Dr Azra Raza: We can do better with cancer treatment

Cancer treatment is an embarrassment, based on a slash, burn and poison approach that's failed patients for the last 50 years. That's the brutal assessment made by oncologist Dr Azra Raza.

She says too much money is being poured into expensive and ineffective treatment when it should be spent on prevention and early detection. She shares her journey as a doctor and wife of a cancer patient and how we can do better in her book, The First Cell: And The Human Costs of Pursuing Cancer to The Last.
