B stands for border irregularity.
C stands for color. If the color is intensely black, possibly with a bluish tint, or the color is uneven across the mole, this is suspicious of a melanoma. If you scored average or above, talk to your dermatologist about having your skin monitored for signs of cancer. Melanoma is the most lethal form of cancer and can spread quietly and quickly without a sign. Author Catherine Poole in her book Melanoma Prevention Detection and Treatment offers us a comprehensive look at melanoma.
