In 1982 Harvard Medical School Geneticists Philip Leder and Timothy Stewart developed a technique for producing mice that were highly susceptible to breast cancer; they modified a naturally occurring gene to make the mice more sensitive to cancer-causing agents, then injected the altered DNA into the embryos. By subjecting the adult mice to carcinogens and studying the malignancies that develop, scientists will have a unique opportunity to analyze the complex interplay between environmental and hereditary origins of cancer -- and possibly even produce more sensitive...
Tragedies have certainly occurred. Among the most notorious have been cases of women who, despite negative Pap smears, turned out to have cervical cancer. ( Some have died; others have been forced to have hysterectomies. Had the disease been caught early, minor surgery could have sufficed.
