Lipoma
Table of Contents
Lipomas are typically benign growths that can affect various parts of the body, leading to concerns about their origin, impact, and management. Identifying the causes behind these fatty tumours is crucial for understanding why they develop. Recognising the symptoms associated with lipomas, such as their appearance and any potential discomfort they may cause, is key for timely intervention. Furthermore, exploring the available solutions, from non-invasive treatments to surgical options, can help in effectively addressing lipomas and alleviating any related issues. This guide aims to provide a thorough overview of lipomas, offering insights into their causes, symptoms, and potential solutions for those seeking to understand and manage these growths.
What’s a lipoma?
A lipoma is a benign (non-cancerous) tumour composed of fat tissue. It typically appears as a soft, doughy lump under the skin that is easily movable when touched. Lipomas are usually slow-growing and can vary in size, ranging from as small as a pea to several centimetres in diameter. They can develop anywhere on the body where fat cells are present but are most commonly found on the neck, shoulders, back, abdomen, arms, and thighs. While lipomas are generally painless and harmless, they can sometimes cause discomfort if they press on nearby nerves or if they become large enough to be noticeable or bothersome. Most lipomas do not require treatment unless they cause pain, discomfort, or cosmetic concerns.
How common are lipomas?
Lipomas are relatively common, affecting approximately 1 in 1,000 people. They can occur at any age but are most frequently diagnosed in middle-aged adults, typically between the ages of 40 and 60. While both men and women can develop lipomas, they tend to be slightly more prevalent in men. Additionally, lipomas can be hereditary, meaning that if you have a family member with lipomas, you may be more likely to develop them as well. These benign tumours are among the most common types of soft tissue tumours found in adults. Despite their prevalence, many people may not notice smaller lipomas, leading to underreporting of cases.
What are the symptoms of a lipoma?
The primary symptom of a lipoma is the presence of a soft, doughy lump under the skin. Here are the key symptoms to look out for:
Painless Lump
Most lipomas are painless. However, if they press on nearby nerves or contain many blood vessels, they can cause discomfort or tenderness.
Soft and Movable
Lipomas are usually soft to the touch and easily movable under the skin when pressure is applied. This is due to their fatty composition.
Slow Growth
Lipomas grow slowly over several months or years. They typically remain small, but in some cases, they can grow to a size of several centimetres in diameter.
Size Variation
Lipomas can range in size from as small as a pea to larger than a golf ball. Most lipomas are less than 5 centimetres in diameter, but they can occasionally grow larger.
Location
Lipomas can develop anywhere on the body where fat cells are present, but they are most commonly found on the neck, shoulders, back, abdomen, arms, and thighs.
Shape and Consistency
Lipomas are usually round or oval in shape with a rubbery consistency. They can feel doughy and are not fixed in place, meaning they can move slightly under the skin.
Multiple Lipomas
Some individuals may develop multiple lipomas, a condition known as lipomatosis. This can be hereditary and result in numerous lumps scattered across different parts of the body.
Surface Appearance
The skin over the lipoma usually appears normal. Unlike cysts, lipomas do not typically cause skin discoloration or changes in texture.
Where do lipomas grow?
Lipomas can develop anywhere on the body where fat cells are present. However, they are most commonly found in certain areas. Here are the most frequent locations for lipomas:
Neck and Shoulders
Lipomas often appear on the neck and shoulders. These areas are common sites due to the presence of subcutaneous fat and are easily noticeable.
Back
The back, especially the upper back, is another frequent location for lipomas. They can vary in size and may be felt as soft lumps under the skin.
Abdomen
Lipomas can form on the abdomen, where they are often detected during routine physical examinations or if they become large enough to be seen or felt.
Arms and Thighs
The arms and thighs are also common sites for lipomas. They may appear as soft, movable lumps that can cause cosmetic concerns or discomfort, especially if they press on nerves.
Forearms
Lipomas on the forearms are less common but can still occur. They can affect the appearance and, in some cases, the function of the arm if they grow large enough.
Buttocks
Lipomas can develop on the buttocks, where they may be felt as soft lumps under the skin. They are usually painless but can cause discomfort when sitting or during physical activities.
