About The Cover

Aided by sophisticated molecular genetic techniques, researchers are assembling an increasingly detailed profile of the molecular changes that characterize human cancer cells. The cover illustration portrays our struggle to understand and apply this information to defeat the disease. The Editorial (995), News stories, and Articles (see the special section beginning on 1035) review current efforts in prevention, diagnosis, and treatment of cancer. [Illustration: Celia Johnson]
