You're Concerned About a Spot on Your Skin: While a consultation with a dermatologist is recommended for any suspicious mole or growth, this is especially true if you notice any warning signs of melanoma, such as:
Changes in an existing mole: Asymmetry, irregular borders, colour variation (black, brown, red, white, or blue), or a diameter larger than 6 millimetres (about the size of a pencil eraser).
A new mole that looks unusual: This could be a mole with any of the characteristics mentioned above, or one that appears different from your other moles.
A sore that doesn't heal: Melanoma can sometimes appear as a persistent wound that bleeds easily.
Redness or swelling around a mole: Inflammation or tenderness around a mole can be a cause for concern.
Itching: While itching isn't a specific indicator of melanoma, any unusual changes in sensation around a mole warrant a check-up.
