Moles And Uv Radiation
This is light of extremely short wavelengths typically produced either among the stars / in cosmic rays or by radioactive element decay. Gamma rays form the background of normal radiation in which we all live; it is substantially greater than the exposure we get from imaging scans or should get from ...Read more
If moles are full of melanin, does that mean an existing mole if exposed to uv radiation won't turn to melanoma?
No, risk remains: 'moles' on the skin are nevi, essentially benign but abnormal collections or growths of melanocytes in the dermis (the layer just under the epidermis) and sometimes also in the epidermis. Uv light damages the dna in cells and when it does so in melanocytes in nevi they may be transformed into melanomas. The pigment does not protect the cells. ...Read more

Lack of uv light between 270 and 300nm stops vit d production. Can the lack of a certain wavelengths of radiation stop a cancer cells growth?
No: Please forgive my frankness. If somebody tells you otherwise, they are lying. This is as biologically preposterous as the idea that limiting certain wavelengths would end a pregnancy. Certain wavelengths of light catalyze conversion of vitamin D precursors to the real thing. Cancer is almost-healthy cells gone bad. ...Read more
UV: Neighter.Get a more detailed answer ›
No: Long term exposure to uv light is unhealthy. However, we need some uv light from the sun to produce vitamin d. Vitamin d is important in regulating bone density and osteoporosis. Vitamin d deficiencies have been linked to tooth loss, and periodontal risk factors like low bone mass. Also vitamin d may act as an anti inflammatory agent and stimulate the production of oral anti microbial peptide. ...Read moreSee 1 more doctor answer
They make sunglasses that block ultraviolet rays. Would you buy a screen to tan under that blocked ultra?
No: If such a screen really blocks all the ultraviolet then you wouldn't tan! tanning is a reaction of your skin to the damage that ultraviolet radiation causes. The cells of the skin put up little screens that try to shield the nucleus from further injury. Around 20 minutes of sun exposure a day can make your vitamin d ration. Otherwise, try to limit your exposure. ...Read more
