Ralph W. Moss was Assistant Director of Public Affairs at Memorial Sloan-Kettering Cancer Center in New York City when he unveiled a cover-up of positive tests with America's most controversial anticancer agent, laetrile. He was ordered by MSKCC officials to falsify reports. He refused. Instead, he organized an underground employee group called Second Opinion to oppose this cover-up. Moss is the author of ten books on cancer. This is his most dramatic work: a first-person account of those shocking events.
