Why Do I Suddenly Have Lipomas?
Discovering one or more new lumps under the skin can be unsettling, particularly if they seem to have appeared over a short period of time. Many people report that lipomas feel as though they have developed suddenly, even though they are told these growths are slow-growing.
In most cases, the appearance of lipomas is benign and not a sign of serious illness. This article explains why lipomas may seem to appear suddenly, what factors are associated with their development, and when medical assessment is advised.
What Is a Lipoma?
A lipoma is a benign, non-cancerous growth composed of fatty tissue. Lipomas usually develop just beneath the skin and are typically soft, smooth, and mobile when touched. They most commonly occur on the arms, shoulders, back, abdomen, and thighs, although they can appear almost anywhere on the body.
Lipomas are the most common benign soft tissue tumour in adults. Studies suggest they affect approximately 1% of the population. They can occur at any age but are most frequently identified in people between 40 and 60 years old.
Why Lipomas Can Appear to Develop Suddenly
Although lipomas grow slowly, there are a number of well-recognised reasons why they may appear to develop suddenly.
They Often Go Unnoticed for a Long Time
Lipomas usually enlarge gradually over months or years. Many remain unnoticed until they reach a size where they become easier to feel or see. Weight loss, changes in muscle tone, or reduced surrounding fat can make an existing lipoma more noticeable.
Increased Awareness After Finding One Lump
Once a person discovers a single lipoma, they often become more aware of their body and begin checking other areas. This frequently leads to the discovery of additional lipomas that were already present, creating the impression that multiple lumps have appeared at the same time.
Natural Changes With Age
Lipomas become more common with increasing age. Changes in fat distribution, connective tissue, and skin elasticity can make underlying lumps more apparent over time, even if they have been present for years.
Factors Associated With Developing Lipomas
The exact cause of lipomas is not fully understood. However, several factors are recognised to be associated with their development.
Genetic Predisposition
There is a recognised genetic component in some individuals. Lipomas can run in families, and a condition known as familial multiple lipomatosis is associated with the development of multiple lipomas over time. In these cases, new lipomas may appear periodically throughout adulthood.
Minor Injury or Trauma
Some lipomas are first noticed at the site of a previous minor injury, such as a knock or bruise. Trauma is not considered a direct cause of lipoma formation, but it may draw attention to an existing lump or, in susceptible individuals, be associated with local changes in fatty tissue.
Hormonal and Metabolic Factors
Some studies have identified an association between lipomas and metabolic conditions. In large observational analyses, adults with lipomas were found to have a higher prevalence of metabolic traits such as dyslipidaemia, hypertension, obesity, and type 2 diabetes compared with the general population.
These findings suggest a possible link between lipoma development and underlying metabolic factors, but they do not establish a direct cause-and-effect relationship.
Is It Normal to Develop Multiple Lipomas?
Yes. Many people develop more than one lipoma during their lifetime. Having multiple lipomas does not increase the risk of cancer. Each lump should still be assessed individually, particularly if it is new, growing, or different from others.
Studies suggest that multiple lipomas are present in approximately 5% to 10% of affected individuals.
When Should You Be Concerned?
While lipomas are benign, medical review is recommended if a lump:
- Is growing rapidly
- Becomes painful or tender
- Feels firm, irregular, or fixed in place
- Is located deep in the body, especially in the thigh or abdomen
- Has not previously been assessed
These features do not automatically indicate cancer, but they warrant assessment to exclude rarer conditions such as liposarcoma.
Do Lipomas Need Treatment?
Most lipomas do not require treatment and can safely be left alone if they are not causing symptoms. Many remain stable for years without any impact on health.
Lipoma Removal on the NHS
The NHS may offer lipoma removal when there is medical concern, such as diagnostic uncertainty, rapid growth, pain, functional impairment, or suspicion of an alternative diagnosis. However, lipomas that are benign and not causing medical problems will not be removed by the NHS.
Private Lipoma Removal
As a result, many patients choose private lipoma removal for cosmetic reasons or to avoid long waiting times. Private treatment allows timely assessment, clear pricing, and removal.
Lipoma Removal at Waverley Park Minor Surgery Clinic
Lipoma removal at Waverley Park Minor Surgery Clinic is a clinician-led process that begins with careful assessment and continues through to definitive treatment and follow-up. The emphasis throughout is on accurate diagnosis, patient comfort, and safe surgical care.
Initial Consultation and Assessment
Your initial consultation is an essential first step and focuses on confirming the diagnosis and determining whether lipoma removal is appropriate.
During the consultation, the doctor will:
- Examine the lump to assess its size, location, depth, mobility, and consistency
- Review your medical history and any symptoms, such as discomfort or growth
- Discuss your reasons for seeking removal, including cosmetic or practical concerns
- Consider whether further investigation, such as an ultrasound scan, is required
If the lump is consistent with a lipoma and suitable for removal, the surgical excision procedure will be explained in detail. This includes discussion of the benefits and risks, expected healing, scarring, and aftercare, allowing you to make an informed decision about treatment.
If there is any uncertainty about the diagnosis, you may be advised to undergo further investigation or be referred back to your GP for additional assessment.
How the Lipoma Removal Procedure Is Performed
Lipoma removal is usually carried out as a minor surgical procedure under local anaesthetic and is performed in a calm clinical setting.
The procedure typically involves:
- Local anaesthetic, which numbs the area to ensure comfort throughout
- A small incision made over the lipoma
- Careful surgical excision, where the fatty tissue is gently dissected and removed, usually in one piece
- Wound closure with sutures, with attention paid to minimising scarring and supporting good healing
The procedure usually takes 30 to 60 minutes, depending on the size and location of the lipoma.
Aftercare and Pathology Testing
Following removal, a sterile dressing is applied, and you are given clear written aftercare instructions. Most patients experience only mild soreness or bruising, which settles within a few days.
All removed tissue is routinely sent to a local pathology laboratory for microscopic examination to confirm the diagnosis. The result is communicated to your GP, ensuring continuity of care and providing definitive reassurance.
Follow-up is arranged if required, including suture removal where appropriate.

Frequently Asked Questions
Can stress or lifestyle cause lipomas?
There is no evidence that stress, diet, exercise habits, or lifestyle directly cause lipomas. While overall health is important, lipomas develop independently of stress levels or lifestyle choices. Maintaining a healthy lifestyle will not prevent lipomas from forming or cause existing lipomas to disappear.
What happens if a lipoma is not removed?
If a lipoma is not removed, it will usually remain stable or grow very slowly over time. Many lipomas cause no symptoms and can safely be left alone without any risk to health. In some cases, a lipoma may gradually increase in size or become uncomfortable depending on its location, at which point reassessment may be helpful.
How fast do lipomas typically grow?
Lipomas usually grow very slowly, often over months or years. Many show little or no change for long periods. Rapid growth is not typical of lipomas and should be assessed by a clinician to confirm the diagnosis and exclude other conditions.
What other conditions are linked to lipomas?
Lipomas are most often isolated findings, but in some individuals, they are associated with inherited conditions such as familial multiple lipomatosis, where multiple lipomas develop over time. Lipomas have also been observed more frequently in people with certain metabolic conditions, although this represents an association rather than a direct cause.
What increases the risk of developing lipomas?
Factors associated with an increased likelihood of developing lipomas include increasing age, genetic predisposition, and a family history of lipomas. Lipomas can occur in people of all body types and are not caused by being overweight. Having one lipoma does not necessarily mean more will develop.
