From painstaking ten-minute to half-hour microscopic examinations of each of 19,797 exquisitely thin slivers of tissue from human lungs, medical researchers reported last week that they had found the strongest anatomical evidence that heavy cigarette smoking is a potent cause of lung cancer. At the A.M.A.'s Dallas meeting, Dr. Oscar Auerbach of East Orange, N.J. told how he and a distinguished colleague, Dr. Arthur Purdy Sout (retired professor of pathology at Columbia Uni versity's College of Physicians and Surgeons), had examined the magnified tissue slides, cell by cell. Working with them were...

It was just as well: testololactone has proved to have all the virilizing properties of testosterone. But the delta1 variant, tested so far in 24 patients, proved in seven cases to be as potent as testosterone in suppressing cancer growth, and with no virilizing effects...
