Final answer:
Nevus is the medical term for a mole, a benign skin growth composed of melanocytes. Moles require monitoring as they have the potential to develop into melanoma, the deadliest form of skin cancer, which exhibits asymmetrical shape, irregular borders, color changes, and large diameter—characteristics summarized by the mnemonic ABCDs of skin cancer.
Step-by-step explanation:
Nevus is also known as a mole. Moles are common skin growths resulting from benign accumulations of melanocytes, which are the pigment-producing cells in the epidermis of the skin. While moles themselves are usually harmless and noncancerous, they need to be monitored as they can sometimes develop into melanoma, a serious and potentially fatal form of skin cancer characterized by the uncontrolled growth of melanocytes. Melanomas typically present as large brown or black patches with uneven borders and a raised surface. Early detection of skin cancer through regular skin examinations is crucial as it has the highest chance of successful treatment when caught early.
In contrast, macules are flat spots on the skin, papules are small raised bumps, and psoriasis is a chronic skin condition characterized by red, scaly patches. None of these terms are synonymous with moles. When examining the skin, particularly moles, the ABCDs of skin cancer can be a useful guide: Asymmetrical shape, irregular Borders, Color variation, and Diameter greater than 6mm.
ABCDs of skin cancer is a mnemonic to help people remember the warning signs when examining moles and spots on the skin for potential skin cancer. Unlike normal moles, skin cancers like melanoma are generally asymmetrical, have irregular borders, may be very dark in color, and may have a relatively great diameter.