Legs
Lipomas can appear on the legs, particularly on the thighs and calves. They are usually benign and do not interfere with movement.
Chest
The chest area, including the breast tissue in both men and women, can also be a site for lipomas. They may be mistaken for other types of lumps, so a proper diagnosis is essential.
Face
Although less common, lipomas can develop on the face. When they do, they are often smaller and may cause cosmetic concerns due to their visibility.
Hands and Feet
Lipomas on the hands and feet are rare but possible. Due to the limited amount of subcutaneous fat in these areas, lipomas may cause more noticeable discomfort or functional issues.
What causes a lipoma?
The exact cause of lipomas is not well understood, but several factors are believed to contribute to their development. Here are some of the key factors associated with the formation of lipomas:
Genetic Factors
Genetics plays a significant role in the development of lipomas. If you have a family member with lipomas, you are more likely to develop them, suggesting a hereditary predisposition. Certain genetic conditions, such as familial multiple lipomatosis, increase the likelihood of developing multiple lipomas.
Age
Lipomas are most commonly diagnosed in middle-aged adults, typically between the ages of 40 and 60. However, they can occur at any age, including in children and the elderly.
Trauma
Some studies suggest that minor injuries or trauma to a specific area can trigger the growth of a lipoma. This is known as post-traumatic lipoma. However, the evidence supporting this theory is not conclusive.
Medical Conditions
Certain medical conditions are associated with the development of lipomas. These include:
- Adiposis Dolorosa (Dercum’s Disease): A rare disorder characterised by painful lipomas.
- Gardner Syndrome: An inherited condition that causes multiple growths, including lipomas, as well as other types of tumours.
- Madelung’s Disease: A disorder involving the abnormal accumulation of fat in the upper body, including multiple lipomas.
Metabolic Factors
Some research suggests a link between lipomas and metabolic disorders, such as diabetes and hyperlipidemia (high levels of fat in the blood). However, this association is not well-established.
Hormonal Factors
Hormonal changes, particularly those involving oestrogen, may influence the development of lipomas. This is observed in some cases where lipomas become more prominent during pregnancy or menopause.
Obesity
While lipomas can occur in individuals of any body weight, there may be a higher prevalence in people who are overweight or obese. However, lipomas themselves are not caused by obesity and can develop in individuals with normal body weight.
How are lipomas diagnosed?
Diagnosing a lipoma typically involves a combination of physical examination, patient history, and imaging studies. Here’s a detailed look at the process:
1. Clinical Examination
Physical Examination
A healthcare provider will begin by conducting a thorough physical examination of the lump. They will assess its size, shape, texture, and mobility. Lipomas are usually soft, doughy, and easily movable under the skin, which helps distinguish them from other types of lumps.
Symptom Evaluation
The healthcare provider will ask about any symptoms associated with the lump, such as pain or discomfort, changes in size, and how long it has been present.
2. Medical History Review
Patient History
A comprehensive review of your medical history is essential. This includes discussing any family history of lipomas or other tumours, previous medical conditions, and any recent injuries or trauma to the affected area.
Lifestyle Factors
Information about your lifestyle, such as diet, exercise habits, and any significant weight changes, may also be relevant in understanding the development of the lipoma.
3. Imaging Studies
Ultrasound
An ultrasound is often the first imaging test used to evaluate a lipoma. It helps determine the composition of the lump and differentiate it from other types of growths, such as cysts or malignant tumours. Ultrasounds provide a clear image of the lump’s internal structure and can confirm the presence of fat cells.
MRI (Magnetic Resonance Imaging)
For a more detailed evaluation, an MRI may be recommended. MRI scans provide high-resolution images of the soft tissues and can help assess the size, depth, and exact location of the lipoma. MRI is particularly useful for larger lipomas or those located in deeper tissues.
CT Scan (Computed Tomography)
A CT scan can also be used to obtain detailed cross-sectional images of the lump. It helps in assessing the lipoma’s relationship with surrounding structures and is particularly useful for deep-seated lipomas.
