http://www.foxnews.com/health/2013/07/31/hpv-tied-to-three-fold-greater-risk-for-esophageal-cancer/?test=latestnews A new review of previous research links infection with human papillomavirus (HPV) to a three-fold greater chance of esophageal cancer. "This doesn't mean it is present in all (esophageal cancers), but it may be a factor in a certain proportion of cases," said Dr. Surabhi Liyanage, the study's lead author. HPV is a very common sexually transmitted virus that is known to cause cervical cancer, anal cancer and some cancers of the reproductive organs and the upper throat. Liyanage, a graduate student at the University of New South Wales in Sydney, Australia, said there's been a lot of debate among researchers about the role of HPV in cancer of the esophagus because most of the studies to date have been small and used disparate methods that make them hard to compare. According to the National Cancer Institute, nearly 18,000 people - roughly four out of every 100,000 - are diagnosed with esophageal cancer each year in the U.S. and 15,000 Americans die from it annually. Worldwide, esophageal cancer is the eighth most common cancer and responsible for some 400,000 deaths a year, according to World Health Organization data. To get a better handle on the relationship between HPV and esophageal cancer, Liyanage and her colleagues gathered results from all of the studies that have compared patients with the cancer to people without it. The studies focused on esophageal squamous cell carcinoma, one type of esophageal cancer that affects the lining of the esophagus. In each study, esophageal tissue samples from cancer patients and from patients without the cancer were examined to see if HPV was present. The 21 studies Liyanage's group analyzed included 1,223 people with esophageal cancer and 1,415 people without cancer. HPV was found in the esophageal tissue of 35 percent of the cancer patients, compared to 27 percent of the people without esophageal cancer. Taken together, the studies link HPV infection of esophageal tissue to a three-fold greater risk of esophageal cancer, the researchers report in the online journal PLOS ONE. If the general population's rate of esophageal cancer is 4.4 out of every 100,000 people, a three-fold risk increase would raise those chances to 13.2 out of every 100,000. Two vaccines, Cervarix and Gardasil, have been developed to prevent infection with HPV. Some of Liyanage's co-authors serve on advisory boards for the companies that make these vaccines and have received research funding from them. If HPV indeed causes esophageal cancer - and that remains to be determined - it's possible that the vaccines could help prevent the cancer, Liyanage said. "However, this needs to be studied further. The benefits of cancer-preventing vaccines are not seen immediately, but after many years following vaccination," Liyanage wrote in an email. U.S. health officials would like for 80 percent of teenage girls to receive the HPV vaccine, but last week they reported that rates of vaccination appear to be lingering closer to 53 percent. Liyanage said there are also other ways to reduce the risk of developing esophageal cancer, including avoiding smoking and excessive drinking.

Sorry about the first post.

Is there really a reason NOT to get the vaccine?

 Yes, there are a number of reasons.

Search the side effects of this vaccine.

What about the risk I just showed? I am asking for a debate here

I always got my kids all the regular vaccinations. 

I didn't do Gardasil.

It is new enough that it made me nervous to get it for my daughters.  I know there are reports of side effects.  

I will say, my younger daughter (she's 17) wants me to get her the shot, so I am reconsidering.

 You do understand that the HPV vaccines "protect" against only 4 of the 100 or so strains of HPV, right? 

Chances are minimal that it would have any effect at all.

Avoiding risk factors is the better way to go, and without side effects like death, paralysis, neurological problems and all the others that have been reported.

My friends husband is now in remission from esophegeal cancer caused by HPV. He's 65.

Not sure how you avoid HPV totally unless you've never had sex. Who are all the women your spouse had sex with (even once), and who are all the men they've had sex with, and who are all the women that they've had sex with, and so on.

Yes. It's terrible side effects.

Gardasil is NOT a cancer vaccine, and the reality is it only protects against something like 2 of the 15 strains of HPV that cause cancer (the last I read...IDK if that number is different now).
