I believe the biggest breakthroughs on cancer could come from brilliant researchers based in India.

A positive attitude does not cure cancer, any more than a negative one causes it.

Down to their innate molecular core, cancer cells are hyperactive, survival-endowed, scrappy, fecund, inventive copies of ourselves.

History repeats, but science reverberates.

Cancer has enormous diversity and behaves differently: it's highly mutable, the evolutionary principles are very complicated and often its capacity to be constantly mystifying comes as a big challenge.

If there's a seminal discovery in oncology in the last 20 years, it's that idea that cancer genes are often mutated versions of normal genes.

There is a duality in recognising what an incredible disease it is - in terms of its origin, that it emerges out of a normal cell. It's a reminder of what a wonderful thing a normal cell is. In a very cold, scientific sense, I think a cancer cell is a kind of biological marvel.
