Loook into photodynamic therapy, which is an effective method for eliminating precancers. I think in New Zealand, it's also used for basal cells. If I get another precancerous spot, I am going to seek it out. I've seen results online and they've looked much more cosmetically pleasing than surgery or creams. From what I could tell, you'll look red and nasty for about a week...but like I said, look into it yourself. If you find out any information, plese post here.
