Thread: Oral Sex Is Leading Cause of Increasing U.S. Cancer Rates

Finding the source of cervical cancer offers hope to prevent and treat it...

Researchers find origin cells for cervical cancer
11 June`12 - Researchers have found the cells at the origin of cervical cancer, in a discovery that could offer new ways to prevent and treat the disease, according to a US-published study on Monday.

Most cases of cervical cancer are known to be caused by specific strains of human papillomavirus, but now researchers know the specific group of cells that HPV targets, said the study in the Proceedings of the National Academy of Sciences. Moreover, when they are removed from the cervix they do not appear to regenerate, said the study by scientists at Brigham and Women's Hospital, Harvard Medical School and the Agency for Science Technology and Research (A-STAR) in Singapore. The cells can become cancerous when infected with HPV while other cells in the cervix often do not, said senior author Christopher Crum, director of women's and perinatal pathology at Brigham and Women's Hospital in Massachusetts. They also have a particular gene expression that is the same as found in aggressive cervical tumors, which could allow doctors to differentiate benign lesions from dangerous pre-cancers.

"We have discovered a discrete population of cells that are located in a specific area of the cervix that could be responsible for most, if not all, of HPV-associated cervical cancers," said Crum, who was joined by researchers Wa Xian from A-STAR and Frank McKeon of Harvard Medical School. Michael Herfs, a postdoctoral fellow at Brigham and Women's, was the lead author. The cells are located near the opening of the cervix, in a transition area between the uterus and the vagina known as the squamo-columnar junction. The findings build on the group's previous research that identified the origin of a rare and sometimes cancerous change in certain cells in the esophagus, at a junction between the tube that carries food through the throat and the stomach.

A similar population of cells has been found to reside in the cervix, Crum said. They are the remnants of a process known as embryogenesis, which is the process of cell division and growth that we all undergo in the process of growing from embryo to fetus. "There is a population of cells in the cervix that during fetal life disappears and is replaced by another type. We found out that a small number of these cells are actually not lost and they remained there, almost like little sentinels from a prior age," Crum told AFP. "It appears that that particular group of remaining embryonic cells at the squamo-columnar junction is the population that you must infect, at least in the great majority of cases, to produce the significant cancers and precancers," he added. "During reproductive life they undergo changes, or metaplasia, when they become other cell types, so they are kind of like stem cells."

Knowing the biology of these cells and where they reside could help physicians both clarify which cervical precancers (dysplasias) need treatment and also possibly prevent cancer altogether by destroying the cells in advance. Further study may shed light on whether similar populations of cells reside in other areas of the body known to be affected by HPV-related cancers, such as the penis, vulva, anus and the throat. HPV types 16 and 18 are believed to be responsible for about 70 percent of all cases of cervical cancer in the world, according to the World Health Organization. While regular screening has drastically cut down on death rates in the West, cervical cancer continues to be a major killer of women in the developing world, and ranks as the third most common cancer among women globally. The WHO estimates nearly 530,000 women are diagnosed with cervical cancer annually worldwide and 275,000 die from the disease.

I should give it up then.

Oral Sex is Leading Cause of Increasing U.S. Cancer Rates, Compared to Tobacco Use in Other Nations

"Oral sex now leads the cause of oral cancer in America, according to a study.

Oral sex could be hazardous to your health. So say researchers who note that oral cancer stemming from the human papilloma virus is more common in the U.S. than oral cancer caused by abusing tobacco.

Researchers found a 225% increase in oral cancer cases in the U.S. from 1974 to 2007, mainly among white men, said Maura Gillison, a cancer researcher at Ohio State University.

The more oral-sex partners a man had, the greater his cancer risk, Gillison told a meeting of the American Association for the Advancement of Science.
Tobacco use remains the leading cause of oral cancer in the rest of the world.

There as many as 150 different types of human papilloma viruses, and about 40 of those can be sexually transmitted, according to the National Cancer Institute.

HPV infections often go undetected and are the main cause of cervical cancer in women.

Scientists are examining whether Gardasil and Cervarix, the HPV vaccines approved to prevent genital warts and cervical cancer, could have a significant impact on oral cancer.

In the meantime, researchers are urging doctors and educators to start talking to teens in particular about the risks of oral sex."

We all understand our main objections to abstinence, so the next best antidote for passing on the papilloma virus to others would be to have safe sex. But how safe is safe sex? Why ask me? I didn't write this article....

Anyways, the safest way to have sex is to have the male wrap their sexual organs in plastic, thereby enclosing the penis. The use of two (2) condoms instead of one is also a great idea, along with a signed affidavit of intent in case one partner unknowingly has the virus. When the male dons the 2 condoms over the plastic covering, they are now ready for safe sex....well, at least the female is.

All you horny pubescent males need to restrict your activities to a plastic- wrapped penis when approaching those horny nymphettes, and all you teen virgins need to stop oral sexing in order to save your virginity. Like, is this a contest between remaining chaste, papiloma virus, and abstinence, or what? Like, I say, NO...it should not be a contest at all, but one of a concept of no exchange of body fluids whatsoever.

This has been one of many lectures concerning the scariness of unprotected sex in the year 2011.

Garbage pseudoscience.

then you haven't been paying attention..almost .all the opposition to HPV vaccination has been morally/religious based....

in my city the public school board offered vaccination to all young girls before they become sexually active, this is no different than any other vaccination for communicable diseases...my girls have been vaccinated for polio, rubella, diphtheria a number of other diseases and now HPV, now the same vaccination program is being considered for young boys as well...the only schools not talking part are the religious ones as they claim it encourages sex...a completely deluded position as if religious oriented kids don't have sex...

You are basically saying that when it comes to public health, you don't have a choice what you do with your body!

Excellent point. I think I'll go and buy some nice marijuana now, to calm my ner....

Oh wait. The government seems to be telling me what I can and can't do to my own body in this regard.

When AIDS broke out I decided to stay in a monogamous relationship with one woman, and so far I've kept free of AIDS and all other STDs.

It's like I've always said, AIDS has done good things for this country.

Any law that forces the vaccination of an individual is a violation of the human right to control one's own body. There is no such thing as "public health" indepedent of "individual health." If I choose not to get vaccinated, then I must accept the consequences that may arise as a result. Likewise, people make a choice to give oral sex to stranger who may have certain diseases. If they are not certain the person has been vaccinated, it is their choice to have sex with them anyway.

I am not religious, I am not against oral sex, and I think that it would be wise for people to get vaccinated against these diseases. But I also understand that I have no right to control the lives of others against their will.

ya we do, no one has the right to recklessly spread deadly diseases among the population, small pox, ebola, polio, sars, plague are deadly killers...knowingly doing so is the same as walking around randomly firing a loaded gun in public spaces killing people...already there has been a murder conviction for a man with HIV who had sex with two women killing them...your freewill ends when your behaviour endangers others right to life...

Women who have not yet been vaccinated against these infections are not harming anyone by declining to receive such vaccinations. You are criminalizing women before they even have a chance to act

The harm is inflicing during the act of sex by the individual with the disease. There is no harm inflicted on anyone when a healthy woman refuses a vaccination.
