A lipoma is a benign growth of fatty tissue. Having one does not automatically mean you need an operation. Once your doctor has established the diagnosis, the decision usually centres on whether the lump is causing problems and what removal would involve.[1][2]
On this page
This article is for someone whose lump has already been assessed as a lipoma. Use the appointment to discuss your particular reason for considering removal.
When can a lipoma be left alone?
A lipoma often needs no treatment. If it is comfortable and does not bother you, observation may be reasonable. A diagnosis does not have to be followed immediately by surgery.[1]
Symptoms or interference
Pain or interference with function can justify discussing removal. For a lipoma within muscle, treatment decisions take its location, size and symptoms into account.[3]
If the lump grows or becomes troublesome, arrange another assessment. Larger, deeper or unusual lumps sometimes need imaging or tissue testing. A previous label of “lipoma” should not replace a fresh discussion when the situation has changed.[1]
Why size and depth change the discussion
Some lipomas lie within muscle rather than just beneath the skin. With these deeper lesions, the surgeon considers nearby structures and how removal might affect function. A small intramuscular lipoma without functional problems may be observed; a symptomatic one may be considered for surgery. The operation needs to suit the actual lesion.[3]
Be specific about the change you hope for. A lump that catches under a waistband presents a different concern from one whose appearance bothers you. Describe the difficulty in your own words, including what you would want to be easier after treatment.
What happens during lipoma removal?
For a superficial lump, removal generally involves a cut over the area, taking out the lump and closing the wound. The stitches may dissolve or may need removal. The proposed incision and wound closure are part of planning the operation.[4]
Many superficial lumps are removed under local anaesthesia. Larger lumps or multiple removals may require general anaesthesia. Your surgeon should explain the proposed approach and the arrangements you will need around it, including getting home after the procedure.[4]
The scar and other risks worth discussing
Excision leaves a scar. Its appearance depends partly on the site, the size of the procedure and individual healing. Discuss whether the likely scar would bother you more than the lump, particularly if appearance is your main reason for removal.[5]
For minor superficial excisions, recognised risks include bleeding, infection, delayed wound healing and altered sensation around the wound. Your surgeon should explain which risks matter for your operation. A general leaflet about skin surgery cannot estimate the risks of removing a deep lipoma near important structures.[5][3]
Planning recovery and the pathology result
Recovery advice depends on the size and site of the operation. Some people need physiotherapy after removal of a lipomatous tumour. Your plan should cover work, lifting, exercise and activities that use the operated area.[2]
Some soreness, bruising or swelling can occur afterwards. Follow your own discharge instructions for the dressing, washing and pain relief. The instructions should also say whether stitches need removing and who will review the wound.[6]
Your team should explain whether the removed tissue will be sent for laboratory examination, how you will receive the result and whom to contact if it has not arrived.[6]
When to contact the team after surgery
Seek medical advice if the wound becomes hot and increasingly inflamed, develops an offensive discharge, or you feel feverish. Severe pain or bleeding that does not stop needs urgent assessment. Keep the contact instructions provided by your surgical team readily available.[6]
If a lump appears again at the operation site, arrange a review. Familiarity with the area can help you notice a change, but does not establish what a new lump is.[2]
Before you decide
- What problem is removal intended to solve?
- Is observation a reasonable choice for me?
- What scar and restrictions should I expect?
- How will I receive the tissue result and obtain help afterwards?
