Melanomas and nevi are two terms used in dermatology to describe different types of skin lesions.
Melanoma is a type of skin cancer that begins in the melanocytes, which are the cells that produce the pigment melanin. Melanomas usually appear as dark, asymmetrical spots or moles on the skin. They can develop on any part of the body, including areas not regularly exposed to the sun. Melanomas have the potential to spread to other parts of the body and become life-threatening if not detected and treated early. Risk factors for developing melanoma include sun exposure, family history of the disease, fair skin, and a large number of moles or atypical moles.
Nevi, commonly known as moles, are benign growths that form on the skin due to an accumulation of pigment-producing cells called melanocytes. Moles can be present at birth or develop later in life. They come in various shapes, sizes, and colors, and can appear anywhere on the body. Most moles are harmless and do not require treatment unless they change in size, shape, or color, or begin to cause discomfort. However, some moles, especially those that are large or atypical in appearance, may be considered as precursors for melanoma and require further examination or removal.
Both melanomas and nevi can be diagnosed through physical examination and, when necessary, a biopsy. It is important to regularly check your skin for any changes in moles or the appearance of new lesions, as early detection is crucial for the successful treatment of melanoma. Seeking prompt medical attention for any suspicious skin lesion is highly advised.
