue will now get an announcement following their outcomes that reads: “Your breast tissue is dense. In some people with dense tissue, other imaging tests in addition to a mammogram may help find cancers. Talk to your healthcare provider about breast density, risks for breast cancer, and your individual situation.”
And it’s pretty doubtless that you just’ll find yourself seeing this message in your subsequent mammogram paperwork. In line with Kamal, “Forty percent of mammograms demonstrate dense breast tissue, and we know that that increases the risk of breast cancer by one-and-a-half to twofold.”
There are two classes of dense breasts: heterogeneously dense and very dense, based on Dr. Wendie Berg, a professor of radiology on the College of Pittsburgh College of Drugs.
“Heterogeneously dense [tissue], much more common, [is] just patchy areas where there’s glandular tissue, and cancers can be hidden in those areas. Extremely dense [breasts] just absorb the X-rays more, and it makes the mammogram look white, and cancers are also white, and so we just have a hard time seeing them through the denser tissue,” Berg stated.
In some states, your particular density class is required to be in your mammogram outcomes letter, however that’s not a nationwide mandate, based on Berg. However this info is required to be in your medical historical past, so you’ll be able to ask your physician when you’ve got heterogeneously dense or extraordinarily dense breasts. Since most cancers is even more durable to see in these with extraordinarily dense breasts, it’s necessary to know the place you fall.
Breast most cancers is the most typical most cancers in girls in the US subsequent to pores and skin cancers, so all this may be fairly unnerving. However understanding extra about breast density will assist you to higher perceive your most cancers danger and assist you to take further steps to guard your self.
Beneath, docs share what you are able to do in the event you discover out you have got dense breasts:
Chat along with your physician about your lifetime danger of growing breast most cancers.
Dense breast tissue is a danger in itself for growing breast most cancers and for lacking the most cancers altogether on mammograms, based on Berg.
There are lots of different danger elements which can be necessary to weigh, too. Your physician ought to have the opportunity that can assist you calculate your lifetime danger of growing breast most cancers utilizing considered one of a number of danger fashions, Berg stated.
These fashions take into account elements like your breast density, weight, peak, any historical past of most cancers in your loved ones, the age you began or stopped having intervals and your breast biopsy historical past.
Most sufferers get put into considered one of two classes, Kamal stated: An “average risk” particular person has a lower than 20% likelihood of getting breast most cancers within the subsequent 5 to 10 years, whereas a “high-risk” affected person would face a danger of 20% or greater.
A high-risk affected person may gain advantage from “something different from the usual guidelines” for mammograms, Kamal stated, like getting a repeat mammogram each 12 months ― although precisely what individuals at excessive danger needs to be doing varies relying on who you ask.
“The challenge is, in some ways, the guidelines haven’t really caught up yet to what that would be, and so there is a difference of opinion among scientists about what to do next,” Kamal added.
Your breast most cancers screenings could must be extra frequent.
Your physician could suggest extra frequent mammograms — like each six months as an alternative of yearly — and may additionally prescribe extra screenings like breast ultrasounds or 3D mammography.
These extra screenings don’t substitute your annual mammogram.
“It is important still to get your mammogram, it does find a few things that we don’t find on an MRI. … We do get a look at a lot of things, and we do find a good number of cancers,” Berg stated. “It’s just that there’s more to it than that, and it’s important to be aware of that and to not be lulled into a false sense that everything’s fine.”

MRIs are an choice, too.
MRIs discover roughly 3 times extra cancers than mammograms, based on Berg, which make them a strong software for many individuals with a excessive danger of breast most cancers. That features individuals with sure gene mutations, a historical past of radiation therapy to the chest or of us with a breast most cancers lifetime danger that’s greater than 20%.
“MRI is a lot better if the woman has dense breasts or meets other risk criteria,” Berg stated.
You possibly can discuss to your physician about this doable screening software, as you’ll want a referral ― however know that MRIs will not be all the time lined by insurance coverage, stated Berg. In case your breast MRI isn’t lined, there are nonetheless choices.
“There also are centers that offer so-called abbreviated MRI, [and] some of those are direct-to-patient and self-pay situations,” Berg stated. Prices vary from roughly $250 to $650. Berg beneficial utilizing Time To Be Seen, an abbreviated MRI database, to discover a heart close to you.
In line with Susan G. Komen, breast MRIs lead to false positives extra typically than mammograms, which can imply they spur pointless biopsies or follow-up checks. For some individuals, this could possibly be a purpose to not get a breast MRI, however for others, it’s only a vital step to make sure they’re cancer-free — and it’s as much as you to make that decision.
It’s possible you’ll need to take into account genetic testing.
Most cancers-causing mutations may be discovered by way of genetic testing. A few of these mutations can imply your breast most cancers screenings both ought to begin sooner than the beneficial age of 40, or imply that you just’d be eligible for added screenings like MRIs, based on Berg.
Even with out the genetic mutations, different elements could possibly be purpose sufficient to start out testing earlier. “One informal rule that’s out there is to start screening 10 years before the age of diagnosis of a first-degree relative,” Berg stated. “So, let’s say [your] mom was diagnosed at 45 — you should start screening at 35.”
