The killer pimple: Doctors warn of aggressive form of skin cancer which is six times more likely to kill if it is not removed within two months

• Nodular melanomas look like a red lump rather than an ugly dark mole
• The aggressive form of skin cancer makes up just 15 per cent of melanoma cases but causes 43 per cent of melanoma deaths
• The deadly melanomas grow at four times the rate of other melanomas
• The skin cancers can be harmless-looking so often go undiagnosed

Dermatologists have raised the alarm on an aggressive form of melanoma that looks like a harmless pimple but kills hundreds of Australians a year.

Diagnosis delays mean people with the cancer are six times more likely to die than from other melanomas.

Nodular melanomas usually appear on the skin as a red nodule rather than an ugly dark mole, leading doctors to mistake them for relatively harmless forms of skin cancer or even pimples.
