Sun, tanning lamps suspected in
rise in melanoma
Actress Sarah Paulson was diagnosed with melanoma on
her back but doctors removed it and found that it had not
spread. [4]
A lady prefered the bronzed look, she went under the lamps of a
tanning salon two a week for six years then she found skin
damage and freckles under her eyes. [1]
A study led by Mark Purdue of National Cancer Institute,
published in July 2008, examined melanoma incidence between
1973 and 2004, and found the rate jumped by 50 percent since
1980 for women between the ages of 15 and 39. For men of the
same age, the rate remained stable.[1]
Women are more likely to visit indoor tanning salons then men
making them more prone to risk. [3] A combination of excessive
sun exposure and the possible overuse of tanning salons may
tend to cater more to women than to men. Tanning beds emit
ultraviolet rays that can damage the skin the same way that the
sun can.[1]
Melanoma often first appears as a harmless mole, though it has
a notorious potential to spread.[1]
We can reduce the general risk of developing melanoma by
avoiding sun exposure when the sun's rays are strongest,
between 10 a.m. and 4 p.m.; wearing protective clothing and a
sunscreen with an SPF of 15 or greater; and not actively seeking
a tan in the sun or a salon. [4]
What is melanoma?
Melanoma is a malignant tumour derived from melanocytes
(dendritic cells originated from the neural crest and capable to
produce melanin synthesis) that could be established on the skin
or less frequently on the uvea. The cellular origin from both kind of
melanoma seems to be the same but the melanocytes migrates
to the epithelia for cutaneous melanoma, while for uveal
melanoma, they migrate to mesodermic tissues. [2]
The National Cancer Institute estimates 62,480 new melanoma
cases will be diagnosed in the United States in 2008 and 8,420
will die from the disease. [3]
