Riscul de cancer cutanat a crescut cu 10% din cauza radiaţiilor de tip C

"gena expusa la soare" este o exprimare absolut aberanta, iar deocamdata ultravioletele de tip C nu patrund in piele, atat cat stiinta a putut dovedi. Nu se cunoaste in dermatologie patologia indusa de UVC, radiatiile cu lungime de unda intre 0 si 100 nanometri. De unde scoateti toate aceste absurditati?

Ma ocup de EDUCATIA SI PREVENTIA CANCERULUI, inclusiv a CANCERULUI SPIRITUAL pentru a aduce la lumina FAMILIA ROMANEASCA SI SCOALA ROMANEASCA. « Melanoma is a malignant tumor of melanocytes. The tumors are generally found in the skin, but may also appear in the bowel and the eye (uveal melanoma).melanoma is a type of skin cancer –one the rarer types - but the cause of most skin cancer related deaths. Malignant melanoma is caused by an uncontrolled growth of skin pigment cells (melanocytes). The word « melanoma » comes from the Ancient Greek « melas » meaning « black » , and the Ancient Greek « oma » meaning « disease, morbidity ». What is the difference between skin cancer and melanoma ? Melanoma is a type of skin cancer. Imagine the words « bananas » and « fruit ». All bananas (malignant melanoma) are fruits (skin cancers) , but not all fruits (skin cancers ) are bananas (malignant melanomas). There are three main types of skin cancers : a) Basal Cell Carcinoma ; b) Squamous Cell Carcinoma ; c) Malignant Melanoma. What causes malignant melanoma ? Experts say that over-exposure to sunlight is the main cause of malignant melanomas. Sunlight has large amounts of radiation in the form of light and heat. The atmosphere of this planet filters out most of the harmful effect of this radiation. Two radiation wavelengths , however , still get through and hit our skin – UVA (ultraviolet A) and UVB (ultraviolet B). UVA is one that causes mutations in our melanocytes. Melanocytes produce melanin ; a substance that gives color to our skin.If the melanocytes become mutated (their DNA alters) melanomas can develop. UVB can also cause other non-melanoma types of skin cancer. Artificial sunlamps –those found in tanning beds –also produce UVA.If they are used excessively they can increase a person’s risk of developing melanomas ».

Les Français disent : « Le soleil brille pour tout le monde ». « UV radiation : Ultraviolet radiation. Invisible rays , that are part of the energy that comes from the sun, can burn the skin, and cause skin cancer.UV radiation is made up of three types of rays – ultraviolet A (UVA), ultraviolet B (UVB) and ultraviolet C (UVC). UVC is the most dangerous type of ultraviolet light but cannot penetrate earth’s protective ozone layer.Therefore , it poses no threat to human, animal or plant life on earth.UVA and UVB , on the other hand , do penetrate the ozone layer in attenuated form and reach the surface of the planet.UVA is weaker than UVB but passes further into the skin than UVB. It is now generally accepted that both UVA and UVB cause skin cancer, including melanoma. For this reason , sunscreens are recommended that block both kinds of radiation –UVA and UVB. In addition to natural light from the sun artificial light from tanning lamp contain UVA and UVB.Electric arc lamps can also generate ultraviolet light to heat furnaces for melting and to enable motion- picture projectors to show movies. Though ultraviolet light can damage health, it can also maintain or improve health. When ultraviolet light strikes human skin, it triggers the production of vitamin D, which promotes the growth of bones and teeth. SOURCE : Medicine Net. »
