Skin cancer and the sun
Outdoor workers and workers who are outdoors periodically will be exposed to the sun and the two main hazards this presents; over exposure to UV radiation and heat stress.
Queensland experiences tropical and sub-tropical weather and has a large proportion of sunny days. Exposure to ultraviolet (UV) radiation is cumulative and can cause sunburn in the short term and over long periods of time can lead to eye damage an increased incidence of skin cancers (including melanoma). Queensland has the highest rate of skin cancer in the world. If you live in Queensland, you are at risk of developing skin cancer.
Skin cancer is a serious disease that can cause disfigurement and death. It is the most common cancer in Australia. Skin cancer is caused by an accumulation of overexposure to ultra violet radiation (UVR) from the sun or artificial sources penetrating the skin and damaging living cells. The UV index measures the daily levels of UV radiation. When the UV index is three or above it can damage your skin or lead to skin cancer.
Examples of skin cancers
There are three main types of skin cancer named after the type of cell in the skin from which they originate.
Basal Cell Carcinoma (BCC) is the most common but least dangerous. A BCC appears as a lump or scaly area. It may be red, pale or pearly in colour or a sore that won't heal.
Squamous Cell Carcinoma (SCC) are less common than BCCs and not as dangerous as melanoma but may spread to other parts of the body if left untreated.
Melanoma is the most dangerous type of skin cancer. A melanoma appears as a new spot, or an existing spot, freckle or mole that changes and can be anywhere on the body. If left untreated, the cancer cells can spread to other parts of the body. About 1200 Australians die every year from melanoma.
Sunspots are not a form of skin cancer, but are a warning sign as they occur on skin which has had enough sun exposure to develop skin cancer. Sunspots are small, scaly patches of skin that generally occur on the arms, face, nose and ears.
It is possible to see sunlight and feel infrared radiation (heat), but not see or feel ultra violet (UV) radiation. When the daily UV index is three or above it can damage skin or lead to skin cancer. As UV radiation can vary greatly between places and day to day, a range of precautions must be available to address the risks presented by the specific workplace and its work practices and you need to be aware of the UV levels in your region.
The Bureau of Meteorology (BOM) issues a national UV index forecast every day, which uses the World Health Organisation's global solar UV index. The BOM's Queensland UV forecast gives daily information on the current UV risk.
Nearly all skin cancers can be cured if detected and treated early. Skin cancers rarely hurt and are much more frequently seen than felt. It is important that you or a medical practitioner regularly checks your skin for changes in shape, colour or size of an existing freckle or mole or a new spot. Cancer Council Queensland has information on how to perform skin self examination.
Contact a medical practitioner if you are concerned about skin changes.
