Other Skin Growths You Should Know About
Two other common types of skin growths are moles and keratoses.
Moles are clusters of heavily pigmented skin cells, either flat or raised above the skin surface. While most pose no danger, some-particularly large moles present at birth, or those with mottled colors and poorly defined borders-may develop into malignant melanoma. Moles are frequently removed for cosmetic reasons, or because they’re constantly irritated by clothing or jewelry (which can sometimes cause pre-cancerous changes).
Malignant melanoma is often asymmetrical, with blurred or ragged edges and mottled colors.
Solar or actinic keratoses are rough, red or brown, scaly patches on the skin. They are usually found on areas exposed to the sun, and sometimes develop into squamous cell cancer.
