[单项选择]Occasional self-medication has always been part of normal living. The making and selling of drugs have a long history and are closely linked, like medical practice itself, with the belief in magic.

The ancient Egyptians knew about many tumors that had a bad outcome, and the Greeks made a distinction between benign tumors (oncos) and malignant ones (carcinos). In the second century A.
