Hello! Lipomas are best served being surgically excised. This will significantly reduce the possibility that it will return. Depending on the size and location, they may be removed under simple local anesthesia and possibly in the office. I would discuss the options with a plastic surgeon who can examine you and discuss the options and procedure. Almost routinely they are outpatient procedures. Depending on the location and size, your surgeon may put you on some restrictions, but most likely you will be back to doing most things after a few days - discuss this with your surgeon. There are other things that this soft tissue mass may be and it is wisest to have it examined prior to consideration for any surgical excision.Liposuction, although an option, is not a great modality due to the recurrence rate as well as not knowing what this mass actually is. Steroids is not an honored treatment for lipomas. Cost will vary upon the examination of the mass, location and complexity of the mass, and will increase if done at a surgery center and use of anesthesia. Thank you for your question. Hope that his helps!
