Tri-Cities Skin & Cancer Market Share Analysis for June 2026

Moles (nevi) are growths on the skin that are usually brown or black. They can appear anywhere on the body, alone or in groups. Moles occur when the cells in the skin grow in clusters instead of spreading evenly throughout the skin. These cells are what give skin its pigment, so moles appear darker than the skin. Many moles will darken over time, especially when exposed to the sun and during pregnancy. It is also common for hairs to grow on the mole. Individuals with lighter skin tend to have more moles than those with darker skin. Most people with moles have between 10 and 40. Moles are generally harmless. However, it is important to know that melanoma (the most serious form of skin cancer) can develop in or around a mole, so knowing your moles is essential to catching signs of cancer early.
