My grandparents’ disapproval was actually a more traditionally Jewish response than many other Jewish parents of that generation seemed to have, at least in respect to the Jewish law banning self-mutilation. But most Jewish theologians actually make allowances for plastic surgery, depending on the situation.
“From a Jewish perspective, you’re not allowed to intentionally injure your body, because your body belongs to God and you have it on trust during your life,” explained Rabbi Elliot Dorff, author of “Matters of Life and Death: A Jewish Approach to Modern Medical Ethics” (JPS, 2004). However, he added, “we do have the permission and even the mandate to heal. The Jewish tradition understood mental illness to be a serious matter.”
In other words, therapeutic plastic surgery, to cure burn victims, for example, is allowed by Jewish law. So is the removal of a big mole, argues Dorff. “Even some things that are not physically problematic, but are nevertheless very distasteful, I think that would be very reasonable,” he said, noting the immediate gray area that arises. “You clearly are allowed to do other things to look better, like dress better or pierce your ears, to feel good about yourself. The question is whether you are allowed to undergo surgery to look better — the degree to which surgery is the proper response to the feeling,” Dorff said.
