Moses Maimonides was a prominent physician, scientist, and philosopher, wrote ten medical treatises. His fifth treatise contains surgical aphorisms, some of which pertain to his treatment of cancer. His treatment of large tumors, as he wrote, involves "excis[ing] the tumor and uproots the entire tumor and its surroundings up to the point of healthy tissue, except if the tumor contains large vessels & [or] the tumor happens to be situated in close proximity to any major organ, excision is dangerous."1 2
