Cancer development is associated with a “cancer characters”. “Cancer characters” refer to the characters of being eccentric, depressed, and lowering oneself. Forty percent of cancer patients are attributed to these characters.
A research institute has conducted follow up for 20 years and categorized mortality according to the human characters. As a result, researchers reported that people who oppress themselves and deny their actions are easily prone to cancer, and incidence of cancer of people who have introvert character is about 15 times as high as those who are cheerful. The reason is that the long-term depression of their emotions leads to a loss of immune function and a loss of resistance to cancer.
