A lot of information is packed into about 200 pages. Covers such topics as oncogenes, tumor supressor genes, growth factors, transmembrane receptors, signaling pathways, etc. Gives some historic background and describes some of the methods of research used. Gives an over-all picture of the multi-step model of cancer's origins. Does not cover medical/clinical aspects of cancer.
You may want to read this book because you have cancer and want to study a little about it. A good choice. For a good, shorter, simpler book, read Robert Weinburg's other book, "One Renegade Cell".
