Yes, I've heard of anal cancer. Half my family are doctors. And that is what the author of this article is clearly not.
So the risk of anal cancer is 40 times higher - but it's still pretty low, also in comparison to other, more common cancers (lung, breast, colon etc.).
Take another example: The common treatment for autoimmune diseases (like Multiple Sclerosis, Myasthenia gravis etc.) is immunosupression. With that, your cancer risks go through the roof, the risk for skin cancer is probably a few hundred times higher. But that doesn't mean the treatment is wrong, because everybody will get cancer. In fact, still very few do.
Bottom line: If your argument is epidemiology, you should know what you're talking about. It's annoying how nowadays everybody pretends to be an M.D..
Did I insult your intelligence? I'm sorry to offend you, because clearly you are deriving all your information from riding the coattail of all the Doctors in your family.
I don't agree with the article's suggestion to classify homosexuality as a disorder. I just found it informative for those of us who don't have a family of "Doctor's". It is information that I thought needs to be out there. If I told you not to do something because you could die from it, wouldn't you want to know what the consequences are. It doen's t mean you won't engage in it but you can't claim ignorance.
However, the article is written by a Nurse who worked with several who claimed to be homosexual and the original writings were by several Doctors involved with the research. (See the names below original document.)
Anal cancer, does occur because one engages in homosexual encounters. Yes, there are many diseases and cancers you can get. The point is, this particular one can be prevented by not choosing the homosexual lifestyle. Don't you think that information needs to be out there? Does your family of Doctor's explain the health risk associated with the homosexual lifestyle besides just AIDS/HIV?
