15008 Lipomas

Overview

A lipoma is a harmless, slow-growing lump of fat that develops just under the skin. It feels soft and doughy and moves easily when you press on it.

Yes, lipomas are very common. Many people will develop at least one in their lifetime.

Anyone can get a lipoma, but they are most often found in adults between 30 and 60 years old. Some people have a family history of lipomas.

Symptoms

Common symptoms

• A soft, round, or oval lump under the skin
• The lump moves easily when you press on it
• Usually painless, though it may feel slightly tender in some cases
• Grows slowly over months or years
• Often found on the neck, shoulders, back, arms, or thighs

Symptoms in children

• Lipomas in children are rare, but they can occur.
• They feel the same as adult lipomas — soft, movable, and usually painless.
• Any new lump in a child should be checked by a doctor to rule out other causes.

Symptoms in older adults

• Lipomas may become more noticeable as the skin thins with age.
• They are still usually harmless, but age-related changes can make them feel firmer.
• Multiple lipomas can sometimes appear, especially in adults over 60.

Causes

Main causes

• The exact cause is unknown, but lipomas form from overgrowth of fat cells.
• Genetics are thought to play a role — lipomas often run in families.
• In rare cases, a previous injury to a body area may trigger the growth.

Risk factors

• Family history of lipomas
• Being between 30 and 60 years old
• Certain rare inherited conditions, such as familial multiple lipomatosis
• Having a personal history of lipomas

When to see a doctor

See a doctor urgently if:

• See a doctor the same day if a lipoma becomes painful, red, or tender.
• Seek urgent advice if a lump grows rapidly, feels hard, or is attached to deeper tissue.
• If you notice multiple new lumps or any signs of infection, contact a healthcare provider promptly.

Book a routine appointment if:

• Any new lump under the skin should be checked once to confirm it is a lipoma.
• If you have existing lipomas, you can mention them at your regular check-up.
• If a lipoma is affecting your comfort or confidence, ask your doctor about options.

Diagnosis

Doctors usually diagnose a lipoma by feeling it during a physical examination. Lipomas have a distinctive soft, doughy texture and slide easily under the skin.

Tests that may be done

• In most cases, no tests are needed.
• If the doctor is unsure, an ultrasound or MRI can create a detailed image of the lump.
• Rarely, a small tissue sample (biopsy) may be taken to confirm the diagnosis.

What to expect at your appointment

Your doctor will ask about your symptoms and medical history, then feel the lump to check its size, texture, and movement. They will tell you whether it looks like a lipoma and whether any follow-up is needed.

Treatment

Most lipomas are harmless and do not require any treatment. If a lipoma is uncomfortable, growing, or bothersome for other reasons, there are several safe options your doctor can discuss with you.

Self-care at home

• Leave the lipoma alone — do not squeeze, pick, or try to drain it.
• Keep the overlying skin clean and protect it from injury.
• Monitor the lump for any changes in size, shape, or sensation.
• Take a photo with a ruler underneath to track its size over time.

Medical treatments

If treatment is needed, a doctor may offer surgical removal (cutting out the lipoma) or liposuction (using a thin tube to remove the fat). In some cases, steroid injections may shrink the lipoma, though results are not always permanent. The right approach depends on the size, location, and your preferences. Your healthcare provider will explain the benefits and risks before you decide.

When is surgery considered?

Surgery may be considered if the lipoma is large, painful, growing quickly, or pressing on a nerve or joint. This is usually a minor procedure done with local anaesthetic (numbing the area), and you often can go home the same day.

Living with this condition

Having a lipoma rarely affects daily life. Most people simply ignore it. If a lipoma is somewhere it gets rubbed or irritated, you can adjust clothing or padding to reduce discomfort.

Lifestyle tips

• Stay physically active to maintain a healthy weight and general well-being.
• Keep an eye on the lipoma and note any changes.
• If you have multiple lipomas, consider taking regular photos to track them.
• Avoid smoking and excessive alcohol, which are not directly linked to lipomas but harm overall health.

Diet and exercise

There is no special diet that removes lipomas. A balanced diet rich in fruits, vegetables, whole grains, and lean protein supports your body's general health. Regular exercise helps keep your circulation and tissues healthy, but it will not dissolve a lipoma.

Mental health and emotional wellbeing

Anyone can feel anxious or worried when they find a new lump. This is normal. Once a doctor confirms it is a lipoma, try to reassure yourself that it is harmless. If worry persists, talk with your doctor or a counselor.

Prevention

There is no known way to prevent lipomas, because their exact cause is not understood. Staying healthy and being aware of changes in your body are the best precautions.

Screening programmes

There is no routine screening test for lipomas. However, it is wise to check your skin regularly for any new or changing lumps and to mention them to your doctor.

Complications

If left untreated

• Most lipomas cause no complications at all.
• In rare cases, a large lipoma can press on nearby nerves or blood vessels, causing pain or restricted movement.
• Untreated lipomas may continue to grow slowly over many years, but they do not spread to other parts of the body.

Long-term outlook

The outlook is excellent. Lipomas are non-cancerous, slow-growing, and generally harmless. If you choose to have one removed, the procedure is straightforward and recurrence is uncommon. You can live a full, healthy life with lipomas.
