Sunblock Does Not Stop Skin Cancer

In this article Dr. Mercola suggests the only way to avoid skin cancer is to gradually introduce your skin to the sun and always avoid getting burned. Please read his comments below, thanks Sarah.

Sunscreen does not protect against melanoma, the most dangerous form of skin cancer, according to researchers. Although the lotions decrease the risk of sunburn, they do not block UVA rays, which cause melanoma.

Researchers found that even sunscreens with the highest protection factor of 35, applied in the correct amounts, were not effective at filtering out the harmful rays. They say that people should limit their sunbathing time and use clothing to block UVA rays when sun is at its strongest.

Dr. Mercola's Comments:

As I said in July sunblock can actually increase your risk of skin cancer. Although most sunblocking agents seem to prevent burning, they are not very good at blocking the UVA that causes skin cancer. Unfortunately, they are effective at blocking UVB, the wavelengths our bodies need to produce vitamin D.

With the negative spin that sun exposure has gotten from the media, you may be tempted to avoid the sun completely. But remember that we ALL need sunshine to stay healthy. Exposure to the sun provides many benefits such as promoting the formation of vitamin D and fighting depression.

Can sun exposure cause skin cancer? Absolutely.

However, there is strong evidence that suggests sunlight is protective against MS and breast, colon and ovarian cancers.

This does not mean that we should all go out and get as much sun as we want--you must exercise caution. At the beginning of the season, go out gradually and limit your exposure to perhaps as little as 10 minutes a day. Progressively increase your time in the sun so that in a few weeks, you will be able to have normal sun exposure with little risk of skin cancer.

Remember to never get burned, that is the key.

Using sunscreen is not a good way to limit your sun exposure; in fact, sunscreen is one of the LAST things you want to put on your body. Sunscreen is a toxic chemical that can cause problems in your system and increase your risk of disease.

A far more logical solution would be to creatively use your clothing to block the sun’s rays during your build-up time.

Additionally, consuming many whole vegetables will increase antioxidant levels in the body, which will provide protection against any sun-induced radiation damage.
