Fatty tissue growth, often manifesting as lipomas, is typically caused by an overgrowth of fat cells. While the exact cause is often unknown, several factors contribute:
Genetic Predisposition
Some individuals are genetically predisposed to developing lipomas. This means a family history of lipomas increases the likelihood of developing them. [Reference: Lipomas are benign (not cancerous), fatty lumps that are quite common. Lipomas can appear anywhere where you have fat cells and most commonly grow on the neck, chest, back, shoulders, arms and thighs. The cause of lipomas is often unknown, but some families have a genetic tendency to develop them.]
Dercum's Disease
A rare disorder, Dercum's disease, is characterized by the growth of many painful lipomas, typically on the upper arms, legs, and other body parts. [Reference: Lipoma Causes ยท Dercum's disease: This rare disorder causes many painful lipomas to grow on different body parts such as your upper arms, legs,...]
Adiposis Dolorosa
Adiposis dolorosa is another condition marked by painful folds of fatty tissue or the growth of multiple benign fatty tumors (lipomas). [Reference: Adiposis dolorosa is a condition characterized by painful folds of fatty (adipose) tissue or the growth of multiple noncancerous (benign) fatty tumors called...]
Lipoma Formation: A Closer Look
Lipomas are benign tumors composed of adipose (fat) cells, often encapsulated by fibrous tissue. They develop in the fatty layer under the skin. [Reference: Lipomas are defined as a common subcutaneous tumor composed of adipose (fat) cells, often encapsulated by a thin layer of fibrous tissue.] Their growth is generally slow and they are usually not cancerous. [Reference: A lipoma is a slow-growing, fatty lump that's most often situated between your skin and the underlying muscle layer. A lipoma, which feels doughy and...] [Reference: A lipoma is a non cancerous (benign) lump that forms due to an overgrowth of fat cells. They most commonly develop in the fatty layer of the skin.]
Common Locations
Lipomas frequently appear on the arms, legs, back, shoulders, trunk, neck, and armpits. [Reference: Lipomas can appear anywhere where you have fat cells and most commonly grow on the neck, chest, back, shoulders, arms and thighs.] [Reference: Lipomas typically appear on the shoulders, trunk, neck, or armpits.]
Important Note: Not All Fatty Tissue Growth is a Lipoma
While lipomas are a common type of fatty tissue growth, other conditions can also cause lumps or changes in fat distribution. It's crucial to consult a healthcare professional for diagnosis and treatment.
