BP causes cancer?

Recommended Posts

From http://www.bion-research.com/valuable_acne_tips.htm

Benzoyl Peroxide Cautions: Benzoyl peroxide (BP) generates free radicals in the skin. Its effect is similar to unprotected sun exposure. The redness of the skin (erythema) caused by the sun and BP is the result of free radicals (oxidative stress) upon the skin. Repeated sun exposure and BP use generates free radicals that damage the skin's structure and cellular DNA, resulting in premature aging of the skin. The extent of the damage and aging from BP is determined by the concentration of BP, the frequency of applications and the duration of its use. Non-medical skin professionals should no knowingly damage skin or promote its premature aging.

Because benzoyl peroxide generates free radicals it interferes with and slows the healing process. The red and brown marks that are a part of the acne healing process may last weeks longer when BP is a regular part of the daily regimen.

Benzoyl peroxide has been linked to cancer for a number of hears and many research journal entries state "benzoyl peroxide is a free radical-generating skin tumor promoting agent." Performing a word search of the words "benzoyl peroxide cancer" in PubMed in the National Library of Medicine produces 102 articles from medical publications dealing with research aspects of BP and cancer. About two-thirds of the research supports linkage between BP and cancer.

Skin care professionals are reminded, "In 1995 the FDA changed benzoyl peroxide from a Category I (safe) to a Category III (safety is uncertain) ingredient and stated this action (56 FR 37622) was based on new information that raised a safety concern regarding benzoyl peroxide as a tumor promoter in mice..." Additionally, the FDA charged manufacturers with the responsibility of providing this information to consumers so they could make educated decisions. A more complete FDA statement is at the bottom of this page for your reference.

Use of BP to control or maintain the control of acne may promote severe skin damage. Aestheticians selling benzoyl peroxide products should advise the client of the potential of premature skin aging, skin cancer or the potential of developing benzoyl peroxide-induced eczema from BP contact dermatitis. BiON has given particular attention to providing effective treatment with no side effects and does not use benzoyl peroxide

What doesn't cause cancer thesedays? :rolleyes:

Seriously, it was the last damned straw when I heard drinking from aluminium cans can cause cancer.

BP has been shown to be a tumor promoter at high concentrations in mice, but not a tumor initiator. In those experiments they use a high concentration of BP on SENCAR mice (mice that are basically bred to be very likely to get cancer in a lab setting) and then have to use UV rays or a chemical called DMBA to actually cause the tumors to develop. No studies have ever shown that BP can promote tumors in humans, either, and in surveys of people with skin cancer on their faces, they did not find that rates of benzoyl peroxide use to control acne were any higher in that population than in a control.

I only read the word cancer or skin cancer. I would assume that it would be more towards skin cancer since it would make the skin more vulnerale in the sun being that the sun is more what causes skin cancer. Just as it does premature aging...so yeah, use a SPF!

I know that my derm doesn't like benzoyl peroxide because she says it solves one problem but gives you another cos benzoyl peroxide slows down healing. However, benzoyl peroxide seems to be the mainstay for acne treatment.

It causing skin cancer is like the secondary problem. I know it increases the risk of sunburn. But shouldn't everyone know that without using SPF in the sun or going tannng frequently just makes you more liable to skin cancer? Doesn't mean that you don't use benzoyl peroxide means you won't get skin cancer. Just doesn't make sense. Whatever it is, whether you get skin cancer or not, its up to the individual to whether he wants to protect himself on not. Don't blame it on the products.
