Lipoma – Symptoms and Causes
Overview
Lipomas are benign, slow-growing fatty lumps that develop between the skin and muscle layer. These soft, doughy masses are moveable under the skin and typically painless, although they may cause discomfort if they press on nearby nerves or tissues.
Their characteristic fatty texture and mobility make them relatively easy for medical professionals to identify during physical examinations.
Lipomas can develop almost anywhere in the body, but the most common areas include the:
- Shoulders
- Neck
- Chest
- Arms
- Back
- Thighs
They can range in size from pea-sized to several centimeters in diameter, and in rare cases, can grow to be quite large.
Causes and Risk Factors
The exact cause of lipomas remains unknown, but they are believed to result from an overgrowth of fat cells. Possible contributing factors include:
- Genetics โ Lipomas can run in families.
- Body trauma โ Injury to a specific area may trigger lipoma formation.
Lipomas are most commonly discovered during middle age, particularly in individuals between the ages of 40 and 60. Some people may develop multiple lipomas throughout their bodies.
Treatment and When to See a Doctor
Most lipomas are non-cancerous and harmless, and typically do not require treatment. However, removal may be recommended if the lipoma:
- Causes discomfort or pain
- Grows in size
- Creates cosmetic concerns
- Interferes with daily activities
If a lipoma is painful, growing rapidly, or causing other symptoms, it’s advisable to consult a healthcare provider to determine if removal is necessary.
