A lipoma is a slow-growing deposit of fat beneath the skin. It is soft, moveable, and almost always harmless. What causes one to form is not fully understood, but genetics, age, injury, and certain medical conditions all play a role. This blog covers what lipomas are, what causes them, who is most likely to develop them, and when removal is the right decision.
A lipoma is not a tumour in the way most people understand the word. It is a benign overgrowth of fat cells encased in a thin fibrous capsule, sitting just beneath the skin. It moves freely when pressed, feels soft and rubbery, and almost never causes pain. Most people discover one by accident.What triggers the fat cells to multiply and cluster is not always identifiable. Several factors are consistently associated with lipoma development, but no single cause applies to every patient.
According to Dr Harikiran Chekuri, one of India’s pioneering plastic surgeons, “Most lipomas are benign and cause no medical harm. The decision to remove one comes down to size, location, discomfort, and the patient’s own preference. What matters clinically is that any soft tissue lump gets properly assessed before it is dismissed as a lipoma because not every lump is one.”
What Actually Causes a Lipoma to Form?
No single cause explains all lipomas. The current evidence points to a combination of factors.
Genetics: The strongest predictor. Lipomas run in families. A condition called familial multiple lipomatosis causes clusters of lipomas across the body and is directly inherited. A patient with a parent or sibling who developed lipomas is significantly more likely to develop them as well.
Age: Most lipomas appear between the ages of 40 and 60. They are rare in children outside of inherited conditions. Fat cell behaviour changes with age, and lipoma formation becomes more common as that change accumulates.
Trauma or injury: A theory called the adipocyte trauma hypothesis suggests that a physical impact to an area can trigger local fat cells to proliferate abnormally. Some patients report a lipoma appearing at a site of prior injury, though the link is not universally confirmed.
Medical conditions associated with lipomas: Certain conditions carry a known association. Madelung disease causes large lipomas around the neck and shoulders. Gardner syndrome, Cowden syndrome, and adiposis dolorosa all present with multiple lipomas as part of a broader clinical picture. In these patients, the lipomas are a symptom rather than a standalone finding.
Sedentary lifestyle and metabolic factors: Some evidence suggests a link between low physical activity, high BMI, and lipoma formation, though lipomas also develop in lean, active individuals. This is not a cause in the direct sense it is a risk factor that may contribute.
What lipomas are not caused by: Diet alone, stress, or cancer. A lipoma is not a precancerous lesion. The rare malignant equivalent a liposarcoma looks and behaves differently and is assessed through imaging and biopsy, not appearance alone. Any lump that grows rapidly, feels hard, or causes pain should be assessed clinically before being assumed to be a lipoma. Lipoma removal at Redefine includes histological confirmation of every specimen after excision.

When Does a Lipoma Need to Be Removed?
Most lipomas do not require treatment. Removal is a decision, not a requirement unless the lipoma is causing specific problems.
When removal is recommended: A lipoma warrants removal when it is growing, pressing on a nerve causing pain or numbness, restricting movement, or causing cosmetic concern. It also requires excision when clinical examination alone cannot confirm it is benign and histological assessment is needed.
When removal can wait: A small, stable lipoma that causes no symptoms and has been confirmed as benign on clinical examination. These can be monitored without intervention. Regular check-ups to confirm the lump is not changing in size, texture, or character are sufficient.
How lipomas are removed: The standard approach is surgical excision under local anaesthesia through a small incision. The lipoma is removed intact with its capsule, which significantly reduces the chance of recurrence. Liposuction is an option for larger lipomas where minimal scarring is prioritised, though complete capsule removal is less certain with this technique. For patients with multiple lipomas, procedures can be staged or combined in a single session depending on size and location.
What to tell your surgeon: How long the lump has been present, whether it has grown recently, whether it causes pain or numbness, and whether there is a family history of similar lumps. That information shapes the assessment before examination begins.

A lipoma is almost always benign. That does not mean every soft tissue lump is. Get it assessed, get it confirmed, and then decide.

Frequently Asked Questions
Are lipomas dangerous?
In almost all cases, no. Lipomas are benign fatty lumps with no malignant potential. Any lump that grows rapidly, feels hard, or causes pain should be clinically assessed before being assumed to be a lipoma.
Can a lipoma turn into cancer?
Lipomas do not become cancerous. A liposarcoma a malignant fatty tumour is a different condition entirely. It is assessed through imaging and biopsy, not visual appearance.
What causes lipomas to form?
Genetics is the strongest factor. Age, prior trauma to the area, and certain medical conditions such as familial multiple lipomatosis are also associated. There is no single confirmed cause for all lipomas.
Do lipomas need to be removed?
Only if they are growing, causing pain or numbness, restricting movement, or the patient wants them removed for cosmetic reasons. Stable, asymptomatic lipomas can be monitored without treatment.
Will a lipoma come back after removal?
Not if it is removed completely with its capsule intact. Incomplete removal where the capsule is left behind is the most common reason for recurrence.
