Melanoma
Fact sheet on melanoma
Melanoma arises from cells in the skin (melanocytes) which produce a brown pigment (melanin), the substance which gives skin its colour.
Melanoma:
- is the least common form of skin cancer but is the most deadly
- if untreated, melanoma cells spread quickly to other parts of the body and form secondary cancers
- appears as a new spot, or an existing spot, freckle or mole that changes colour, size or shape
- usually has an irregular or smudgy outline and is more than one colour (brown, black, red, white and/or light grey)
- grows over weeks to months, anywhere on the body (not just in places that get a lot of sun)
In 2005, melanoma was the tenth most common cause of cancer death in Australia2, with 1,273 deaths from melanoma in Australia in 20053.
Australian five-year relative survival rates after a diagnosis of melanoma are consistently high for all age groups and are the highest in the world. Melanoma has the second-highest five-year survival rate when compared with other cancers for both males and females4.
Early detection is important for successful treatment of melanoma. People, particularly anyone aged 50 years or over, should check their own skin regularly and seek medical advice immediately if they notice any changes. Those at high risk of melanoma may need a regular check from their GP or specialist dermatologist.
For further information on types of skin cancer and on how to check for skin changes, see the Australasian College of Dermatologists website.
