Sun blocks could cause cancer, but …

International studies are finding a correlation between sun blocks and skin cancer, though not in the beneficial preventative sense as one would expect. The emerging argument is that sunscreen may in fact be a cause of skin cancer, not a cure.

These findings are somewhat unnerving and sobering, as males and females of all ages, especially women, have been told for years that the use of sunscreen will prevent skin cancer and premature ageing of the skin, such as wrinkles.

Dermatologist Lawrence Scerri told MaltaToday: “there is a very small theoretical risk of sunscreens causing skin cancer, but the risks are completely outweighed by the benefits of sunscreen which help prevent skin cancer.”

The arguments behind the so-called deadly effects of sunscreen are varied, but predominantly revolve around the inhibition of vitamin D production.

The background story: Sunshine serves a very important function in the body, triggering the production of vitamin D. This helps protect the body against at least 25 chronic diseases, namely osteoporosis; different cancers, such as breast, kidney, and prostate cancer; heart disease and also schizophrenia.

Through the use of sun block, vitamin D is not produced, creating a vitamin deficiency.

According to naturalnews.com, recent research conducted in the UK found another reason backing the argument that sun block causes skin cancer. The product often contains toxic chemicals in the form of chemical colours, artificial fragrance, and petroleum products which are used as fillers and stabilisers. When applied to the skin, the chemicals are absorbed into the bloodstream and upset the immune system. Of particular hazard are artificial fragrances, which contain cancerous chemicals, according to the study.

However, not everyone agrees.

“To date, there has been no statement or recommendation issued by either the World Health Organisation, the European Commission in Europe, or the Food and Drug Administration in the United States to this effect,” Dr Scerri said.

According to the LA Times, many sunscreen manufacturers are inflating the Sun Protection Factor (SPF), giving the impression it offers invincible protection. However, the same newspaper said an SPF of 15 blocks 94% of UVB rays, while SPF 30 and SPF 45 blocks 97% and 98% respectively.

In response to this, Dr Scerri explained “It is normally recommended that people opt for the higher level of sun protection factor; however, whatever the SPF, it is just as relevant to use the sunscreen at all times and applied repeatedly.”

Before binning every sunscreen product available at hand, it is significant to keep in mind that the products have been proven to prevent sunburn, which is damaging in itself, and skin cancer. Before there is solid reason to believe otherwise, it is therefore highly recommended to keep applying sunscreen.
