What causes skin cancer?
-
Skin cancer develops in the cells in your skin. Normally, these cells go through a growth cycle in which old cells die and are pushed out by new cells continuously. In skin cancer, the DNA that controls that growth cycle is damaged, most commonly by ultraviolet radiation from the sun. This causes an overgrowth of cells, which eventually builds up and forms a tumor. The type of skin cancer you have depends on the type of cell that is affected, but all types of skin cancer begin in the epidermis (the topmost layer of skin).Skin cancer develops in the cells in your skin.

Damage in the epidermis to the normal DNA of skin cells may result in new cells growing out of control, and eventually forming an accumulation of cancer cells.
UV light: The ultraviolet (UV) radiation in sunlight and commercial tanning lamps and beds may cause DNA damage that can lead to skin cancer. UV light is divided into three wavelength bands, including ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). Only UVA and UVB rays reach the earth. UVC radiation is completely absorbed by the atmospheric ozone. UVA and UVB rays play a role in the formation of skin cancer by causing changes in skin cell DNA, including the development of oncogenes, which are types of genes that can turn a normal cell into a malignant one. UVA penetrates the skin more deeply than UVB.
Tanning beds deliver high doses of UVA, which makes them especially dangerous. UVA puts an individual at greater risk of skin cancer than spending long hours in the sun because of the deep penetration of the rays.
Genetic predisposition: Although most cases of skin cancer are related to environmental factors, such as UV exposure, genetics may also play a role. Some people, especially those with fair skin that freckles easily, may be genetically predisposed to developing skin cancer. Therefore, having a family history of skin cancer may increase the risk of developing the disease.
Other factors: Exposure to toxic chemicals and radiation treatments may also cause skin cancer.You should read product labels, and discuss all therapies with a qualified healthcare provider. Natural Standard information does not constitute medical advice, diagnosis, or treatment.
