Cancer is both a disease and a disease of the heart. Recent research results on the relationship between psychological factors and cancer in modern society show that various psychological factors have a very important relationship in the occurrence, development and metastasis of cancer. According to Chinese medicine, “worrying about qi”, excessive depression, depression and other adverse psychological factors can lead to qi stagnation, and qi stagnation leads to blood stasis, and phlegm, fire, dampness and toxicity condensation are important causes of tumors and also contribute to tumor development. The treatment method of “dredging liver and relieving depression” in Chinese medicine is based on this theory. Of course, the psychological state of the patient is also a very important factor. A good psychological state has an important significance in cancer treatment that cannot be replaced by scalpel and drugs. We do not think that spirit is everything, but at least in the process of tumor prevention and recovery, it is nothing without spirit. Without the support of spirit and perseverance, even the best medicine will not produce good results. The human body responds to psychological cues consciously or unconsciously, and many psychological effects can have a direct impact on human tissues that we do not feel. The mind can make us stronger or weaker, more uplifted or lost. “When the mind is big, big things become small; when the mind is small, small things become big”. By keeping a good mind, not only will one’s life be happy, but the organism will also respond to these positive psychological cues and become more resistant to disease, thus inhibiting the growth of cancer cells. Buddha said: If you want to live a casual life, you can only live an ordinary life; if you want to live a brilliant life, you can only live a painful life; if you want to live a long life, you can only live a simple life. Cancer patients should learn to let go of their baggage and let go of their mood, which is good for their physical and mental health. The road to beat cancer is a long one, but after all, we have had such a long journey. There is no doubt that the day to finally subdue cancer is getting closer and closer. In the battle against cancer, every patient, family and doctor is a warrior. Although countless lives have fallen, human beings are still standing up, and we continue to fight cancer with our strong will, with reason, passion, wisdom and even life. Zhuangzi said thousands of years ago, “Be careful to guard your body, and things will be strong”. Everyone must guard their body carefully, persevere and wait, because we firmly believe that mankind will overcome cancer.
