How mental states can influence physical health.

I would like to discuss how mental states can influence physical health. Give an example and I explain it. Afterward, I tell what the most important thing is.
In case of person who has the terminal cancer, a doctor told him about limit of his life. The doctor said that he wouldn’t be able to live enough time any more. Also the doctor said that his life has limit by six months. However, he had never lost his gats. Then, he could live until three years. Actually it has some cases that people who got terminal cancer overcame their disease because of their gats.
Finally, the most important thing is always having positive thinking, which will help better our life.
