Growing Lipoma On Back Near The Spine. Diagnosed Not Cancerous. Chances Of Nerve Damage?

I was diagnosed with a lipoma on my back. It is about an inch in diameter proximal to my vertebral column. I was told these are not cancerous, but I would like to have it removed because it appears to be growing instead of decreasing. Since it rests so near to my spine, what are the chances of nerve damage. Also, is it likely to return? And oh, I almost forget no insurance, so I'll be paying out of pocket. How much, please?
