Not Related to That Depressing Post

I am reading Mukherjee's The Emperor of All Maladies: A Biography of Cancer.  It is clearly written, engaging, and makes only a few assumptions about how strong your vocabulary is; I have only looked up a couple words.

There is a profoundly uplifting narrative of how child leukemia was transformed from a near certain quick death by the discovery of chemotherapy as a consequence of a bomb hitting an American ship carrying mustard gas (which I knew about, but not this level of detail).  

It is also a story of what happens when pride overcomes good science.
