I was just wondering, can anal sex cause colon cancer or any other type of cancer? I have heard that doing it alot can cause it?

Unless there are other factors (like contracting an STD anally) then no, it doesn't make you more likely to have colon cancer.

Family history of cancer, personal history of colon cancer, diseases that cause chronic inflammation or ulcers, and certain genetic conditions are the main precursors to colon cancer.

The National Cancer Institute lists anal sex as a risk factor for anal cancer.

I'm guessing that the NCI knows what they are talking about.

I believe, as a prior poster said, that any increased risk for cancer would be mediated by an STD, such as HPV (human papilloma virus), which could be contracted through anal sex and is a well-recognized risk factor for cancer.

Of course, HPV can be contracted through vaginal sex,and is also associated with cervical cancer. So by that line of argument vaginal intercourse 'causes' cervical cancer.

Weird fact: Gay men have lower incidences of prostate cancer due to their anal sex activity. Massaging the prostate is good for the body and decreases your risk for that type of cancer.

I have waaay too many stories about anal warts, dysplasia, and rectal cancer then I care to share. If you are concerned, please ask your doctor about getting a anal pap smear.

Their colon cancer listing doesn't mention anything about it. I'm guessing the anal/rectal cancers stem from dysplasia due to either STD's or inflammation.

<channeling Jack Nicholson as Joker> This whole thread needs an enema!

It can cause some 'roids.

Anal warts can be caused by anal sex...even protected anal sex. Condoms really only cover a certain amount of area, and if you have HPV down by the base of your penis or close to your scrotum, that can definately come into contact with whomever you are having sex with.

If gone untreated or undetected, HPV can change into dysplasia which can then turn into cancer. The same can happen in a women's cervix which can also cause infertility.

This is why you should ask about getting an anal pap smear if you happen to routinely engage in receptive anal sex.

As far as I am aware, you can not get anal cancer if both you and your partner are STD free and engaging in anal sex.

I believe I just saw a headline that claimed, "Cancer linked to Masturbation"

Not sure of the exact wording, but that's the idea. So if not even masturbation is safe...I protect myself in all activities (of course it helps a lot that I have been in a monogomous (spelling?) happy marriage for 5 years), but I also enjoy life.

I read that. It was a study linking increased masturbation by men to increased risk of prostate cancer. Interestingly enough, this contradicts another recent study that claimed frequent masturbation decreased prostate ca risk. Bottom line.....researchers often don't know what in the hell they're talking about.

Amen to that!!!!!

That study was probably the same study that claims fat people have infectious fat cooties.

So if someone could explain to me why they like anal sex, I would greatly appreciate it. I don't see how it could be enjoyable. I know people say if they relax it is enjoyable, but how is it possible to have an orgasm that way? There isn't anything in the anus that would cause an orgasm. I am confused.

I have shot my load plenty of times when having oral sex. It was the best that I have ever cum

So am I. :w00t:

I believe if you think about simultaneous stimulation you'll connect the dots.