4. Biopsy
Fine Needle Aspiration (FNA)
In some cases, a fine needle aspiration may be performed to extract a small sample of cells from the lump. The sample is then examined under a microscope to confirm the diagnosis. FNA is a minimally invasive procedure that helps differentiate a benign lipoma from other types of tumours, including liposarcoma (a rare cancerous tumour).
Core Needle Biopsy
If the FNA results are inconclusive, a core needle biopsy may be performed. This involves using a larger needle to obtain a more substantial tissue sample for analysis.
5. Differential Diagnosis
Rule Out Other Conditions
The healthcare provider will consider other potential causes of the lump, such as cysts, fibromas, or malignant tumours, and use the diagnostic information to rule out these conditions. Lipomas are typically benign, but it is important to ensure that the lump is not something more serious, such as a liposarcoma.
6. Follow-Up
Monitoring
For asymptomatic lipomas that do not cause discomfort or cosmetic concerns, regular monitoring may be recommended. This involves periodic check-ups to ensure the lipoma does not grow or change significantly.
Patient Education
The healthcare provider will educate the patient about the nature of lipomas, their benign nature, and the treatment options available if the lipoma becomes symptomatic or problematic.
What are the types of lipomas?
Lipomas are generally categorised based on their specific characteristics and the types of tissues they contain. Understanding the different types of lipomas can help in diagnosing and determining the most appropriate treatment. Here are the main types of lipomas:
1. Conventional Lipoma
Conventional lipomas are the most common type, consisting primarily of mature fat cells. These lipomas are characterised by their soft, doughy texture and their ability to move under the skin. Typically painless, conventional lipomas can become uncomfortable if they press on nearby nerves. They are often easily detected due to their superficial placement and distinct feel.
2. Fibrolipoma
Fibrolipomas are a variant of lipomas that contain both fat and fibrous tissue. The presence of fibrous tissue gives these lipomas a firmer consistency compared to conventional types. Despite their increased firmness, they remain generally soft and movable under the skin. This mix of fat and fibrous tissue can make them slightly more distinct from typical lipomas in terms of texture.
3. Angiolipoma
Angiolipomas are characterised by the presence of fat cells interspersed with numerous small blood vessels. This type of lipoma is often painful or tender, especially when pressed. The vascular nature of angiolipomas makes them more likely to cause discomfort compared to other lipoma types. The pain associated with angiolipomas can be a key differentiator in diagnosing this variant.
4. Spindle Cell Lipoma
Spindle cell lipomas contain fat cells alongside spindle-shaped (elongated) cells. They are commonly found on the back, neck, and shoulders, and are often seen in middle-aged men. These lipomas are noted for their firm, rubbery texture. The unique cellular composition of spindle cell lipomas differentiates them from more typical, softer lipomas.
5. Pleomorphic Lipoma
Pleomorphic lipomas are characterised by fat cells that vary in size and shape. Typically found in older men, these lipomas have an irregular shape and a firmer texture compared to conventional lipomas. The varied appearance of fat cells gives pleomorphic lipomas a distinctive look and texture, which can make them more noticeable or concerning.
6. Adenolipoma
Adenolipomas contain both fat and glandular (adenoid) tissue. This less common type of lipoma exhibits a unique texture and appearance due to the presence of glandular tissue mixed with fat. The glandular component can influence the lipoma’s overall feel and may affect its detection or diagnosis.
7. Myelolipoma
Myelolipomas are rare lipomas that include both fat and hematopoietic (blood-forming) tissue. Often discovered incidentally during imaging studies for unrelated conditions, these lipomas are typically found in the adrenal glands. Their presence is unusual, and their combination of fat and blood-forming tissue makes them unique among lipoma types.
8. Hibernoma
Hibernomas contain brown fat, which is metabolically more active than the white fat found in most lipomas. These rare lipomas are often located in areas with high brown fat concentrations, such as the neck and upper back. The presence of brown fat gives hibernomas a firmer and more vascular texture, distinguishing them from other lipoma types.
9. Intramuscular Lipoma
Intramuscular lipomas grow within the muscle tissue, which can cause pain or discomfort, especially during muscle movement. These lipomas are less visible compared to superficial lipomas and often require imaging studies for accurate diagnosis. Their location within muscle tissue can make them challenging to detect and manage.
