The following symptoms are usually associated with the incidence of melanoma:
- A mole, sore, lump, or growth on the skin may be the primary indicator of malignant melanoma.
- Any change in appearance of a pigmented skin sore over time.
- Any bleeding from a skin growth.
The concept of ABCDs is widely advocated for easy identification of melanomas -
( A) Asymmetry: One half of the mole is different from the other half.
(B) Borders: Borders of the lesion or growth are irregular
( C) Colour: Colour changes from one area to another; the colour may be different from the rest of your moles.
(D) Diameter: The spot is usually (but not always) larger than 6 mm in diameter, i.e. the size of a pencil eraser.
This concept need not be always accurate, since potentially harmless moles may show these features. Malignant melanoma may not satisfy all of these features at times. However it is best not to take chances, consult a doctor whenever there is a suspicious skin lesion.
