Meta Description: Uncover the surprising triggers behind lipomas, explore the most effective treatment options, and find out when—or if—you should worry. Your complete guide to lipomas: Get the facts on what causes them, the latest treatment options, and expert insights—all in one place.
A lipoma is a soft, fatty growth that develops gradually, typically forming between the skin and the muscle beneath it. Although they might look unsettling at first, lipomas are harmless and almost never pose a medical threat. They’re typically soft, non-tender, and shift slightly when touched under the skin.
Soft and doughy consistency
Located just under the skin
Slow-growing
Usually less than 2 inches in diameter
Commonly appearing on the neck, shoulders, arms, back, belly, or even the upper legs, these marks settle where skin stretches or bears frequent pressure.
Painless
Round or oval in shape
Moveable under the skin
Small (usually less than 2 inches, but some can grow larger)
Though they aren’t life-threatening, understanding lipomas is essential so you can make informed decisions about treatment or removal, especially if the lump changes in size or starts to cause discomfort.
While the exact cause of lipomas is still unclear, researchers and medical experts have pinpointed several contributing factors that may lead to their development.
Genetics appears to play a strong role. If someone in your family has had lipomas, you may be more likely to develop them too. This condition is sometimes inherited, particularly in a condition called familial multiple lipomatosis.
Some people report developing a lipoma after an injury. While there’s no solid scientific proof to back this cause, it’s believed that trauma might trigger the growth of fat cells in unusual ways.
4. Certain Medical Conditions
There are some medical conditions associated with multiple lipomas, such as:
Adiposis dolorosa (Dercum’s disease)
Some metabolic disorders may increase your risk, including:
Madelung’s disease
Adiposis dolorosa
High cholesterol levels
These are rare conditions but are worth noting if you’re experiencing multiple growths.
Identifying a lipoma can be relatively simple. They’re usually noticed as painless, movable lumps under the skin. But like snowflakes, no two lipomas are alike—their symptoms shift depending on where they settle and how much space they claim.
A soft, squishy lump under the skin
Movement when touched
Typically painless, unless pressing on nerves or containing many blood vessels
Slow but steady growth
In some rare cases, lipomas can become painful, especially when located near nerves or blood vessels.
Not every soft lump is a lipoma, so it helps to know what symptoms to look out for. Lipomas are often spotted by chance during regular health checkups or when examining your body for something else.
Typical Symptoms Include:
A soft, doughy feel under the skin
Mobile lump (moves slightly when pressed)
Painless (unless pressing on nerves or blood vessels)
Usually under 2 inches but can grow over time
They typically appear on areas like the neck, shoulders, back, arms, thighs, or midsection.
While lipomas are generally benign, consult a doctor if:
The lump grows rapidly
Pain or discomfort arises
It becomes hard or immobile
Skin over the lump becomes discolored
These may indicate a liposarcoma, a rare form of cancer that mimics lipomas.
Although all lipomas are fatty tumors, there are different types based on the tissue found inside:
The most common type
Composed mostly of mature fat cells
Contains both fat and fibrous tissue
Feels firmer to the touch
Contains blood vessels
Can be painful
Contains fat and muscle tissue
A rare type found mostly in the neck and shoulders of older men
Derived from brown fat
Very rare
Doctors can usually diagnose a lipoma by its texture, shape, and mobility.
Ultrasound: Helps distinguish a lipoma from a cyst.
MRI or CT scan: Useful if the lump is large, deep, or causing symptoms.
If there's any doubt about the nature of the growth, a small sample may be taken and analyzed to rule out malignancy.
Most lipomas don’t need treatment unless they’re painful, growing, or bothersome for cosmetic reasons.
Many people choose to simply monitor their lipomas if they’re small and not causing problems.
The most common treatment.
Done under local anesthesia.
Recommended for lipomas that are large, painful, or growing.
Fat is sucked out through a thin tube.
Less invasive than surgery but may not remove all the tissue.
It can help shrink the lipoma, but it typically doesn’t get rid of it completely.
Note: Natural or home remedies like turmeric or apple cider vinegar have no scientific backing and are not recommended for treating lipomas.
| Feature | Lipoma | Liposarcoma |
|---|---|---|
| Growth Speed | Slow | Rapid |
| Pain | Usually painless | May be painful |
| Mobility | Mobile under skin | Often fixed |
| Cancer Risk | Benign | Malignant |
Effect your appearance
Cause minor physical discomfort
Require surgical removal for relief
Your doctor might suggest imaging tests periodically to ensure there are no unexpected changes.
