Can you tell me about tumor removal?

Wide margins.: We are beginning to find that most if not all malignant tumors arise in a field and that many areas of normal cells around the tumor are in actuality malignant expressing tumor protein and express genetic alterations of malignancy. To cure a tumor, wide excision hoping to excise all potentially premalignant cells are required. This probably converts to a margin of 2-5 cm

Adequate resection: Tumors both benign and malignant must be removed with adequate margins so that tumor cells are not left behind. In addition there shouldn't be damage to surrounding organs. The rule is that simple and radical surgery are not important. What is needed is adequate surgery to remove the tumor to prevent recurrence.
