Best answer: Why does Australia have such high skin cancer rates?

Australia has one of the highest rates of skin cancer in the world. This is due largely to our climate, the fact that many of us have fair skin that isn’t really suited to such harsh conditions, our proximity to the equator (high UV levels) and our social attitudes and love for the outdoors.

Why is skin cancer most common in Australia?

Australia has one of the highest rates of skin cancer in the world. Anyone can be at risk of developing skin cancer, though the risk increases as you get older. The majority of skin cancers in Australia are caused by exposure to UV radiation in sunlight.

What is one reason why the rate of skin cancer in Australia is so high?

Skin cancers (including both melanomas and non-melanomas) result from skin damage by ultraviolet radiation (UVR), which accounts for at least 95% of all skin cancers in Australia. Australia experiences high levels of UVR, resulting from the reduction in their ozone layer since the 1970s.

Why have skin cancer rates increased?

The increase in the incidence of skin cancer can be mainly attributed to the use of artificial sunlamps and intense exposure to ultraviolet (UV) light (Bologniaetal.,2012).

How prevalent is skin cancer in Australia?

Skin cancer is the most common cancer diagnosed in Australia. About two in three Australians will be diagnosed with some form of skin cancer before the age of 70. Almost 980,000 new cases of BCC and SCC are treated each year. BCC can develop in young people, but it is more common in people over 40.

Why doesn’t Australia have an ozone layer?

The ozone layer is depleted in two ways. Firstly, the ozone layer in the mid-latitude (e.g. over Australia) is thinned, leading to more UV radiation reaching the earth. … Secondly, the ozone layer over the Antarctic, and to a lesser extent the Arctic, is dramatically thinned in spring, leading to an ‘ozone hole’.

Why does Australia have spiders?

Victoria state generally sees this natural phenomenon during the winter, when it receives most of its rain. When this happens, spiders, which can produce a wide variety of silks, produce this kind of web which is very thin and delicate, and allows them to fly away with the breeze, sometimes as far as 100 km.

Why light from the sun can cause skin cancer?

How can UV cause skin cancer? Too much UV radiation from the sun or sunbeds can damage the DNA in our skin cells. DNA tells our cells how to function. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.

Who is more prone to skin cancer?

Skin cancer is more common in fair skinned people because they have less of the protective pigment called melanin. People with darker skin are less likely to get skin cancer. But they can still get skin cancer. Darker skinned people are particularly at risk of skin cancer where the body has less direct sun exposure.

Are skin cancer rates increasing or decreasing?

Despite great advances in medical research and treatment, we find ourselves in the midst of an ongoing epidemic. Skin cancer incidence rates of the three major types of skin cancer – basal cell carcinoma, squamous cell carcinoma and melanoma – continue to rise.

What is the most common skin cancer in Australia?

Non-melanoma skin cancers, now called keratinoctye cancers, are the most common cancers in Australia, however most are not life-threatening. There are two main types: basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). BCC accounts for about 70% of non-melanoma skin cancers.

Who does melanoma affect most in Australia?