Unfortunately, you can’t always prevent lipomas—especially if you have a genetic predisposition. However, maintaining a healthy lifestyle may reduce risk factors:
Eat a balanced diet low in saturated fat
Exercise regularly
Maintain a healthy weight
Manage your cholesterol
Avoid unnecessary trauma to soft tissue areas
Most lipomas aren’t dangerous, but medical advice is recommended if:
The lump is growing quickly
It becomes painful
There are multiple lumps
The area becomes red or swollen
That mysterious lump under your skin—could it be a harmless lipoma, or is it something more?
To confirm the diagnosis, your doctor might suggest a biopsy or imaging scans.
Lipomas are usually diagnosed through physical examination, but additional diagnostic tools may include:
Ultrasound: To check the nature of the lump
MRI or CT scan: If the lipoma is deep or painful
Biopsy: To rule out liposarcoma (a rare cancerous tumor)
When a lipoma isn’t painful or affecting your appearance, treatment usually isn’t needed. However, many choose to have them removed for various reasons.
The most common treatment is minor surgery. A surgeon cuts out the lipoma under local anesthesia. It’s a quick and effective solution with a low chance of recurrence.
For larger lipomas, liposuction may be used. Using a precise needle or syringe, the fatty deposit is gently vacuumed out through a tiny incision—like removing the filling through a pinhole in a pillow. However, this method may not remove the entire capsule, which could lead to recurrence.
While a steroid injection can shrink a lipoma down to size, don’t expect it to pull a full vanishing act—these stubborn lumps rarely disappear completely with this treatment. This method doesn’t involve surgery and is typically reserved for treating smaller lipomas.
While there's limited scientific backing for natural treatments, some people explore home remedies to manage lipomas. Approach these methods carefully and be sure to consult a medical expert before depending on them.
Turmeric: Believed to have anti-inflammatory properties
Castor oil: Applied topically to soften the lump
Apple cider vinegar: Claimed to reduce fat deposits (though not clinically proven)
⚠️ Be sure to check with your healthcare provider before attempting any home treatments.
A common concern is whether lipomas can become cancerous. The good news? Lipomas do not turn into cancer. However, it's essential to differentiate between a lipoma and a liposarcoma, a rare cancerous tumor that may appear similar at first.
While you can't exactly put up a 'No Lipomas Allowed' sign on your body—especially when genetics are calling the shots—there's no proven prevention playbook for these fatty deposits. However, maintaining overall good health may help reduce risks.
Eat a balanced diet
Limit alcohol consumption, particularly if you have conditions such as Madelung's disease.
Maintain a healthy weight
Exercise regularly
Keep track of new skin changes
Most people with lipomas live normal, healthy lives. If the lump is not growing or causing pain, it can often be left alone. However, always keep an eye on it and report any changes to your healthcare provider.
No, lipomas are benign and generally harmless. They rarely require medical treatment unless bothersome.
Lipomas grow slowly over months or even years and typically stay under 2 inches wide.
There's no proven way to shrink existing lipomas through diet. However, healthy habits can support overall skin and tissue health.
Got a troublesome lipoma that's cramping your style—literally? If it's causing pain or putting limits on your movement, your insurance might just foot the bill for its eviction. Cosmetic removals are typically not covered.
There’s no surefire prevention, especially with a genetic predisposition. However, maintaining good health can help.
Lipomas are non-cancerous lumps made of fat that develop gradually and typically don’t cause pain.
Genetics, age, and certain medical conditions may increase your risk.
Surgical removal is the most effective treatment if needed.
While lipomas aren’t cancerous, it’s still essential to get them checked by a doctor.
Healthy lifestyle choices may help reduce risk or recurrence.
In most cases, lipomas are nothing to worry about. They’re common, benign, and treatable. However, if a lump is growing, painful, or just concerning, don’t hesitate to consult a medical professional. Knowing what to look for and understanding your options empowers you to make the best decisions for your health.
Have you recently discovered a lump under your skin? Don’t ignore it—get a professional evaluation to determine whether it’s a lipoma and what your treatment options are. Stay informed and take proactive steps for your peace of mind and well-being.
