What Causes Lipomas?

The exact cause of lipomas is unknown at this time. However, if you have lipomas, it is likely that the condition may also run in your family as there is often is a genetic predisposition to this condition.
Lipomas are typically small at around two inches or less in diameter, but rarely they can grow to be much larger. Lipomas are typically found just under the skin in the neck, shoulders, back, arms, thighs, or abdomen, but can be located virtually anywhere on the body. A lipoma is usually soft to the touch and may feel “doughy,” but you may also feel some pain or tenderness with palpation, especially if the lipoma grows.
Who Gets Lipomas?
It is possible for nearly any person at any age to develop a lipoma. Below are a few risk factors:
- Family history of lipomas
- Between the ages of 40-60
- Recent injury
- Obesity
- Certain genetic or medical disorders
How Can I Prevent Lipomas?
Because obesity puts you at a higher risk for developing a lipoma, you can, in some cases, prevent them by following a healthy diet and exercising regularly in order to maintain a healthy and stable weight. However, lipomas due to other causes are not generally preventable.
Why Treat Lipomas?
It is advisable to see a dermatologist and evaluate a potential lipoma to ensure it is not a more serious issue. Once a diagnosis has been made, not all lipomas will require treatment. However, a lipoma can be painful, continue to grow without treatment, or bother you for another reason. In some cases, a lipoma may press on a nerve, which can cause pain or discomfort. The lipoma may also be cosmetically unappealing or affect your muscle movement. In these cases, you should seek treatment from a board-certified dermatologist.
How Can I Treat Lipomas?
Lipomas are typically removed by a dermatologist through surgical excision with a small incision.

Lipoma FAQs
What causes lipomas?The exact cause of lipomas is unknown at this time. However, if you have lipomas, it is likely that the condition may also run in your family as there is often a genetic predisposition to this condition. Other factors that can contribute to their formation include recent injury or trauma, age (adults ages 40-60 years old), obesity, and certain genetic or medical disorders. What are the symptoms of a lipoma?Lipomas are usually painless, soft and “doughy” to the touch, and can move slightly with a bit of pressure. However, they can become tender or painful depending on where on your body they develop, especially if they grow and press on a nerve. Are lipomas cancerous?No, lipomas are not cancerous. They are benign (non-cancerous) tumors/overgrowths of fat cells. Who is at risk of developing lipomas?It is possible for nearly any person at any age to develop a lipoma. Some risk factors include genetic predisposition/family history of lipomas, between the ages of 40-60, recent injury, obesity, and certain genetic or medical disorders. How are lipomas diagnosed?Our board-certified dermatologists at Arlington Dermatology can diagnose lipomas through a physical examination of the lesion’s texture, movement, and size. If there is any uncertainty, additional diagnostic tests such as an ultrasound, MRI or CT scan, and biopsy can be used to confirm the diagnosis. Do lipomas require treatment?Although lipomas are benign (non-cancerous) and typically asymptomatic, it is advisable to see a board-certified dermatologist to evaluate a potential lipoma to confirm the diagnosis and ensure it is not a more serious issue. Once a diagnosis is made, not all lipomas require treatment. However, in some cases, lipomas can become painful or uncomfortable, continue to grow, affect muscle movement due to their location, or be cosmetically unappealing. In these cases, a board-certified dermatologist at Arlington Dermatology can diagnose and surgically remove a lipoma if desired. Can lipomas come back after removal?Yes, lipomas can come back after removal; however, it is uncommon. If a lipoma is completely excised, including its capsule, it usually does not grow back. However, in some cases, a lipoma may recur in the same area or nearby. Reasons for recurrence include an incomplete removal, a genetic predisposition to developing lipomas, or medical conditions that are associated with developing multiple lipomas. How are lipomas treated?Lipomas are typically surgically removed through a surgical excision with a small incision. Are there any non-surgical treatments for lipomas?The most common treatment option for lipomas is surgical removal. However, there are some non-surgical treatment options, such as liposuction, although their success varies. The only treatment that can entirely remove a lipoma, including the lipoma capsule, is surgical excision. Where can lipomas develop?Lipomas can develop virtually anywhere on the body; however, they are commonly found just under the skin in the neck, shoulders, back, arms, thighs, or abdomen. |
