After surgery, radiotherapy and chemotherapy, although the pathogenic factors gradually disappear, cancer toxins are still lurking in the body. Traditional Chinese medicine believes that cancer toxin has the characteristics of slow sex, fierce toxicity, easy diffusion, easy consumption of healthy qi and easy blood stasis, and is easy to migrate along meridians and qi and blood. The accumulation of cancer toxin damages the function of viscera for a long time, and produces phlegm for a long time, forming the intersection of phlegm and toxin; Cancer toxin, qi stagnation, blood stasis. Phlegm and blood stasis are intertwined, which leads to depression and corruption for a long time and condensation into poison for a long time. The interaction of phlegm, toxin and blood stasis forms the intersection of phlegm, blood stasis and toxin, which promotes the metastasis of tumor. Generally speaking, the lack of healthy qi and the combination of pathogenic factors are the fundamental factors that lead to or promote tumor metastasis. Therefore, correspondingly, the two therapeutic principles of "strengthening the body resistance and consolidating the foundation" and "eliminating evil and detoxicating" have formed two important magic weapons of anti-tumor metastasis in traditional Chinese medicine.
Traditional Chinese medicine has various methods to treat lung cancer, such as decoction, pill, powder, ointment, etc., as well as external application of traditional Chinese medicine, soaking and washing of traditional Chinese medicine, acupuncture, massage and qigong. The comprehensive application of various therapies can form a joint force to achieve the purpose of preventing and treating cancer. Chinese medicine, in particular, gives full play to the advantages of treating cancer without tumor and preventing degeneration according to the pathogenesis of "deficiency of healthy qi and unhealthy evil" of cancer patients and individualized characteristics. Because the occurrence of tumor is not achieved overnight, people's physical endowment is innate and has long been influenced by acquired growth habits. It takes a relatively long time to improve the unbalanced state of human body through traditional Chinese medicine. For patients with early and radical surgery, if they can keep exercising, adjust their mood and arrange their daily life reasonably, they can consider stopping taking drugs for 2~3 years. Mid-term patients and patients with mild illness, but with more clinical symptoms or weak body, it is best to take the medicine for 3~5 years, and then consider stopping the medicine according to the clinical situation; For lung cancer patients with tumors, long-term drug treatment is needed.
Generally speaking, taking traditional Chinese medicine for a long time after surgery and radiotherapy and chemotherapy, and adopting other comprehensive rehabilitation methods of traditional Chinese medicine, can prevent or delay the metastasis and recurrence of tumors. However, Chinese medicine is not the only treatment. Psychological factors, diet factors, exercise factors and so on will all affect the recovery of the body. While taking medicine, actively adopting comprehensive rehabilitation therapy of traditional Chinese medicine (comprehensive treatment integrating drug conditioning, psychological intervention, physical exercise and nutritional guidance) can better achieve the purpose of preventing tumor recurrence and metastasis and prolonging life.
