　　The trend is particularlysince younger people are not generally those most susceptible to melanoma. Rates of skin cancer arehighest in people over age 75.

　　But experts worry that increasing numbers of younger people being diagnosed with skin cancer could be theof a dangerous trend. Womentheir 20s make up a small percentage of all patients diagnosed with melanoma in Britain, but nearly a third of all cases occur in people younger than 50.

　　Based on current numbers, Cancer Research UK predicts that melanoma will become the fourth most common cancer for men and women of allby 2024, and that cases will jump from about 9,000 cases a year to more than 15,500.

Spending time on sunbeds is just dangerous as staying out too long in the sun, said Caroline Cerny of Cancer Research UK. The organization is starting a SunSmart campaign to warn Britons of theof being too bronzed.

　　The intensity of UV rays in some sunbeds can be more than 10 timesthan the midday sun, Cerny said.

　　In the United States, several states require parental approvalminors can use tanning salons. Wisconsin bans people 16 and from using tanning beds, and others ban children under. 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 hasnt yet been implemented. There are no plans for 14 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 if people took the proper precautions when in the sun and avoided tanning beds.
