You’re getting dressed one morning and you notice it — a small, soft, rubbery lump just under the surface of your skin. It moves around when you press it. It doesn’t really hurt. But it’s definitely something, and it wasn’t there before.
For millions of Australians, that lump turns out to be a lipoma — one of the most common and, reassuringly, most harmless soft tissue growths that exist. But “harmless” doesn’t always mean “leave it alone,” and knowing when to act makes a real difference.
Here’s everything you need to know about lipomas: what they are, how to recognise them, when they need treatment, and when a visit to your GP is the right move.
What Is a Lipoma?
A lipoma is a benign (not cancerous) fatty lump that is quite common. Lipomas can appear anywhere that you have fat cells, but most commonly grow on the neck, chest, back, shoulders, arms, and thighs.
In simpler terms: a lipoma is a small, enclosed pocket of fat cells that forms just beneath the skin. It isn’t a cyst (which is fluid-filled), it isn’t a tumour in the dangerous sense, and it isn’t contagious or caused by anything you did wrong.
Lipomas are small in size — about 1 to 3 cm — grow very slowly, and generally do not cause pain or any other symptoms. Most people only discover them by accident, noticing a lump while showering or when clothing rubs against it.
Lipomas form just beneath the skin and usually appear as small, soft lumps. While generally harmless, they may grow or cause discomfort, prompting individuals to seek removal.
What Does a Lipoma Feel Like?
The physical characteristics of a lipoma are quite distinctive and often enough for an experienced GP to diagnose one on examination alone:
- Soft and squishy — it compresses easily under light pressure
- Movable — it slides around freely under the skin when you press it
- Smooth edges — the borders feel defined, not jagged
- Painless in most cases — unless it’s pressing on a nearby nerve
- Slow-growing — it may barely change for years
A lipoma sits beneath the skin, within a fatty layer. The exact cause of lipomas is not always known. That said, genetics does play a role — if a parent or sibling has had lipomas, you’re more likely to develop them too. Some people develop a condition called familial multiple lipomatosis, where multiple lipomas grow over a lifetime.
Most often, you will only develop one or two lipomas. They’re most common in middle age, typically appearing between 40 and 60 years old, though they can develop at any age.
Are There Different Types of Lipomas?
Yes — though they all look and feel similar, there are several distinct variants:
Conventional lipoma — the most common type, made up of white fat cells. Soft, painless, and slow-growing.
Angiolipoma — contains both fat cells and blood vessels. Angiolipomas are known for being quite painful. If your lump hurts, this type is more likely.
Fibrolipoma — contains fibrous connective tissue mixed with fat. Slightly firmer than a conventional lipoma.
Deep lipoma — grows inside the body rather than just under the skin. If developed deep inside the body, a lipoma can press against an organ or nerve, causing related symptoms — for example, a lipoma of the intestine can cause bowel obstruction.
The specific type can only be confirmed through imaging or pathology after removal, but your GP can assess which type is most likely based on the lump’s location, feel, and your history.
Is a Lipoma Dangerous? Could It Be Cancer?
This is the question most people want answered, and the reassuring answer is: almost certainly not.
Lipomas are benign (not cancerous) and are quite common. Most lipomas are small and don’t cause any complications.
However, there is one important exception worth knowing about. There’s a very small chance that a lump resembling a lipoma may not be a lipoma and is actually a cancerous lump. These cancerous tumours are called liposarcomas and are found in the fatty tissues of the body. Liposarcomas are often painful, rapidly growing, and don’t move under the skin.
Whether the lump is a lipoma or a liposarcoma can be determined using a biopsy, an MRI, or a CT scan. These tests can be arranged by your GP.
The key warning signs that a lump needs urgent GP assessment:
- It is growing rapidly (over weeks, not years)
- It is painful or tender when you haven’t knocked it
- It feels hard or firm rather than soft and rubbery
- It doesn’t move freely under the skin
- The skin over it looks red, inflamed, or discoloured
- You feel generally unwell
If a lump has any of these features, see your GP promptly. A straightforward lipoma will have none of them.
When Is Lipoma Removal Necessary?
Here’s the honest answer most people need: most lipomas do not need to be removed unless they are painful.
That said, there are several clear circumstances where removal is the right decision — either medically necessary or entirely reasonable based on quality of life:
1. It Is Causing Pain or Discomfort
Treatment for lipomas is required if it becomes painful or restricts movement, or causes an embarrassing lump. An angiolipoma (the blood vessel-containing type) is particularly likely to cause discomfort, as is any lipoma that has grown large enough to press against a nerve.
2. It Is Growing
A lipoma that has been stable for years and suddenly starts growing warrants assessment. Rapid growth is never normal for a benign lipoma and needs investigation to rule out other causes.
3. It Is Affecting Daily Life
Lipomas on the neck, upper back, or under the arms can rub against clothing, affect posture, or interfere with movement — especially if they reach 3–5 cm or larger. Removal in these cases is medically reasonable and typically covered by Medicare.
4. You Are Uncertain About the Diagnosis
Many patients choose lipoma removal for peace of mind or quality-of-life reasons. If you’ve had a lump assessed and your GP believes it’s a lipoma but recommends removal to confirm via pathology, this is standard and sensible practice — especially if it has any atypical features.
