Edited by Tayyaba Rehman — By Fiza Rafique — Published on June 13, 2024

Key Differences
Moles, or nevi, are clusters of pigmented cells that appear as small, dark brown spots on the skin, though their color can range from pink to black. Warts are caused by various strains of HPV and manifest as raised, rough-textured growths on the skin or mucous membranes.
Moles are usually present from birth or develop during childhood and early adulthood, often changing in appearance over time due to factors like sun exposure or hormonal changes. Warts can appear at any age and often develop on the hands, feet, and other parts of the body that come into frequent contact with HPV-contaminated surfaces.
While most moles are benign and pose no health risk, a sudden change in a mole's appearance can be a sign of melanoma, a serious form of skin cancer. Warts, though not associated with cancer, can be uncomfortable, unsightly, and spread to other parts of the body or to other people.
The treatment for moles typically involves monitoring for any changes in size, shape, or color, with surgical removal being an option for those that are suspicious or cosmetically undesirable. Warts can be treated with over-the-counter remedies, cryotherapy, salicylic acid, or other medical interventions to remove the growth.
Moles are generally uniform in color and have a smooth, round shape, ranging from flat to slightly raised from the skin surface. Warts are characterized by their rough surface, and some may have black pinpoints, which are small, clotted blood vessels.
