Cancer Causes

[Michaelangelica]

Well we have cancer cures do't we?
I guess there are alot of things in the 'maybe class', some we don't know yet.
it would be nice if we cauld back up cancer causes with as much good research as possible.Cancer Causes in all mammals is acceptable.

However to ' 'fes up' I started this thread so i would have somewhere to put this bit of serindipodus reseach

Common commercial skin care products may increase users' risk of contracting skin cancer, according to a paper by researchers from Rutgers University and published in the Journal of Investigative Dermatology.

Researchers had originally been planning to study whether topically applied caffeine could reduce people's risk of skin cancer.

"We sort of got into this by accident," researcher Allan Conney said. "We wanted a safe cream that we could put the caffeine into."

The test was to be carried out on albino mice, which are specially bred to be predisposed to skin cancer. In order to simulate the condition of a person who has only recently become aware of the risks of skin cancer but who got lots of sun exposure previously, the researchers bombarded the albino mice with ultraviolet radiation before the study began.

The researchers intended to apply the caffeine by dissolving it into a skin cream, but first wanted to make sure that any cream they used was actually neutral for skin cancer risk. So they applied four commercially available creams to the mice, and discovered that all of them increased the mice's risk of developing skin tumors known as squamous cell carcinoma.

Squamous cell carcinoma is more slow-growing and substantially less lethal than the less common melanoma. Most cases of squamous cell carcinoma can be easily removed without risk to the patient if they are detected and acted on early enough.

The experiment could not determine which ingredients of the skin creams might be causing cancer, but Conney suspects that mineral oil might be responsible, as might sodium laurel sulphate.

"We'd like to understand the mechanism," Conney said. "What is most important is to see whether these moisturizing creams are tumorigenic in people."

New Study Shows Skin Cream May Cause Skin Tumors

Tumorigenic Effect of Some Commonly Used Moisturizing Creams when Applied Topically to UVB-Pretreated High-Risk Mice

The results indicate that several commercially available moisturizing creams increase the rate of formation and number of tumors when applied topically to UVB-pretreated high-risk mice. Further studies are needed to determine the effects of topical applications of moisturizing creams on sunlight-induced skin cancer in humans.

Coming straight from the research labs of Rutgers, a study was published in Journal of Investigative Dermatology stating that some skin moisturizers may increase the chances of getting a type of skin cancer called squamous cell carcinoma.

The mechanism behind the cancer inducing effects of moisturizers are unknown, and the carcinogenic ingredient(s) are also undiscovered. But scientists suspect mineral oil and sodium laurel sulphate, two common additives in moisturizers.

Interestingly, Rutgers and Johnson & Johnson have already come up with a patented kind of moisturizer that contain no mineral oil or sodium laurel sulphate.

What are the chances!?
I didn't see this article when I first started to post.

"I disagree with the article," Dr. Margaret Ravits said Thursday. "I've been in practice 30 years, and we don't find any problem with using moisturizers.

even for those people who do not use skin creams, sodium laurel sulphate is the foaming agent in shampoos and liquid body wash. Also commonly used is ammonium laurel sulphate in these products. Your skin is getting a heaping dose very time you bathe and wash your hair. Some toothpastes contain this as well.

Somehow, this isn't surprising. btw, don't rule out the possibility that chemicals in the creams may react with UV radiation in sunlight, environmental factors or exposure, or other chemicals, and thus form carcinogenic by-products.

Although not related to skin creams directly, I found out recently that triclosan, used in many anti-bacterial soaps and hand cleansing creams, can react with UV light or from other sources to form dioxins, among some of its by-products. Think about that. Hmm.
