A new discovery that could improved treatments for breast cancer in women researchers finding a pro team that triggers milk production.

It may also be responsible for making breast cancers.

Aggressive doctor Marc -- Fox News medical eighteen.

NYU land don't medical center joins us now with more.

So here.

I'd tell what is this link.

Well first of -- let's start with the fact that over 200000 women get breast cancer every year it's the number one cancer in women 40000 -- from it.

Two thirds of them Heather are linked to estrogen -- called estrogen receptor positive meaning.

That if you block estrogen in these women they tend to respond in addition to try to get the cancer out we often treat them with hormone therapies to block the estrogen.

But 13 are not positive for this and so we're looking around for other sub types and other treatments called targeted therapies where we can try to help.

The 13 of women that don't have the estrogen receptor positive.

So how would this discovery allow you to do that so this is about a protein called ELF five.

That's actually found when you make milk it's approaching associated with -- -- production.

With feeding infants and also during pregnancy but they've discovered now in a very deciding this discovery.

From Australia and Britain this.

Brand new research is showing that this -- team.

Is also found in very high amounts in women that don't have that estrogen -- positive in fact this protein may be the reason.

That that these breast cancers are resistant so you can imagine what's next if there's a protein there.

And it's.

Causing problems with normal hormone treatment what do we do we target the pro team.

What's gonna come down the pike now is this this ELF five is going to be targeted by an -- the body by an anti virus up -- -- something to block it.

And those 13 of women that weren't responding to hormone treatments are probably gonna respond to this -- very exciting and that helps predict response to therapy.

Right it's called sub typing what you know is it here's where we are with cancer now it's not all the same.

You know one group response to hormones -- other group responds to that chemotherapy another group.

You take out the cancer in this particular group that has this protein it's very aggressive this protein cannot.

Produced milk by the way in breast cancer won't cause breast cancer to produce milk.

But it -- make breast cancer very ugly very aggressive and then the -- deal with that is to get rid of this -- -- block -- So here's the thing breast cancer number one cancer in women affects over 200000 women per year killing 40000.

Is this something they can give women hope and will this help curb those numbers -- Think this will save lives I think this is dramatic I mean look the the key with cancer is always early detection that's -- were all about here.

Mammograms.

-- get checked get screened early detection if you have it what are we gonna do we try to remove -- we try to give you pure.

If we can't or even if we can sometimes we use other treatments hormone treatments if the hormone treatments are working.

Here's a protein that if we block it is going to save lives.

Breast cancer comes in many different varieties in this variety which is a 13 of them.

This will help enormously this is very exciting find -- -- thank you so much doctor Marc Siegel we appreciate you bring it straight to sit.

That is excited -- it.
