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

Pharmacology is benefited by the prepared mind. You need to know what you are looking for.

In the laboratory, we call this the six-degrees-of-separation-from-cancer rule: you can ask any biological question, no matter how seemingly distant-what makes the heart fail, or why worms age, or even how birds learn songs-and you will end up, in fewer than six genetic steps, connecting with a proto-oncogene or tumor suppressor.

Postwar U.S. was the world's leader in science and technology. The investment in science research was staggering.

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