Berger observes the everyday work of the physician, surgeon, radiotherapist, clinical lab workers, virologists and others, with the usual attention to mechanics and ""instrument panel"" photos but with a little more background information on what the work is all about than in other of his Scientists at Work series (though there is nothing like the briefing on basics provided in the Silversteins' Cancer). The pitch is optimistic though not breathless (""more and more cancer patients are surviving major operations"" and ""immunology is a bright new hope""). Routine.
