Lipomas keep coming back after removal surgery. Any suggestions?

It is very unlikely that your lipomas are related to your disc surgery.

In rare circumstances, fat can herniate through the thick tendon-like material ("fascia") and appear as a benign tumor (limp.)

Lipomas related to the spinal cord are also rare, and are more related to malformations of spinal cord that would be detected in childhood. 

What you are describing is much more likely actual lipomas. Lipomas are common benign soft-tissue neoplasms. They consist of mature fat cells enclosed by thin fibrous capsules. Lipomas can occur on any part of the body and usually develop superficially in the subcutaneous tissue.

Lipomas present as soft, painless subcutaneous nodules ranging in size from 1 to >10 cm. They occur most frequently on the trunk and upper extremities. Frequently, patients may have more than one lipoma, and occasionally they may have a genetic condition (familial multiple lipomatosis) characterized by the development of multiple lipomas in several family members.

The diagnosis of lipoma is usually made clinically. If a suspected lipoma causes symptoms (pain or restriction of movement), is rapidly enlarging, or is firm rather than soft, a biopsy is indicated.

The treatment of lipomas, if needed because of pain, cosmesis, or concerns over diagnosis, is surgical removal of the fat cells and fibrous capsule. Recurrence of an excised lipoma--if all of it is removed-- is not common.

1. ask if a biopsy was done, to ensure this is a lipoma

2. if it is truly bothersome to you, removal may be possible if the entire capsule is excised

3. As long as your lipomas are not cancerous, the only reason to pursue removing them is comfort and cosmesis. 

Seek a second opinion, and ask for your biopsy results. 

Thank you for sharing your question and I am sorry to hear of your recurrent lipomas.  As recurrence is quite rare with complete lipoma removal I would recommend an ultrasound of the area to identify any residual lipomas that may simply have not been seen on removal of the first three lipomas.  Assuming there are no discrete fat tumors seen, you should not have the problem of a lipoma growing again.  Best wishes.
