Skin Cancer in Australia
3010 Words | 7 PagesSkin cancer is a significant public health issue in Australia. Exposure to ultraviolet radiation emitted by the sun in the UVA and UVB wavelengths is the primary cause. Australia has been a world leader in efforts to protect the ozone layer, the main line of defense against ultraviolet radiation emitted by the sun. Ultraviolet radiation induces the formation of thymine dimers that cause mutation of skin cells if not repaired before DNA replication. Mutations of tumor suppressor genes can lead to uncontrolled cell growth. Ultraviolet radiation also causes immunosuppresion that allows skin cancers to become established. Basal cell carcinoma, squamous cell carcinoma, and melanoma are types of skin cancer caused by sun exposure, though each form is associated with a different pattern of exposure. Australia has the highest rate of skin cancer in the world, due to a combination of tropical latitude, fair-skinned population, outdoor lifestyle, and high amount of ambient ultraviolet radiation. Widespread opinions about tanning and health benefits of sunlight lead many Australians to intentionally overexpose themselves to the sun. State cancer councils have developed sun safety and awareness campaigns, such as “Slip! Slop! Slap!” and “SunSmart,” to educate the population about sun exposure and encourage early detection of skin cancers. Gradual changes in knowledge and behavior indicate that the fight against skin cancer can be won.

Ultraviolet A rays are the longer ultraviolet rays that are projected, and these rays penetrate deep into the layers of skin, causing a tanning effect (Harvard Women's Health Watch, 2). It does this by penetrating into the lower layers of skin, or the epidermis, and triggering cells known as melanocytes to make melanin, the brown pigment that causes tanning (Hyde, Patrice, MD, 1). They account for most of the ultraviolet components emitted by lamps in tanning beds, because they are associated with an almost immediate tanning effect (Brady, Mary S, 2). The shorter rays are ultraviolet B rays, and these rays only reach the outer superficial skin cell layer, also known as the epidermis (Harvard Women's Health Watch, 2). UVB rays, therefore, are the actual cause of sunbur...