10. Perineural Lipoma
Perineural lipomas surround a nerve or a group of nerves, which can lead to symptoms such as pain, numbness, or weakness in the affected area. These lipomas may require surgical intervention to alleviate nerve compression and relieve associated symptoms. The close proximity to nerves makes perineural lipomas distinct in their presentation and treatment needs.
11. Superficial Subcutaneous Lipoma
Superficial subcutaneous lipomas are located just beneath the skin, making them the most common and easily noticeable type. They are characterised by their soft, movable texture and are typically painless. Their superficial placement allows for easy detection and evaluation, often leading to straightforward management.
12. Deep Lipoma
Deep lipomas are located deeper within the body, often embedded in muscles or internal organs. These lipomas are less common and can be challenging to detect without imaging studies. The deeper location means they may cause symptoms based on their size and location, which can impact nearby structures and complicate diagnosis and treatment.
Treatment for lipomas?
Lipomas are typically benign and do not require treatment unless they cause discomfort, pain, or cosmetic concerns. However, when treatment is necessary, there are several options available. The choice of treatment depends on the size, location, symptoms, and patient preferences. Here are the main treatment options for lipomas:
1. Surgical Excision
Surgical excision is the most common and effective method for removing lipomas. This procedure involves making an incision over the lipoma and carefully excising the entire lump along with its capsule. It is typically performed under local anaesthesia for smaller lipomas and general anaesthesia for larger or deeper ones. Recovery is usually quick with minimal scarring, though patients might experience some discomfort and swelling for a few days. The effectiveness of surgical excision is high, offering a permanent solution with a low risk of recurrence.
Benefits
- Complete removal of the lipoma.
- Minimal risk of recurrence.
- Immediate relief from symptoms.
Considerations
- Potential for scarring, especially for larger lipomas.
- Requires a minor surgical procedure.
2. Liposuction
Liposuction is a less invasive option for removing lipomas, especially suitable for larger ones. The procedure involves making a small incision near the lipoma and inserting a cannula to suction out the fatty tissue. It is performed under local anaesthesia, offering a shorter recovery time compared to surgical excision. The procedure results in minimal scarring and generally causes less postoperative discomfort. While liposuction is effective in reducing the size of the lipoma, it may not remove all of the fatty tissue, which can lead to a higher chance of recurrence.
Benefits
- Less invasive than surgical excision.
- Minimal scarring.
- Shorter recovery period.
Considerations
- Higher risk of recurrence if not all the tissue is removed.
- May not be suitable for lipomas with a dense fibrous component
3. Steroid Injections
Steroid injections involve administering a corticosteroid solution directly into the lipoma to reduce its size. This less commonly used method typically requires a series of injections over several weeks. The procedure has minimal downtime, allowing patients to resume their normal activities immediately. While steroid injections can effectively reduce the lipoma’s size, they usually do not eliminate it completely, making it a less definitive solution compared to surgical options.
Benefits
- Non-surgical and minimally invasive.
- Can be effective for smaller lipomas.
Considerations
- Multiple treatment sessions may be required.
- May not completely eliminate the lipoma.
- Potential side effects of corticosteroids, such as skin thinning and discoloration.
4. Observation and Monitoring
Observation and monitoring involve keeping track of asymptomatic lipomas that do not cause discomfort or cosmetic concerns. The procedure consists of regular check-ups to ensure that the lipoma remains stable and does not exhibit significant growth or changes. This approach is effective for avoiding unnecessary interventions, as immediate treatment is not required unless the lipoma begins to cause problems.
Benefits
- Avoids unnecessary procedures.
- Suitable for small, asymptomatic lipomas.
Considerations
- Requires regular follow-ups.
- Intervention may be needed if the lipoma grows or becomes symptomatic.
5. Alternative Treatments
Cryotherapy
Cryotherapy involves freezing the lipoma with liquid nitrogen to destroy fat cells and cause the lump to shrink. During the procedure, the lipoma is exposed to extremely cold temperatures, leading to the death of the fat cells. Recovery is generally quick, with minimal downtime, although some discomfort may be experienced during the treatment. However, the effectiveness of cryotherapy is variable, and it is not commonly recommended due to its limited results and lower success rate compared to other treatment options.
