     Melanoma (黑素瘤), the deadliest kind of skin cancer, is now the most common cancer in【51】British women, the country’s leading cancer organization said Wednesday. Skin cancer has【52】cervical (子宫颈的) cancer as the top cancer striking women in their 20s, according to the latest data from Cancer Research United Kingdom.
    The trend is particularly【53】since younger people are not generally those most susceptible (易患的) to melanoma. Rates of skin cancer are【54】highest in people over age 75.

"Spending time on sun beds is just as【59】as staying out too long in the sun," said Caroline Cerny of Cancer Research UK.

    In the United States, several states require parental approval【62】minors can use tanning salons. Wisconsin bans people 16 and【63】from using tanning beds, and others ban children under 14. At least 29 states have regulations governing minors’ use of tanning salons.
     In the U. K. , Scottish politicians passed legislation banning those under 18 from using tanning beds, though it hasn’t yet been implemented. There are no plans for【64】in the rest of the U. K.
     The World Health Organization has previously recommended that tanning beds be regulated because of their potential to damage DNA in the skin.
     Experts said most deadly skin cancers could be【65】if people took the proper precautions when in the sun and avoided tanning beds.
