Why is Australia skin cancer rate so high?

As the ozone layer depletes, the atmosphere loses its protective filter and more of the dangerous UV radiation reaches the surface of our planet. This depletion is directly related to the growing number of skin cancer cases.

Why does Australia have higher skin cancer rates?

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.

Why does Australia get more UV light than other parts of the world?

Ozone in the atmosphere can absorb ultraviolet light, which stops the light from reaching Earth’s surface, so people absorb less of it. Australia has less ozone than other places, like Brazil, and this is why Australia gets more ultraviolet light.

Over the same period, the age-standardised incidence rate increased from 27 cases per 100,000 persons (28 for males and 26 for females) in 1982 to 54 cases per 100,000 in 2017.

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.

Why is Australian sun so strong?

Australia’s unusually harsh sunshine results mainly from its location in the Southern Hemisphere. The elliptical orbit of the Earth places the Southern Hemisphere closer to the sun during its summer months than the Northern Hemisphere during its summer.

Why is there no ozone layer over Australia?

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’.

  • Australia receives much more solar radiation than California or even the Mediterranean famed for its sunny summers and beautiful beaches.

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).

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 does melanoma affect most in Australia?

Why Does Queensland have the highest rate of skin cancer?

Why are Queensland’s skin cancer rates so high? The state’s tropical climate increases the risk of sunburn. Ultraviolet radiation (UVR) is the main cause of skin cancer and in Queensland, UVR levels are high enough every day – even on overcast days – to burn our skin and damage skin cells.
