Do the attending physicians have an obligation to work with the father in order to help remove the evil spell?

A ten-year-old boy from a rural Mexican family was being treated for cancer of his distal femur. According to the boy’s father, his son’s cancer began when the boy was kicked by a child from a neighboring family with whom the father had been feuding. The father believed that his neighbors had cast an evil spell, causing a snake to invade his son, and thus the child had developed an illness as a result of the kick. Because of the father’s beliefs that there was a supernatural cause for his son’s illness, he also believed that the evil spell would have to be removed before the boy could be cured.
