Get support Skin Check Toolkit THE 'ABCDE' RULE The ABCDE Rule of skin cancer is an easy-to-remember system for determining whether a mole or growth may be cancerous. When a doctor performs a skin check, they look at every lump, spot and mole on your entire body; areas of concern are assessed for signs of skin cancer using the ABCDE method of melanoma detection. As kids we are taught to 'slip, slop, slap, seek and slide' but not that much about the ABCs of skin cancer - a simple process that allows anyone to check their skin for the warning signs of skin cancer. Pop over to the shop and pick up one of our Skin Check Cards, They simplify the ABCDE Rule of melanoma detection and may help you identify skin cancer early. If you see two or more warning signs, consult a doctor without delay. It may be nothing, but it's always better to be safe than sorry. Skin cancer, both melanoma and non-melanoma, can usually be treated successfully if caught early.
