Melanomais the sixth run cause of cancer in the U.S. , according to the American Cancer Society . About 76,000 cases of melanomas will be diagnosed this yr , ground on recent estimates .
In the study , researchers examined about 69,000 adult male and fair sex , and after about six year , 566 had uprise melanoma .

Study research worker Dr. Maryam Asgari , a skin doctor and research scientist at Kaiser Permanente in Oakland , say the protective core might be stronger in women than men because men may be moresusceptible to skin damagefrom ultraviolet radiation .
She indicate to a late animal study that suggests females may have more natural antioxidant protective covering in the pelt than Male .
The novel subject area also found the melanoma jeopardy was shorten the most in those who take on high Zen of the supplement . But Asgari cautioned that taking too much vitamin A could lead to such harmful conditions as birth defects , liver problems and os loss .
" There are limits to how much vitamin A a mortal can consume , " she said .
The recommend everyday amount of vitamin A is 700 micrograms for grownup women and 900 mcg for grownup men , according to the National Institutes of Health . Taking more than 2,800 micrograms of vitamin A could direct to toxic symptom in adults .

Unfortunately , not all melanoma is a result of sunshine pic . There is also a solid genic component , Mercurio read . " Even the most vigilant sun - avoider is at risk , especially if they are fair - shinny , freckle well and have crimson or blonde hair . "
Although she said the study ’s determination were compelling , she cautioned it ’s not clean-cut how much vitamin A might bring a benefit .
