Research Reveals Oral Sex May Be Leading Cause of Mouth, Throat Cancers

    Not sure if this has been posted here yet.

    Original article: http://news.yahoo.com/research-reveals-oral-sex-may-leading-cause-mouth-195800608.html

    Mouth and throat cancer, called oropharynx cancer, used to be a disease seen most commonly in elderly persons.

    Tobacco smoking and alcohol use were known to be the leading causes of oropharyngeal cancer. Today, oral sex is listed as the leading cause of cancer of the mouth and throat.

    New research, published in the Journal of Clinical Oncology, demonstrates that human papillomavirus, HPV, is the leading cause of cancer of the oropharnyx in the U.S. The number of people diagnosed with HPV-related oral cancers in the U.S. tripled from 1998 to 2004.

    Currently, as NPR reports, almost 10,000 new cases of oral and throat cancer are diagnosed each year, with a 28 percent increase in incidence since 1988. Interestingly, the majority of those who are being diagnosed with the HPV-related oropharyngeal cancers are men. This leads researchers to wonder if the vaccine against HPV that is recommended for teenage girls may be affording that gender with protection against oropharyngeal cancer, as well as the currently known protection against cervical cancer.

    Researchers have noted a marked drop in non-HPV-related mouth and throat cancers since the American population has begun to turn away from tobacco smoking.

    The oropharyngeal cancer most commonly affects the tonsils, palate, base of the tongue and the upper throat. Whereas this type of cancer was previously seen most often in aged patients, it is now more common at younger ages, including baby boomers and their juniors, reports Bloomberg News.

    HPV is the most commonly transmitted sexual disease, but as Dr. Gregory Masters, an oncologist at the Helen Graham Cancer Center in Delaware reminds us, research is not yet clear that oral sex is the main or only transmission factor in this cancer,

    Dr. Maura Gillison, author of the research published in the Journal of Clinical Oncology states that persons who have had six or more partners on whom they've practiced unprotected oral sex are eight times more likely than those who have not had oral sex to develop the HPV-related mouth and throat cancers, reports CBS News.

    Merck, the pharmaceutical company that manufactures the HPV vaccine, has issued a statement that there are no current plans to research the usefulness of the vaccine against oropharyngeal cancers.

    Yeah. Unprotected oral sex isn't safe sex. People really should be wearing condoms or using some kind of barrier when doing it but few people are going to actually do that.

    The lifetime risk seems to be around 1%, compared with an overall lifetime risk of cancer of over 40%. I don't think I'm going to worry too much.

    dang, 6 or more partners increases your likelihood up to 8 times. Guess I'd better keep my number of partners to 4 or 5, just to be safe!!

    This is why Gardasil (the HPV vaccine) is being recommended to boys too.

    EDIT: oops, it says so in the article too...

    Drinking hot tea may also cause throat cancer:

    http://oralcancernews.org/wp/study-links-drinking-hot-tea-to-throat-cancer/

    There have also been links to using mouthwash with alcohol and cancer, but the latest studies seem to have found no definite link.

    I'm just throwing this out there because there are a lot of possible causes of cancers, and some of them you can't avoid. I'm not advocating that people take unnecessary risks though. There are plenty of other reasons to be safe too.

    Anal sex can cause HIV/AIDS and, now, oral can cause throat cancer. It's a conspiracy, I tell ya! A conspiracy. icon_twisted.gif They'll do whatever it takes to keep a gay man down.

    One thing I've read is that you need to be more proactive to beat any cancer, and increasing your vitamin D intake will help do that. I'm not too sure if vitamin D would help with the HPV virus.

    That's why you gotta get your Guardasil shot!

    once again....

    Gardasil only protects against 4 HPV genotypes... genotypes 6 and 11, the two most common low-risk (wart-causing) HPVs and genotypes 16 and 18, the two most common high-risk (dysplasia/cancer-causing) HPVs. there are over 150 genotypes, so if you're already infected with any high-risk genotype other than 16 or 18, Gardasil is a waste of money. that's why it's best used in teens who haven't become sexually active yet. even then, it's not full protection against warts or cancer.

    And since HPV infection is a 'field' effect that starts the day you're born, you don't have to suck dick to get HPV in your mouth.... it gets in there through kissing, fingers and a host of other ways. same goes for your ass. sex DOES increase your exposure to more genotypes though, even if you're already infected from the 'field' effect of being human.

    I was wondering why they only recommended the HPV vaccine for younger people. I looked at the CDC website, but this was all I found:

    CDCWhy aren’t HPV vaccines recommended for people older than 26?

    Both vaccines were studied in thousands of people from 9 through 26 years old and found to be safe and effective for these ages. The FDA will consider licensing HPV vaccines for other ages if new studies show that this would also be safe and effective.


    Does anyone have any other information?

    Well I knew there were a ton of strains of it, but understood that Guardasil protects against the more virulent types.... I just love the idea of getting it through kissing and essentially being human..... So this is the part where we just accept the fact that life has risks to it and there are no guarantees? lol

    The other thing is that most HPV infections are cleared away successfully by the body.... I wonder what the research says about immunosuppressed people.... are they more susceptible etc.

    tumors caused by HPVs are always squamous cell carcinoma (SCC). SCC tumors of the cervix (uterus) and anus test positive for HPV genotypes 16 or 18 about 80% of the time, so these two genotypes do cause most SCC tumors. that's why they are in the Gardisil (and Cervarix) vaccines. of course, that means other HPV genotypes cause SCC as well.

    many HPV infections are 'suppressed' by the body. and yes, HPV infection is just a risk of being alive.

    HIV+ and other immunosuppressed individuals do tend to have more genotypes and tend to progress to dysplasia more rapidly than immunocompetent individuals, but i've seen some pretty serious dysplasia and SCC in HIV-negative individuals as well.

    @Rightasrain

    SO... how treatable are most squamous cell carcinomas? Assuming they are caught relatively early...

    SCC of the anus is still relatively uncommon... last statistics I saw suggested around 5800 annual cases with 770 deaths (http://www.cancer.gov/cancertopics/types/anal).

    it is curable if caught early, with chemo and radiation the usual treatments. surgical resection is also used in certain cases.

    we perform anal PAP smears on all patients in our practice (mostly gay males, 60-70% HIV+). the cells collected are examined under microscopy for abnormality and 'graded' on a scale created by the American Society for Colposcopy and Cervical Pathology (ASCCP). if the cells are concerning, we perform high resolution anoscopy (HRA) on the patient, biopsy the tissue as required and then remove the dysplasia (pre-cancerous changes) with heat through infrared coagulation (IRC). this way, we try to stay ahead of any dysplasia before it turns into SCC. this same process is used in females on the cervix of the uterus.

    there are a few threads on this in the forums.

    farah fawcett died of SCC of the anus that had spread throughout her body before her doctors found it. she could have been the 'poster gal' for anal cancer but we lost her potential message because she died on the same day michael jackson died. her story got 'lost' in the hooplah.
