“Cancer” is a systemic disease that manifests itself locally as a tumor and is a chronic disease that can be cured. Cancer treatment requires comprehensive treatment and adherence to traditional Chinese medicine over a long period of time. With the continuous development of medical science and the scientific and comprehensive application of various effective cancer treatment methods and means, the effect of cancer treatment has been significantly improved in recent years. Anti-Cancer Problems – Recurrence and Metastasis However, the problems of cancer recurrence and metastasis have not yet been solved. Anti-recurrence and anti-metastasis are two important issues, which are long-term treatment processes. In this long-term process, effective comprehensive treatment in the early stage is the most basic and decisive foundation; the patient’s firm confidence, comfortable mood, moderate exercise, work and proper diet are extremely important. In addition, traditional Chinese medicine plays a very important role. The key of anti-recurrence and anti-metastasis is to improve one’s own immunity At present, effective methods and means of treating cancer (including surgical resection, radiation therapy, chemotherapy and other methods) cannot kill 100% of the remaining cancer cells in the body. Theoretically, the suppression of cancer cells remaining in the body can only rely on the patient’s own immune function. A strong body with strong immune function can effectively inhibit the remaining cancer cells from attacking, recurring or metastasizing to other parts of the body. Although there are a small number of residual cancer cells in the body, the body is in a healthy state without cancer, and the relevant cancer marker indicators (e.g. CEA, CA199, CA153, CA125, AFP, PSA, etc.) are all within the normal range. They can live, work and exercise like other healthy people. Once the body’s immune function declines and the ability to resist diseases is weakened, the remaining cancer cells in the body cannot be effectively suppressed, resulting in the uncontrolled mass replication of these small number of remaining cancer cells, and “recurrence” or “metastasis” occurs. Through long-term observation and a large number of cases, it is fully proved that the recurrence rate and metastasis rate of patients who insist on taking traditional Chinese medicine for a long period of time are far lower than those who do not take traditional Chinese medicine, and the five-year or eight-year survival period of the former is far higher than that of the latter. Even for patients with recurrence or metastasis, or for patients in the middle and late stages who have not undergone comprehensive treatment and who simply take Chinese medicine, their quality of life, survival period and clinical symptoms are better than those who have not taken Chinese medicine.
