Skin cancer symptoms
Skin cancer symptoms include the appearance of new moles or changes to a mole, such as itching or bleeding.
Skin changes due to cancer often affect the back, legs, arms and face.
Warning signs of skin cancer include:
- Any change in size, colour, shape or texture of a mole or other skin growth
- An open or inflamed skin wound that won't heal
Melanoma, the most dangerous type of skin cancer, may appear as:
- A change in an existing mole
- A small, dark multicoloured spot with irregular borders - either raised or flat - that may bleed and form a scab
- A cluster of shiny, firm dark bumps
- Having a diameter larger than than 6mm (the size of a pencil rubber)
An easy way to remember the signs of melanoma is the ABCDEs of melanoma:
- Irregular Borders
- Two or more Colours or changes in colour
- Diameter larger than 6mm (the size of a pencil rubber)
- Elevated or Enlarged
Basal cell carcinoma may appear on sun-exposed skin as:
- A pearly or flesh-coloured oval bump with a rolled border, which may develop into a bleeding ulcer.
- A smooth red spot indented in the centre.
- A reddish, brown or bluish black patch of skin on the chest or back.
Squamous cell carcinoma may appear on sun-exposed skin as:
- A firm, reddish wart-like bump that grows gradually.
- A flat spot that becomes a bleeding sore that won't heal.
Seek medical advice if:
- An existing mole changes size, shape, colour or texture; or you develop a very noticeable new mole as an adult.
- A new skin growth or open sore does not heal or disappear in a few weeks.
