In the process of tumor treatment, the use of medicine is like the use of soldiers, which requires a phased strategy according to the patient’s condition and the changing status of the power of both evil and positive. (1) When the evil energy is strong at the time of diagnosis, but the positive energy still exists, various means of Chinese and Western medicine (surgery, radiotherapy, traditional Chinese medicine) should be used to combat and destroy the tumor as much as possible (attacking the evil energy), and attention should be paid to protecting the positive energy and using traditional Chinese medicine to reduce toxicity and increase effectiveness. (3) After the reconstruction of immune function and bone marrow hematopoietic function, if necessary, the treatment can be transferred to the third stage, which is mainly to fight against tumor, to consolidate the treatment and remove the potential residual cancer cells as much as possible (4) Later, the treatment can be transferred to a long period of positive and anti-cancer treatment (mainly to support positive and suppress cancer) to prevent tumor recurrence and metastasis. This model is one of the experiences and principles of clinical treatment, as it has been proved to prolong the survival period, improve the quality of survival and increase the cure rate of cancer to a certain extent.
