Main
- Lipoma — a benign tumour of fatty tissue: it grows slowly, does not invade neighbouring structures and does not spread through the body.
- Typical signs: a soft round nodule under the skin, mobile when palpated, usually painless and growing unnoticed.
- Urgent visit to a doctor: if it grows quickly, becomes denser, painful or the skin over the formation changes colour.
- Examination: examination and palpation, ultrasound, for deep-lying tumours — tomography, if in doubt — biopsy.
- A surgeon manages a lipoma: if the picture is unclear, a dermatovenereologist is involved; if there is no relevant specialist — a physician.
What is a lipoma
A lipoma is a benign growth made of fatty tissue, which is most often felt as a soft, mobile lump under the skin. Below we look at what such a growth is, why it develops and who is affected more often.
What happens in the body
A lipoma forms from fat tissue cells which, for reasons that are not fully understood, begin to divide and accumulate in one place. These cells retain the properties of ordinary fat, so the lump stays soft and easily moves under the fingers. Such a growth enlarges slowly, sometimes hardly changing in size for years, and usually causes no pain. Since the tissue is benign, it does not grow into neighbouring structures and does not spread through the body. It is most often noticed by chance — when feeling an area of skin or during an examination for another reason. Even if the lump stays in one place for a long time, it does not turn into a malignant tumour. If the growth changes in size or starts to get in the way, it is sensible to show it to a doctor rather than trying to treat it yourself.
What causes it to develop
- Hereditary predisposition: a tendency to develop such lumps is often passed down in families, so if close relatives have had them, the risk is higher.
- Disorders of fat metabolism: if metabolism in fatty tissue works inconsistently, cells may accumulate locally and form a lump.
- Hormonal changes: a shift in hormonal balance can trigger the growth of the formation, although no direct link to a specific hormone has been established.
- Injury or constant pressure: a bruise, pressure from a belt or tight clothing in one place sometimes precedes the appearance of the lump.
- Age-related changes in tissues: over the years the structure of subcutaneous fat changes, and this may create conditions for the formation of such growths.
- Practical conclusion: none of these factors acts on its own, so looking for a single cause usually makes no sense.
Who is affected more often
Lipomas occur in people of different ages, but they are more often found in adults than in children. In women such lumps are found somewhat more often than in men, although there is no noticeable difference in how the process develops. Hereditary cases usually appear earlier and may be multiple, whereas single growths often appear in adulthood. People who are overweight and have disorders of fat metabolism encounter them more often, but no direct dependence on diet and lifestyle can be traced. Hormonal changes play a certain role, so lumps are sometimes first noticed during periods when the balance shifts. Injuries and constant pressure on one area of skin also increase the likelihood of a growth appearing in that particular place. If a lump has appeared, it is worth showing it to a doctor to make sure it is benign and not to miss other changes.
What symptoms can there be?
A lipoma is noticed as a soft nodule under the skin that moves easily when pressed and is usually painless. A simple assessment of its features helps to understand when such a growth requires a routine visit to a doctor and when urgent help is needed.
How it is noticed at the very beginning
A lipoma is most often discovered by chance, when a person runs a hand over the body and feels a small rounded growth under the skin. It feels like a soft nodule that moves freely under the fingers and causes almost no discomfort. Because there is no pain, such findings are often put down to fatigue, a stiff muscle or simply a feature of the physique. Over time the growth may slowly enlarge, but this growth is so gradual that it is noticed only months later. If the lipoma lies deeper, in the muscles or internal organs, it cannot be felt, and then it is found by chance during an examination for another reason. In such cases it can press on the surrounding tissues and cause unpleasant sensations, which are also easily mistaken for overwork. Therefore, with any unusual nodule it is sensible to see a doctor without waiting for it to start getting in the way.
Features that occur most often
- Soft nodule under the skin: the growth feels yielding and rounded rather than hard, which distinguishes it from dense structures.
- Mobility when felt: a lipoma moves easily under the fingers from side to side, because it is not fused with the skin and deeper-lying tissues.
- Painlessness in most cases: pressing usually does not cause pain, and that is precisely why a person may pay no attention to the finding for years.
- Slow growth: the size increases gradually, imperceptibly to the person themselves, and it becomes noticeable only after a long time.
- Discomfort when pressing on nearby tissues: if the growth lies deeper, it can press on the surrounding structures and cause unpleasant sensations.
When to seek help urgently
Examinations and tests
Examination for a lipoma begins with inspection and palpation of the formation, and additional methods are used only to clarify its borders and depth. Below is a breakdown of which tests are used and what each of them shows.
How the examination begins
A lipoma is usually recognised already at the appointment, when the doctor examines and palpates the formation with their hands. During palpation, the specialist assesses the density of the nodule and its mobility relative to the skin and surrounding tissues. The doctor also clarifies how painless the formation is on pressure and how long ago it appeared. If the nodule lies close to the surface, additional equipment is often not required at all for the initial assessment. When it is located deeply, it is difficult to palpate its borders, so the examination is supplemented with an ultrasound scan of the soft tissues. Ultrasound shows the size, contours and depth, helping to distinguish a lipoma from other similar formations. It is worth recalling in advance when you first noticed the nodule and whether it has changed over time — these details noticeably help the doctor.
What is prescribed and what it shows
What to prepare for the appointment
- Discharge summaries: take previous doctors' reports if the formation has already been examined before — this will help compare the picture.
