Are you concerned about a soft, rubbery lump under your skin? You may be dealing with a lipoma, a common benign tumor composed of fat cells. In this comprehensive guide, we’ll explore everything you need to know about lipomas, including their causes, symptoms, treatment options, and more.

What are Lipomas?

Lipomas are non-cancerous growths that develop within the fatty tissue under the skin. They typically feel soft and movable, and they may vary in size from small pea-sized nodules to larger lumps. While lipomas can occur anywhere on the body, they most commonly develop on the shoulders, neck, back, arms, and thighs.

Causes of Lipomas:

The exact cause of lipomas is not fully understood. However, several factors may contribute to their development, including:

  • Genetic predisposition: Lipomas may run in families, suggesting a genetic component to their formation.
  • Trauma: Injury or trauma to the fatty tissue may trigger the growth of a lipoma.
  • Hormonal factors: Hormonal imbalances or changes may play a role in the development of lipomas.

Symptoms of Lipomas:

Lipomas are typically asymptomatic and may not cause any noticeable symptoms. However, some individuals may experience:

  • A soft, rubbery lump under the skin.
  • A lump that is painless and moves easily when touched.
  • Discomfort or pain if the lipoma presses on nearby nerves or organs.


Diagnosing a lipoma usually involves:

  • Physical examination: Your healthcare provider will examine the lump and assess its size, shape, and texture.
  • Imaging tests: In some cases, imaging tests such as ultrasound or MRI may be performed to confirm the diagnosis and evaluate the size and location of the lipoma.

Treatment Options:

Treatment for lipomas may not be necessary if they are small, asymptomatic, and not causing any cosmetic concerns. However, if treatment is desired or if the lipoma is causing symptoms, options may include:
  • Surgical removal: Excision of the lipoma is typically performed under local anesthesia as an outpatient procedure. The surgeon makes an incision over the lipoma, removes the growth, and closes the incision with sutures.
  • Liposuction: For larger or multiple lipomas, liposuction may be used to remove the fatty tissue through a small incision.
  • Steroid injections: In some cases, steroid injections may be administered directly into the lipoma to reduce its size and symptoms.

Recovery Time:

Recovery following surgical removal of a lipoma is usually quick, with most patients able to resume normal activities within a few days. Sutures may be removed within 1 to 2 weeks, and any discomfort can be managed with over-the-counter pain medications.

Risk Factors:

While lipomas are generally harmless, potential risks associated with surgical removal may include:

  • Infection at the incision site.
  • Bleeding or hematoma formation.
  • Scarring.
  • Recurrence of the lipoma in the same location.


Since the exact cause of lipomas is not known, there are no specific prevention strategies. However, maintaining a healthy lifestyle and avoiding trauma to the fatty tissue may help reduce the risk of developing lipomas.
