There's some encouraging news in the fight against cervical cancer a new study in the lancet oncology journal found that an HPV vaccine called a server X. Offers even better protection against HPB than previously thought. Joining us -- to discuss these findings and the impact they may have on screening and the rates of cervical cancer worldwide is doctor -- moderates ABC news contributor and director of the division of gynecology at saint Luke's Roosevelt hospital -- -- Thanks so much for joining us let's go right into this the -- from this is really. That some believe. This study shows that screening. Of a cervical cancer and pap smears and may be able to be reduced because of the effectiveness of this -- team. Right so it looks like if somebody gets the vaccine that eleven or twelve before sexually active that this may actually. Alleviate the need to get pap smears and that's where where -- jumping way ahead. But that's reading into these studies and one of the -- was done in Finland and the person said. We think that if our data is correct. -- maybe one pap smear. In a woman's life will be necessary. Basically this study showed that this specific vaccine protects against other strains of HPV that wasn't even designed to target again so let's get it right they say OK how many strains of HPV are there blood there's over a 120 -- -- about ten. Very bad strains we call them uncle Janet strains of HPV. So that can cause cervical cancer or even -- cervical cancer so the bad ones -- 1618. They're two vaccine to guard itself which is the power -- the older one but the first one and that covers 1618. -- -- -- -- -- -- -- And this new one server X which just covered 1618 and he'd say well why when I wanna take the one that covers for its -- -- one covers two. The importance of these studies and they don't exactly understand but this. Vaccine seems to protect against a lot more strains and it was it's designed to it was designed to really cross cover but they -- -- across covered against. About five of the really bad -- in addition to sixteen AT and thus far they haven't found that Gardner -- other HPV vaccine does cover against that's just it just does a little bit but not as as does -- -- and trying to figure out why and it's remind us how common as cervical cancer is right so in this country it's not that -- -- about 121000 cases that sounds like a lot. The rate has gone down and down down. Pap smear is called pods could -- he's going to the doctor that's pretty much if you do that the chances of getting several cancer really rare. In this country people that -- of cancer people that really hasn't been to the doctors. It's a huge worldwide problem. I mean 500000. Cases I think worldwide each year so it it's a big issue. -- don't see you know at the studies conducted and how reliable the findings are mean is this something that we can take to the bank at this point about this specific vaccine. But it looks like this vaccine what's important about this is. We spoke about -- -- cancer. Either of the vaccines tends to prevent cervical cancer. But there's something before cervical cancer which is really just the pained him to go to the doctor nickel cost -- and -- it. Pre cancerous lesions. And if you speak to any of your friends I promise you they've had an abnormal pap -- Brian eighths Friday night and I have cancer and oh my god -- cancer cells it looks like. This new vaccine tends to prevent that occurrence and even happening. There are some that say this could be an excuse for insurance companies -- not cover. Pap smears and right routine screenings is that something the medical community is talking about well if -- really really works and we don't need pap smears and the data really shows that this can prevent. The major strains. Then I would agree we don't -- -- though he were years away from that certainly this is encouraging -- regards to cervical cancer. And the vaccine in the capabilities of these vaccines can you envision a day where we don't have cervical cancer. And it's eradicate Aaron absolutely this is just the beginning with -- vaccines. Two strains in the nose and cross coverage they're gonna increase the number of strains and the public -- up -- hundred strains it's not that hard to have to work on it. And the other new thing is going to be. For people that even -- cervical cancer or have precancerous lesions -- talking about vaccines. That can cure that they -- turn the body on to fight this. That's exciting I mean what does this indicate if -- -- for other cancer blood that's gonna be that this is the first vaccine for cancer and it really yes. There's a lot of resistance of some parents is a lot of confusion over this safety issues. There's been you know if you go on the blog -- you start seeing mother saying my kid was normal got the vaccine guard -- she's not normal anymore. There -- concerns do we. Just two girls to -- frank -- -- went on to -- running controversy but still some encouraging initial and animation that's doctor Jack Morris thank you so much.
