I can feel a soft lump on my back or neck: is it a lipoma, and should I see a doctor?
When you feel a soft lump on your back or neck, this guide covers the clues that separate a lipoma from an epidermal cyst and the changes that need prompt care. Myongji Best Plastic Surgery Clinic in Myeongji-dong, Busan explains diagnosis, removal and recovery.
Quick answer
A lump that is soft, moves a little when pushed and grows slowly may be a lipoma, but feel alone does not confirm it, so a newly noticed lump should be checked in clinic. If it is hard and does not move, grows, or becomes red, warm or painful, see a doctor without delay. Myongji Best Plastic Surgery Clinic in Myeongji-dong, Gangseo-gu, Busan checks the lump's location, feel, size and inflammation, and when removal is needed it is done under local anesthesia in about 15 minutes per lesion.
Why it matters now
Most lumps under the skin are benign, such as lipomas or epidermal cysts, but other conditions can occasionally feel like a lump. So rather than dismissing a lump because it feels soft, it helps to know first which changes call for a visit.
How does a soft lump differ from a hard lump?
A lipoma forms in the fat layer under the skin, feels soft and squishy, and often moves a little when pushed. An epidermal cyst forms close to the skin surface, feels relatively firm, and may show a tiny hole or dot in the center. These features are only clues, and the type of lump is confirmed in clinic.
| If this is your situation | Option considered | Evidence and limits |
|---|---|---|
| Soft, moves a little when pushed, grows slowly, painless | Option consideredPossible lipoma; confirm the type in clinic | Evidence and limitsThe NHS describes a lipoma as soft and moving slightly when pressed, but feel alone does not confirm it. |
| Round and relatively firm near the skin surface, tiny hole or dot in the center | Option consideredPossible epidermal cyst; do not squeeze, see a doctor | Evidence and limitsThese are epidermal cyst features described by MedlinePlus and the NHS; squeezing can cause or spread inflammation. |
| Redness, warmth, pain, or pus draining | Option consideredPrompt visit to check for inflammation | Evidence and limitsThe NHS advises an urgent appointment for a sore or red lump. When inflammation is severe, the removal plan may change. |
| Hard and does not move, or getting bigger | Option consideredSee a doctor without delay; ultrasound or biopsy if needed | Evidence and limitsThe NHS lists a hard lump that does not move, or one that grows, as a reason to see a doctor. |
| Confirmed benign in clinic, no discomfort | Option consideredMonitor, or remove if you wish | Evidence and limitsIt does not have to be removed if it causes no trouble, but have it checked again if it grows or becomes inflamed. |
Which changes mean I should see a doctor?
It is best to have a newly noticed lump identified, and especially to see a doctor if it keeps growing or comes with pain, redness or warmth. A lump that feels hard or fixed, or one whose location gets in the way of daily life, also needs to be checked.
Change in size
The lump keeps getting bigger, or one is felt again where a lump was removed
Signs of inflammation
Pain, redness or warmth appears, or pus drains
Feel
It feels hard, barely moves, or seems fixed in place
Everyday discomfort
It gets in the way of daily life, such as rubbing on clothes or a bag strap or catching when you brush your hair
How does a clinic confirm whether it is a lipoma?
An examination checks the lump's location, depth, feel, size and any inflammation, and a lipoma is usually diagnosed from the history and examination. An atypical or fast-growing lump is distinguished from other conditions with tests such as ultrasound or a biopsy, and a removed lump is confirmed by pathology when needed.
Examination
Check the lump's location, depth, firmness, mobility, and accompanying symptoms.
Imaging and biopsy
For an atypical or fast-growing lump, ultrasound or a biopsy is considered.
Check after removal
When needed, the removed tissue is sent for pathology to confirm it is a lipoma.
How does Myongji Best Plastic Surgery Clinic remove a lump, and how is the cost set?

The published non-covered fee list does not show a single price for epidermal cyst or lipoma removal (checked October 23, 2026). The total cost is confirmed after the consultation based on size, area and number, and whether anesthesia, pathology and follow-up visits are included; non-covered fees may change.

Rahmani et al., 2017 (systematic review, 6 studies)
Pooling studies of ultrasound diagnosis of soft-tissue lipomas, sensitivity was 86.87% and specificity 95.95%.
Wagner et al., 2013 (62 patients, 72 lumps)
Of 72 superficial lumps confirmed by surgery, 39 were lipomas, and the radiologists' ultrasound readings diagnosed lipoma with 96% sensitivity, 97% specificity and 96% accuracy. One of the 72 was malignant.
Points to note when reading the figures
These studies measured the accuracy of ultrasound readings, not of judging by touch alone. They include a small single-center study.
