Lipoma, sebaceous cysts, and pigmented moles are common skin lumps that many people notice at some point in life. A lipoma is a soft, slow-growing lump made of fatty tissue and is usually harmless and painless. Sebaceous cysts form when skin oil becomes trapped, creating a firm, round bump that may sometimes become infected. Pigmented moles are colored spots caused by clusters of pigment-producing cells and are often harmless, though changes in size, color, or shape should be checked. Understanding these skin lumps helps reduce fear and encourages timely medical advice when needed.
