For those who haven't seen it, the Public Broadcasting System in the U.S. made a fine video of Siddhartha's very fine book, _The Emperor of All Maladies_. I read the book and watched the video and thought both were very worthwhile. Mukherjee, himself an oncologist, relates the history of cancer treatment, including the first surgeries, the first attempts to explain the cause of the disease, the use of radiation, chemotherapy, "targeted therapy" and so on.
Neither the book nor the movie is too technical for a popular audience to understand. I recommend it to everyone, but I particularly recommend it for those who might be attracted to the view that medical oncology today is just a collection of money making scams.
Here is a link to Episode 1 on YouTube. There are three episodes in total.
I found the book in my local public library and I expect that most public libraries will have copies.
