Melanoma typically starts as a growth or lesion that differs from the surrounding skin. Often, these growths are not cancerous at first, but can develop into cancer over time. This is why regular skin checks are so important. Melanoma can be cured if it is discovered and treated early.
There are four key warning signs of melanoma:
- A mole or dark area with an irregular shape, or two different looking halves
- A mole or dark area with borders that are blurred, rough or notched
- A mole with uneven color
- A mole that is larger than ¼ inch (the size of a pencil eraser)
Additional symptoms may include:
- Sores that do not heal
- Pigment, redness or swelling that spreads to the surrounding skin
- Itchiness, tenderness or pain
- Moles that change in texture, ooze or bleed
Not all melanomas develop from moles and symptoms can vary, so it is very important to discuss changes in your skin with your doctor.
While many melanomas develop in areas exposed to the sun, this is not always the case. In addition to examining your legs, torso, arms, face and neck, it is important to look at the areas between your toes, underneath nails, palms of the hands and soles of the feet, genitals and even the eyes.
