> Review articles are good, but I still recommend starting with textbooks before moving on to reviews.
We are agreed on that. I shouldn't have said "out of date", which suggests what is in those books is invalid. What I should have said is "they don't really cover topics that are new or controversial and mostly only cover fundamentals".
In reality as you know each new edition of those books is 95% or more identical to the previous edition.
The only downside to this approach is that if people are interested in a particular topic like cell senescence, it's a bit harsh to say "go read these 5 textbooks that may have 2 pages on the subject before you even start looking into the topic you're interested in". And the Biology of Cancer? I'm published on several cell senescence papers and don't know jack about cancer. I own the book and skimmed it though. I think Hallmarks of Cancer review is a much better introduction than this tome. The other two are good fundamentals books though. For aging I recommend Handbook of the Biology of Aging.
FWIW, I do not know a single PhD student that read those books cover-to-cover. In most of my grad school classes you weren't even required to buy the textbook and they were barely used. Actually in grad school I never bought a single textbook for classes, although I did get some for personal use.
