What is the fastest way to get rid of a Cyst that is under the skin in the abdomen?

I have a cyst under the skin above the belly button, I know this as I went to the doctor and he confirmed it was a cyst. He said to leave it but I want to get rid of it for cosmetic reasons. What is the fastest and easiest way to get rid of it. I heard castor oil, tea tree oil and hydrogen peroxide are all good, does anyone have any recommendations? Any help would be much appreciated.
