Sunblock Does Not Stop Skin Cancer

October 20, 2003

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 Comment:

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.
