A good sound, quickie cancer education for the less well informed (and most people are less well informed about cancer than they think). Tells you what a cancer is and how it works, runs down the commonest types, briefly explains staging and treatment, gives some interesting statistics, diplomatically touches upon alternative and psychological curing. The publication date will tell you that the treatment part and some of the recommended medical centers are probably out of date. Will appeal to: people just coming to grips with a diagnosis.