5. Cosmetic Concerns
You may also choose to have a lipoma removed if you are bothered by how it looks. A visible lipoma on the forehead, neck, or forearm can affect confidence and self-image. Cosmetic removal is a legitimate reason — just note that in this case, it may not be Medicare-rebatable and a gap fee may apply.
How Is a Lipoma Removed?
Surgical excision is the primary treatment. This involves carefully removing the lipoma under local anaesthetic through a small incision. The goal is to remove the lump and surrounding capsule to help prevent regrowth. Procedures are performed in-clinic with minimal downtime.
Here’s what to expect at a GP minor procedure clinic like Central Health Clinic:
Step 1 — Consultation and assessment. Your GP examines the lump, reviews your history, and confirms the likely diagnosis. They’ll discuss options and, if proceeding, explain the procedure, expected scarring, and aftercare.
Step 2 — Local anaesthetic. The area is numbed with a local anaesthetic injection. You may feel pressure but should not feel sharp pain during the procedure.
Step 3 — Excision. A small incision is made in the skin, and the lipoma — ideally along with its surrounding capsule — is carefully removed. Removing the capsule reduces the chance of the lipoma growing back.
Step 4 — Closure and dressing. The wound is closed with sutures and covered with a dressing. Most patients can resume light activities the same day.
Step 5 — Pathology (if recommended). The removed tissue is often sent to a pathology lab for examination — a routine step that confirms the diagnosis with certainty.
The benefit of surgical removal is that recurrence after surgery is uncommon, although surgical removal of a lipoma may result in scarring and bruising.
For large or deep lipomas, referral to a specialist or hospital-based day surgery may be required. Your GP will advise you on the most appropriate pathway.
What About Lipoma Removal and Medicare in Australia?
Whether your lipoma removal is covered by Medicare depends on the clinical indication — meaning the medical reason for removal.
If the lipoma is causing pain, restricting movement, growing, or needs biopsy for diagnostic certainty, Medicare will typically contribute to the cost. If removal is purely cosmetic, it is generally not Medicare-rebatable and a private fee will apply.
The best approach is to discuss this openly with your GP at your consultation. At Central Health Clinic in Sunshine, our GPs can assess your lipoma, discuss your options, and clearly explain what costs to expect before you proceed.
Lipoma vs. Cyst: What’s the Difference?
People often confuse lipomas with sebaceous cysts. Here’s a quick comparison:
| Lipoma | Sebaceous Cyst | |
|---|---|---|
| Contents | Fat cells | Fluid or keratin |
| Feel | Soft, rubbery | Firmer, dome-shaped |
| Location | Beneath the skin in fat layer | Within the skin layer |
| Visible opening | None | Sometimes has a small dark punctum |
| Can become infected? | Rarely | Yes — can become red and painful |
| Treatment | Excision if needed | Excision if needed |
Both are benign. Both can be assessed and removed by a GP. If you’re unsure which you have, a GP consultation will clarify this quickly.
When Should You See a GP About a Lump?
The general rule: any new lump you haven’t had assessed should be checked by a GP. This is especially true if:
- The lump appeared suddenly or is growing quickly
- It’s painful, tender, or warm to touch
- It feels hard, irregular, or fixed (doesn’t move)
- You’re over 40 and it’s a new growth
- It’s in an unusual location (groin, armpit, abdomen)
- You have a family or personal history of cancer
Even if you suspect it’s “just a lipoma,” a GP assessment gives you a confirmed diagnosis and peace of mind — and takes less than 10 minutes.
Frequently Asked Questions
Can a lipoma turn into cancer? True lipomas do not transform into cancer. However, a rare type of cancerous tumour called a liposarcoma can occasionally be mistaken for a lipoma. Liposarcomas are typically painful, fast-growing, and don’t move freely under the skin — the opposite of a typical lipoma. Any lump with these features should be assessed promptly by a GP.
Does lipoma removal hurt? The procedure itself is performed under local anaesthetic, so you shouldn’t feel sharp pain — only pressure or movement. Mild soreness at the site for a few days afterward is normal and easily managed with standard pain relief.
Will my lipoma grow back after removal? Recurrence is uncommon when the lipoma — including its surrounding capsule — is fully removed. In rare cases, a small amount of remaining tissue can lead to regrowth, but this is the exception rather than the rule.
Can my GP remove a lipoma, or do I need a specialist? Many lipomas can be removed by an experienced GP in a clinic setting under local anaesthetic — particularly smaller, superficial ones. Larger, deeper, or more complex lipomas may require referral to a general surgeon. Your GP will advise the most appropriate option for your specific situation.
Is lipoma removal covered by Medicare in Australia? It depends on the clinical reason. Removal for medical reasons — pain, growth, diagnostic uncertainty — is typically Medicare-rebatable. Purely cosmetic removal generally is not. Discuss this with your GP at your initial consultation.
How long is the recovery after lipoma removal? Most people can resume normal light activity the same day. Avoid strenuous exercise and heavy lifting for 1–2 weeks. Sutures are typically removed within 7–10 days. Bruising and mild swelling around the site usually settle within a week.
The Bottom Line
A lipoma is almost always harmless — a benign, slow-growing collection of fat cells that most people can safely monitor without treatment. But “harmless” is not the same as “ignore it.”
Any new lump deserves a GP assessment to confirm it’s what it appears to be, rule out anything more serious, and give you a clear plan. If it’s causing pain, growing, interfering with daily life, or simply bothering you, removal is a straightforward, low-risk procedure that most experienced GPs can perform in-clinic.
