Surgery, radiotherapy and chemotherapy are the main conventional treatments for lung cancer. For middle and late stage lung cancer, surgery has a low possibility of cure, and combined with radiotherapy and chemotherapy, it is still prone to recurrence and metastasis, so the prognosis is also slightly worse than other malignant tumors. Combining with TCM treatment and tapping the potential and advantages of TCM treatment for lung cancer can bring survival advantages and improve the quality of life for lung cancer patients. If lung cancer patients can timely cooperate with TCM treatment after surgery, they can support their righteousness, improve their diet and sleep conditions, enhance their physical fitness, and accelerate their timely return of vital energy after surgical trauma. In the tumor-free stage after surgery, adjusting the patient’s body type, clearing the remaining cancer toxins in the body and strengthening the body immunity can play an extremely important role in reducing the recurrence and metastasis of lung cancer. If Chinese medicine treatment is combined with lung cancer chemotherapy or after chemotherapy, such as strengthening the spleen and stomach, benefiting qi and blood, tonifying liver and kidney, softening and removing stasis, it can better alleviate chemotherapy reactions, help chemotherapy proceed smoothly and improve the efficacy of chemotherapy; if Chinese medicine treatment is combined with tonifying qi and blood during and after lung cancer radiotherapy, it has better effects on increasing the number of white blood cells and enhancing immune function, thus ensuring radiotherapy This can ensure the smooth implementation of radiotherapy. The combination of TCM can reduce the toxic side effects of Western medicine and significantly improve the survival period and quality of life of patients. For patients with advanced lung cancer who have lost the opportunity of surgery and radiotherapy, when chemotherapy and biologic targeted therapy are ineffective, TCM is the main force of treatment. Its effects of enhancing immunity, anti-cancer and cancer suppression, inducing apoptosis of cancer cells, blocking tumor angiogenesis, etc. are far beyond the symptomatic treatment of Western medicine, and survival with tumor under TCM treatment is also the best strategy.
