Malignant melanoma can have a variety of physical characteristics. Some melanomas are small, hard bumps on the surface of the skin, while others show up as flat, black marks underneath a fingernail.
Visual signs of melanoma
Because it can be difficult to determine whether a lump or mole is malignant melanoma – and because a diagnosis can only be made by a medical professional – it’s best to promptly discuss any unusual skin changes with a dermatologist or oncologist. These include:
- Moles that have recently changed in appearance (i.e., grown larger or become more raised above the surface of the skin)
- Moles that have blurred borders or are uneven in color
- Bumps, sores or rashes that bleed, flake or develop a scab but do not heal
- Small, scaly patches on the skin
- Raised nodules that are itchy, tender or painful to touch
- Dark stripes of pigment underneath a fingernail
Most moles, bumps and rashes are not a cause for concern. However, in the unlikely event that malignant melanoma is present, early detection can lead to a wider range of treatment options, a more favorable prognosis and a better quality of life.
