Sobering news for rubber contraceptive users.

The Chemical and Veterinary Investigation Institute in Stuttgart said on Friday it had found the carcinogen N-Nitrosamine in 29 of 32 types of condoms it tested in simulated conditions.

The condoms, which were kept in a solution with artificial sweat, exuded huge amounts of cancer-causing N-Nitrosamine from its rubber coating. Researchers measured amounts of N-Nitrosamine, that were way above the prescribed limits for other rubber products such as baby pacifiers.

"N-Nitrosamine is one of the most carcinogenic substances," the study's authors said. "There is a pressing need for manufacturers to tackle this problem."

The study said that the carcinogen is thought to be present in a substance used to improve condom elasticity. When the rubber material comes in contact with human bodily fluids, it can release traces of N-Nitrosamine.

No immediate health risk

But since there are no prescribed limits of N-Nitrosamine for condoms, the study hasn't caused panic among manufacturers or mass-recalling of the products from counters.

Local government officials said condom users should not stop using rubber contraceptives based on the results of the study because N-Nitrosamine does not present an immediate health risk.

The Baden-Würtemmberg Social Ministry said it didn't think "it posed a risk." Authorities are also withholding the name of the affected manufacturers for fear of litigation.
Manufacturers should use alternative substances

But Germany's Federal Institute for Risk Assessment said that daily condom use exposed users to N-Nitrosamine levels up to three times higher than levels naturally present in food.

Werner Altkofer, head of the Stuttgart-based Chemical and Veterinary Investigation Institute said that though the production of rubber usually uses chemicals that can exude N-Nitrosamine, condom manufacturers could bypass it by using more expensive alternative substances available on the market that didn't form the carcinogen.

"We believe that it's up to the manufacturers to use other production processes so that no N-Nitrosamine is formed in condoms," Altkofer said.

He added that the latter was technically possible going by the fact that products of some manufacturers didn't show traces of the carcinogen during the testing.

Beate Uhse taking no chances

Germany's biggest erotica compnay Beate Uhse however, has decided to play it safe.

Shortly after the results of the study were introduced on Friday, the group banned chocolate-flavored condoms from its range. That was because the study had show that condoms laced with a chocolate flavoring had overwhelming high levels of N-Nitrosamine.

Condom Talc danger is very serious

ALL CONDOMS ARE COATED WITH TALC TO PREVENT THEM STICKING TOGETHER

Talc

Talc is a very fine substance, so fine it can be used as a "dry" lubricant.

Talc is a chemical similar to asbestos, a known cancer causing substance. Talc is found in many "baby and body" powders, feminine powders and many cosmetics. It's alsp used as a lubricant on condoms! While it makes your skin "feel" slippery smooth, talc does so much more.

How does talc keep babies and your private parts so "fresh"? Presumably by clogging the pores that secrete those necessary fluids. Also, those fine little particles manage to get into the system. And being similar to asbestos is not comforting, especially when used on babies and genital areas.

Talc's harmful effect on human tissues has been known for quite some time. Long ago, its dry lubricating properties were used as a glove-donning powder (easy to slide on) for surgical gloves. As early as the 1930's, talc was linked to post-operative granulomatous peritonitis and fibrous adhesions.

Talc...(on condoms)...may result in fallopian tube fibrosis with resultant infertility. Question raised by Doctors Kasper and Chandler in Journal of the American Medical Association. (JAMA) 3/15/95
-from Nutrition Health Review, Summer 1995 n73p8(1)

"A possible tie between talcum powder and ovarian cancer, long suspected because of talc's chemical similarity to asbestos, was strongly supported last week when a study found a higher risk of the cancer among women who used feminine deodorant sprays. The study, published in the American Journal of Epidemiology, found that women who used talcum powder in the genital area had an increased ovarian cancer risk of 60% and women who used feminine deodorant sprays had a 90% increased risk." In 1994, the FDA conducted a scientific workshop on the issue and did not find enough of a casual link to justify even a consumer warning.
-from The University of California, Berkeley Wellness Letter, April 1993 v9n7p1(2)

"Aluminum-containing antiperspirants are designed to be absorbed, and studies show that regular use of these products can raise the risk of Alzheimer's by as much as three-fold. (also)...municipal water supplies treated with alum (aluminum sulfate)...at least 7 studies show that people drinking water high in alum are more likely to develop Alzheimer's"

* Talc

This is found in baby powders, face powders, body powders as well as some contraceptives such as condoms. Talc is a known carcinogen and is a major cause of ovarian cancer when used in the genital area. It can be harmful if inhaled as it can lodge in the lungs, causing respiratory disorders.

