Abstract
Tomizo Yoshida preached the individuality and diversity of cancer. He said that it is important to find out the common or most fundamental traits of cancer cells. Yoshida boldly stated that we humans play up the future-a sign of our inner desire to avoid reality. Apart from being a cancer pathologist, Tomizo Yoshida was also a thinker who eloquently used analogies of cancer to explain his outlook on life.
In a world complex with many incomprehensible factors, confused by issues, my wish is that this teaching-the Philosophy of Cancer-sheds light on the path to the future.
