Possible Cyst on scrotum? Cost to remove? (Photo)

One year ago, I removed what I thought to be an ingrown hair from the center of this growth. The lighter circular area on the bottom-right corner of the growth is the exact point where the hair was removed. The growth seems to only be attached here because I can it move the freely, under my skin, around this point. What treatment would be more cost effective; removal by surgery or medication? How much would either cost?
