One Renegade Cell is a classic by now in terms of pop science books which explain cancer for an interested but non-specialist audience. It’s a little out of date, and some of the hopes Weinberg talks about in terms of treatments to come haven’t come to pass at all. But the basics are still true, and you can get a good basic understanding of how cancer works by reading it. It’s clear and accessible, and I didn’t find it prone to fear-mongoring either — sometimes when someone is writing about cancer, it seems like they can’t help but try to scare the reader silly.
One Renegade Cell doesn’t try to mystify cancer or play up its impact; the impact of cancer pretty much speaks for itself. It’s a solid read, even though it’s out of date now.