Analysis Finds Link Between Talc Powders, Ovarian Cancer

By Eric Davis
WebMD Medical News

April 11, 2000 (Atlanta) -- For many women, a dusting of powder helps freshen the vaginal area. But a new study suggests that women should read the labels of so-called "talcum" feminine and bath powders closely. Cornstarch-based products may be better choices.

The study shows that powders can migrate from the vaginal area to the ovaries, and -- if the powder contains talc -- could slightly increase a woman's risk of ovarian cancer.

Slightly is the key word here. "Exposure to talc is unlikely to be a primary factor in most cases of ovarian cancer," writes John Whysner, MD, PhD, a researcher with the American Health Foundation in Valhalla, N.Y. He says there is not enough information to clearly say whether there is a causal relationship. Whysner reviewed over 50 papers on the subject, written over the past 30 years, for the analysis published in the American Journal of Obstetrics and Gynecology.

Talc is a mineral compound that is similar to asbestos; the two minerals are often found together in geological formations. In the past, some talc powders have been found to contain asbestos, but quality assurance programs have now minimized this contamination. The modest association between ovarian cancer and talc exposure found in some studies has been attributed to asbestos contamination, Whysner says.

Cornstarch, in comparison, is a food substance found in the corn kernel. Because of cornstarch's chemical nature, it is biologically implausible for it to cause cancer, he adds.

Whysner's review includes studies of more than 2,000 women with ovarian cancer who had used talc- and/or cornstarch-based products in the vaginal area. Some used the powder to dust sanitary napkins as well; some stored diaphragms or condoms in the powder.

Whether these powders can move through the fallopian tubes to the ovaries, where they might play a role in causing ovarian tumors, has been debated. In some studies, tubal ligation (having the tubes "tied") was linked with a decrease in the risk of ovarian cancer, Whysner writes.

"The risk for ovarian cancer was highest among women who used talc and had not undergone surgical sterilization," he says. He cites many studies in which the migration of particles through the fallopian tubes has been demonstrated. Both talc and asbestos have been found in human ovarian tissue.

Whysner writes that most studies have found that an increased risk for ovarian cancer is associated with exposure to talc power. "None [has] found an increased risk associated with ... cornstarch powders," he says.

Charles J. Dunton, MD, a professor of gynecology and oncology at Jefferson Medical College of Thomas Jefferson University in Philadelphia, tells WebMD, "There's not a cause for women to get overly upset if they've used talc in the past. The association is not that strong, and besides, it's all statistics, and there might be ... factors that cause the statistics to be inaccurate."

Also, because asbestos used to be found in talc powders, some of the early findings may be distorting the current picture, Dunton says. "Most of the baby powders now contain cornstarch rather than talc, but there are products like Shower-to-Shower that contain a lot of talc. ... Although the risk is very minimal, I would avoid talc in the [vaginal] area. That's the take-home message."

Ira Horowitz, MD, PhD, professor and vice chairman of gynecology/obstetrics and director of gynecologic oncology at Emory University School of Medicine in Atlanta, tells WebMD, "What I tell my patients is that there looks like there might be a causal relationship between talc and ovarian cancer ... [but] there's a lot we don't know."



Vital Information:

* A new study has shown that dusting the vaginal area with powders containing talc may slightly increase a woman's risk of ovarian cancer.
* Talc is a mineral compound similar to asbestos, and the two are often found together in geological formations, which might explain the increased cancer risk.
* Women should opt for cornstarch over talc powders. But there's no need to panic, as the increased risk of cancer is small, asbestos contamination is better controlled today than in the past, and the information on any association between talc and cancer is not complete.
