What should Bill Do?

Three treatments that Bill could choose as options are surgery, chemotherapy, and simple excision. Each of these would be a good option for him, but in my opinion I think that Bill should get the spot surgically removed. Knowing this kind of cancer, it will eventually spred to other organs or tissues and could get more severe than it already is. The sooner he makes his decision, the better off he will be before more problems come of the cancerous cells. Going through surgery to remove the whole spot would most likely be the most successful.