Laser Therapy
Laser therapy uses concentrated laser energy to target and break down the fat cells within the lipoma. During the procedure, the laser is directed at the lipoma to reduce its size by causing the fat cells to break apart. Recovery is generally minimal, with patients experiencing little discomfort and requiring little downtime. However, laser therapy is still considered experimental and is not widely available or commonly used in standard practice due to its limited effectiveness and ongoing investigation into its long-term outcomes.
Prevention of lipoma
Preventing lipomas can be challenging due to their largely idiopathic nature; however, certain strategies might help reduce the risk of developing them:
Maintain a Healthy Weight
Obesity has been linked to an increased risk of lipomas. Adopting a balanced diet and engaging in regular physical activity can help manage weight and potentially reduce the likelihood of developing lipomas.
Avoid Excessive Alcohol Consumption
Some studies suggest that high alcohol intake might be associated with a higher risk of lipomas. Moderation in alcohol consumption can be beneficial for overall health and might help lower the risk.
Regular Exercise
Engaging in regular exercise helps maintain a healthy body weight and supports overall metabolic health, which could potentially minimise the risk of lipomas.
Monitor and Manage Chronic Conditions
Conditions such as metabolic syndrome and diabetes have been associated with an increased risk of lipomas. Managing these conditions through lifestyle changes and medical care may help reduce the risk.
Genetic Factors
While genetic predisposition plays a role in lipoma development, maintaining a healthy lifestyle may help mitigate the risk. Family history of lipomas cannot be altered, but overall health can still be optimised.
Minimise Trauma and Strain
Although not proven, avoiding excessive trauma or strain to areas where lipomas commonly occur might be beneficial, especially if there is a history of lipomas in those areas.
By incorporating these preventive measures, individuals can support their overall health and potentially reduce their risk of developing lipomas.

Lipoma Frequently Asked Questions
A lipoma is a benign, soft tumour made of fatty tissue. It is usually slow-growing and can appear anywhere on the body, though it is most commonly found on the upper back, arms, or thighs.
No, lipomas are benign tumours and are not cancerous. They are composed of mature fat cells and do not spread to other parts of the body.
The exact cause of lipomas is not fully understood, but factors may include genetic predisposition, trauma, or certain genetic conditions. They often appear spontaneously and can run in families.
Lipomas that cause discomfort, pain, or cosmetic concerns may require treatment. If a lipoma changes in size, shape, or causes symptoms, it’s important to consult a healthcare professional for evaluation.
Treatment options include surgical excision, liposuction, steroid injections, and observation. The choice depends on factors such as the lipoma’s size, location, and whether it is causing symptoms.
Lipoma removal is generally performed under local or general anaesthesia, so patients should not experience pain during the procedure. Some discomfort and swelling may occur during recovery, but it is usually manageable.
Recovery time varies depending on the method used. Surgical excision may require a few days to weeks for full recovery, while liposuction generally has a shorter recovery period. Post-procedure care and follow-up are essential for optimal healing.
While surgical excision is effective in removing lipomas, there is a small chance of recurrence. Liposuction may leave residual fat cells, leading to potential recurrence. Regular follow-up helps monitor and manage any changes.
Non-surgical options include steroid injections and cryotherapy. These methods can reduce the size of the lipoma but may not completely remove it. Laser therapy is also being explored but is not widely used.
There is no known way to prevent lipomas. Maintaining a healthy lifestyle may reduce the risk of certain conditions that could contribute to their development, but lipomas often occur without any identifiable cause.
Lipoma - The Takeaway
Lipomas, while typically benign and non-cancerous, can still cause concern due to their appearance or potential discomfort. Understanding the nature of lipomas—soft, movable lumps composed of fatty tissue—is essential for proper management. Treatment options range from surgical excision to less invasive methods like liposuction or steroid injections, each tailored to the lipoma’s characteristics and the patient’s needs. Regular monitoring may be sufficient for asymptomatic lipomas, while intervention is advised for those causing discomfort or cosmetic issues.
