BEIJING,
Oct. 30 -- It's autumn in Hong Kong but the island's beaches are still crowded
with sun worshippers desperate to catch the last rays of sunshine before winter.
"I love the bronze color," says sunbather Richard
Tong.
A growing trend in East Asia to soak up the sun
either on beaches or in tanning salons is worrying dermatologists in the region
who say they are seeing a rise in skin cancer, which is caused by cumulative
over-exposure to the sun.
The number of cases is low but the tanning trend has
raised concern of cancer risks in a region where a porcelain complexion was
traditionally considered the ultimate sign of beauty and refinement.
"Asians, including South Koreans, used to think they
were pretty safe from skin cancer. However, due to increased outdoor activity,
more (sun) exposure and sun tanning, there is an increasing incidence of skin
cancer amongst younger people," said Ro Young-suck, head of the Korean
Dermatologist Association.
"There has been a huge increase in skin cancer rates
in Korean men in particular. We predict it's because while most Korean women
usually wear sunscreen while putting on their makeup, men aren't used to this,
aren't aware how dangerous it is, and so they don't bother to."
While incidences of skin cancer in most places in
Asia are small compared to the United States and Australia, the number of cases
have jumped markedly in recent years.
There were 1,712 new cases of skin cancer diagnosed
in South Korea in 2005, up from 777 in 1995, according to the Korea Central
Cancer Registry. Incidences in Hong Kong went up to around 650 in 2004 from 370
in 1995.
"People who are constantly exposed to UV (ultraviolet
radiation in sunlight) won't get cancer immediately," said George Li, a plastic
surgeon at Hong Kong's public Queen Mary Hospital.
"It takes a long time to cause skin damage, as people
get older there is a high chance to develop skin cancer."
Skin cancer is one of the commonest forms of cancer
and is linked to other risk factors like fair skin, light colored hair and eyes,
a compromised immune system, genes and old age.
There are three major types of skin cancer: Basal
cell carcinoma, squamous cell carcinoma and melanoma. The first two are slow
growing and highly treatable if discovered early.
Melanoma is the most lethal. It affects deeper layers
of the skin and can quickly spread to other parts of the body. It causes 8 out
of every 10 skin cancer deaths in the United States.
Caucasians are more susceptible to skin cancer and an
average of one in three Caucasians gets skin cancer in their lifetime, according
to the US Skin Cancer Foundation.
