In recent years, we have seen more and more skin cancer pictures as the disease has become a topic of popular conversation. As incidences of skin cancer increase around the world, particularly in societies where there is a lot of sun exposure such as Australia, we are becoming more aware of how this disease can threaten lives. This article provides general information about the signs of skin cancer.
The background to the problem
While it is almost assuredly true that cancer has always been and will always be a part of human society, in medical developments within our lifetimes we have become aware of cancer risk factors. With our increased understanding of the disease, we are able to comprehend how and why it forms.
Skin cancer in particular can form as exposure to ultraviolet radiation has the potential to cause mutations in the DNA of the skin cells. These mutations can create cancerous cells which then begin to multiply and take over the host body.
The hole in the ozone layer
The ozone layer acts like a shield around the earth, but in some places (particularly over Australia and the Poles) a real hole has developed.Because of human pollution, more radiation is coming down onto the planet than in earlier times. During the 1980s and 1990s, legislation was finally passed all over the world banning the use of chlorofluorocarbons (CFCs) in commercial and industrial products such as spray cans and refrigerators. This gas (and many other like it) float up to the stratosphere where they bond with the ozone layer, peeling off one oxygen molecule and turning it back into pure oxygen. Because of this, the ozone layer has been depleted. Depletion of the ozone layer results in increased UV radiation reaching the Earth’s surface, which in turn leads to a greater chance of overexposure to UV radiation and the related health effects of skin cancer, cataracts, and immune suppression.
If you want to avoid ending up in skin cancer pictures sometime in the future, then make sure you are getting adequate protection when you are out in the sun. Avoid getting sunburned or tanned as much as possible!
If you have questions about skin cancer contact your local doctor, who will arrange for you to see a dermatologist.
