A lipoma refers to a benign, slow-growing tumor composed of fat cells that form within the soft tissues of the body. The word "lipoma" is derived from the Greek terms "lípos" (meaning fat) and "oma" (meaning tumor). These growths typically develop just beneath the skin, but they may also occur deep within the muscles, tendons, or internal organs.
Lipomas are generally small, smooth, and round in shape, with a soft, rubbery texture. They are commonly found in middle-aged adults, though they may occur at any age. These tumors are usually painless and noncancerous, often discovered by physical examination or if they become noticeable due to their size or location.
The exact cause of lipoma formation remains unknown, although genetic and hereditary factors may contribute to their development. In some cases, lipomas may be associated with certain medical conditions such as Madelung's disease or familial multiple lipomatosis.
Most lipomas are harmless and do not require medical treatment. However, if a lipoma causes discomfort or affects a person's appearance or functionality, surgical removal may be considered. Nevertheless, lipomas do not have the propensity to become cancerous or metastasize, hence, treatment is typically done for cosmetic reasons or to relieve symptoms.
In summary, a lipoma is a noncancerous tumor composed of fatty tissue that typically develops beneath the skin and grows slowly over time. While they are generally harmless, medical intervention may be necessary depending on their size, location, or associated symptoms.
