Malignant melanoma has also been linked to past sunburns and sun exposure at younger ages. A. Melanoma generally begins as a mottled, light brown to black flat blemish with irregular borders. Blemishes are usually at least a quarter of an inch in size and may turn shades of red, blue and white, crust on the surface and bleed. They frequently appear on the upper back, torso, lower legs, head and neck. When detected early, surgical removal of thin melanoma can cure the disease in most cases.
Early detection is essential.
Dermatologists recommend a regular self-examination of the skin to detect changes in its appearance, especially changes in existing moles or blemishes. Additionally, patients with risk factors should have a complete skin examination annually. Anyone with a changing mole should be examined immediately. Apply a sunscreen with a sun protection factor of at least 15, apply 15 to 30 minutes before going outdoors and reapply every two hours, especially when playing, gardening, swimming or doing any other outdoor activities. Wear protective clothing, including a hat with a wide brim and long-sleeved shirts and pants during prolonged periods of sun exposure.
