Development and growth of skin cancer may be affected by various physical and chemical factors present in human environment. Of these factors electromagnetic radiation of radio- and microwave spectra are among the most common.
Radiation Exposure and Cancer

Radiation is the emission (sending out) of energy from any source. The light that comes from the sun is a source of radiation, as is the heat that is constantly coming off our bodies. When talking about radiation, however, most people think of specific kinds of radiation such as that produced by radioactive materials or nuclear reactions. Most forms of radiation have not been linked to cancer. Only high frequency radiation (ionizing radiation and ultraviolet radiation) has been proven to cause genetic damage, which can lead to cancer.

The hazards of exposure to some kinds of radiation were recognized shortly after the discovery of the x-ray in 1895. Skin reactions were observed in many people working with early x-ray generators, and by 1902 the first radiation-caused cancer was reported in a skin sore. Within a few years, a large number of such skin cancers had been observed. The first report of leukemia (a cancer of the bone marrow) in radiation workers appeared in 1911. Marie Curie, the discoverer of radium, and her daughter are believed to have died of radiation-caused leukemia. Since that time, many studies have confirmed the cancer-causing effects of some types of radiation.
