Suggest Treatment For Lipoma In The Ankle

was told that lipoma on my ankle is the result of my body trying to heal the torn tendon; lipoma occured 12 hrs after tendon tear.
was told that once tendon is repaired, the lipoma *might* shrink on it's own, but it might not too.
Why would the body cause a lipoma next to a tear in tendon? Since the lipoma is a fatty tissue, what would it have to do with the torn tendon?
Thank YOU!
