Understanding Malignant Melanoma: The Skin Cancer Cell Type Arising from Pre-existing Nevi

What skin cancer cell type frequently arises from pre-existing nevi?

The skin cancer cell type that frequently arises from pre-existing nevi is known as malignant melanoma

The skin cancer cell type that frequently arises from pre-existing nevi is known as malignant melanoma. Nevi, also known as moles, are common benign skin growths that usually appear during childhood or adolescence. While most moles are harmless and do not develop into cancer, some can undergo changes over time and become cancerous.

Malignant melanoma primarily originates from the pigment-producing cells called melanocytes. Melanocytes are responsible for producing the pigment melanin, which gives color to the skin, hair, and eyes.

When a pre-existing nevus transforms into melanoma, it is called a dysplastic nevus or an atypical mole. These moles typically possess abnormal features, such as irregular borders, asymmetry, differing colors, and larger size compared to normal moles. Dysplastic nevi have a higher chance of developing into malignant melanoma, although the majority of them will still not progress to cancer.

It is essential to monitor any changes in the size, shape, or color of existing moles, as well as the appearance of new moles. If you observe any suspicious changes or abnormal characteristics in your moles, it is crucial to seek medical attention for a proper diagnosis and, if required, prompt treatment. Regular skin self-examinations and yearly dermatology check-ups are recommended to detect any potential skin cancer early and ensure appropriate management.