- Images and reports: bring the results of previous ultrasound scans or tomography so that the doctor can see the dynamics.
- Observations: write down when you first noticed the nodule, whether it changed in size and whether tenderness appeared.
- List of complaints: note what exactly is bothering you now — this will speed up the conversation and remove unnecessary questions.
- Questions for the doctor: formulate in advance what you want to clarify about your formation so that you do not forget anything at the appointment.
Which doctor should I see?
A lipoma is managed by a surgeon, and when there is doubt a dermatovenereologist helps. Below is an outline of what happens at an appointment and what the care consists of.
Which specialist manages this condition
A lipoma is managed by a surgeon, and when the picture is unclear a dermatovenereologist is brought in. The surgeon examines the growth with their hands and assesses its density, mobility and connection to the skin. The dermatovenereologist looks at the skin manifestations and distinguishes a lipoma from other subcutaneous lumps. If there is no specialist nearby, start with a physician at your place of residence. The physician will examine the area and refer you to whoever provides care in your locality. At the first appointment the doctor clarifies when the growth appeared and whether it has changed. Then they decide whether observation or removal is needed, and discuss this with you.
What the treatment consists of
- Observation: suitable when the growth is small, is not growing and does not cause trouble, so the doctor schedules examinations at intervals.
- Surgical removal: performed when indicated or at the patient's request, if the growth is in the way or is changing.
- Liposuction: used in selected cases when it is important to remove the contents through a small access.
- Local anaesthesia: the operation is usually performed under it, and the person remains conscious.
- Excision with the capsule: the growth itself is removed together with its sheath, because this makes recurrence less likely.
- Follow-up examination: after the operation the doctor examines the scar and makes sure that healing is proceeding uneventfully.
What depends on the patient themselves
Regular follow-up is the part of the outcome that rests on the patient themselves. If observation is chosen, come for examination at the appointed times, and not only when complaints appear. Note whether the size, shape or sensitivity of the growth changes, and tell the doctor about it. Photograph the area in good light so that the comparison is objective rather than from memory. After removal, keep the scar clean and dry as the doctor explained, and do not touch it unnecessarily. If there is redness, pain or discharge in the scar area, report it without postponing the visit. Attending the follow-up examination is more important than drawing your own conclusions that everything has healed.
What helps prevent an exacerbation?
There is no specific prevention of lipomas, since the exact causes of their appearance are unknown. However, reasonable habits and attention to your own body help you notice changes in time and not miss the moment when a doctor's examination is needed.
What to change in your habits
Regular self-examination of the skin and subcutaneous tissues helps you notice new growths and changes in existing ones. It is worth examining the whole body, including the back, the back of the head and the areas under the hair, where the eye usually does not reach. It is convenient to do this after a shower, in good light, when the skin is clean and clearly visible. It is useful to pay attention to dense nodules under the skin, their size, mobility and any changes over the recent period. With a hereditary predisposition, such examinations are especially important, because close relatives have already encountered similar growths. If a nodule has started to grow, hurt or change its outline, you should not put off a visit to the doctor. It is convenient to write down the date and what you noticed — this way it is easier to reconstruct the picture at the appointment.
What to keep under control
- The condition of the skin and soft tissues: examine the whole body, including hard-to-reach areas, so as not to miss new nodules under the skin.
- The size of existing growths: compare them with previous notes, because gradual growth is noticeable only with regular comparison.
- Hereditary predisposition: if close relatives have had similar growths, you should be monitored more carefully and more often.
- Any changes in sensations: the appearance of pain, density or mobility of a nodule is a reason to see a doctor without a long wait.
- Timely consultation with a doctor: with new growths or changes in existing ones, an examination helps to sort out the situation in time.
How often to see a doctor
A regular examination by a doctor is needed even when nothing is troubling you and you feel well. Lipomas grow slowly and for a long time give no sign of themselves, so changes are easy to miss without an outside eye. At the appointment, the doctor examines the skin and soft tissues, assesses the size and mobility of the growths, and compares them with previous observations. With a hereditary predisposition, such examinations are carried out more often, because the risk of new nodules appearing is higher. If a growth is enlarging, changing shape or starting to hurt, the visit is not postponed, but made in the near future. Calm observation helps to distinguish harmless changes from those that require attention. Keep the habit of seeing a doctor even when you feel well — this way you stay in control of the situation.
What is worth remembering
A lipoma is a benign growth made of fatty tissue that grows slowly and usually poses no threat to health. The discussion about it should end with a few conclusions that will help you make a calm and balanced decision.
Key conclusions
A lipoma remains a benign growth that may not change in size or shape for years, so sudden anxiety is rarely justified. What should raise concern is rapid growth, hardening, tenderness or a change in the skin over the lump — such changes require a doctor's attention. Trying to remove or squeeze the lump on your own is dangerous: this can introduce infection and damage surrounding tissues. Even a seemingly harmless lipoma needs to be examined by a specialist, because growths that feel similar sometimes have a different nature. You should not put off a visit if the lump interferes with movement, presses on neighbouring structures or simply causes constant discomfort. Being monitored by a doctor allows changes to be noticed in time and a calm approach to be chosen without unnecessary interventions. It is wiser to rely on an examination and a specialist's conclusion rather than on your own guesses that a lump under the skin is safe.
