Stanton's early work at the National Cancer Institute was on chemically-induced carcinogenesis, after which he shifted to viral oncology. His last years were spent working on fiber carcinogenesis, and in particular on the carcinogenic effect of asbestos.

Samuel S. Epstein devoted his career to the study and identification of carcinogenic mechanisms in industrial pollutants, pesticides, cosmetics, food, as well as the entire range of environmental contaminants. He used his knowledge and experience to warn the public of risk, to advocate for regulation, to encourage cancer prevention measures, and to serve as an expert witness on the public's behalf on issues of toxic contamination and disease.
