Wanna hear a fun fact? One of the original papers on p53 acting as a proto-oncogene got rejected from Nature because the author was "trying to jump on the bandwagon of tumor suppressors; it's fashionable, but it's wrong. It's very clear that p53 is an oncogene." As a side note, I would recommend this book over all other cancer books I've read. Emperor of All Maladies is interesting from a treatment perspective, but p53 is the most up to date and well-written book I've read from the perspective of the biology of cancer and the stories of the researchers who found the discoveries (kleinbl00).
Note that this book supplants Natural Obsessions with its similar focus but also the inherently better attribute of not being written in the 80s. It does feature less of Weinberg (one of the gods of cancer biology) though.
