CANCER CAUSE IN TOBACCO — “You might as well ask a person if he believes the earth is round as to ask him if he is one of those who believes cigarettes cause cancer,” Dr. Charles B. Huggins, director of the Ben May Laboratory for Cancer Research, University of Chicago, told SCIENCE SERVICE.... Sixty known cancer-causing compounds have been tested.... Two components of deoxyribonucleic acid — guanine and cytosine — were made into a molecular model and a plastic frame was constructed to surround it. In this frame, Dr. Huggins showed, in slides, how all known cancer-causing aromatic hydrocarbons fit neatly. Also similar atomic models of the steroids testosterone (male hormone) or progesterone or estradiol (female hormones) fit.
