Recently I had a growth on the side of my head that got bigger quickly. I went to a dermatologist to get it removed. He said it was nothing to be concerned about. Seems this type is part of getting along in years. He removed it with no problem.
Later I had the same type show up on the back of my hand. I simply massaged castor oil on it daily. Kept it from getting dry and after 3 weeks or so it flaked off.
Picture below shows a growth similar to what I had.
