Bone metastasis is the advanced stage of cancer, a period when patients suffer much pain, are tricky to treat and face the risk of death. Therefore, after clinical exploration, we found that bone metastasis can be prevented. As long as bone metastasis has not yet appeared after having a tumor (cancer), regardless of whether surgery or chemotherapy, bone metastasis prevention treatment should also be carried out to prevent the occurrence of bone metastasis, which can only be prevented by Chinese medicine. We have made many cancer patients free of bone metastasis in the past two years according to this method, and here we would like to inform that Once cancer occurs, it faces the danger of bone metastasis. Only by immediately starting the TCM treatment to prevent bone metastasis can we eliminate the danger of bone metastasis, especially lung cancer, breast cancer, nasopharyngeal cancer, intestinal cancer, prostate cancer, ovarian cancer, uterine cancer, etc. are all cancers that are prone to bone metastasis. We have treated many patients with bone metastases. Through the focused treatment of Chinese medicine, we have strengthened the bones of patients and relieved and alleviated their pain and condition, that is, the destruction of bone metastases has caused fractures, and the treatment of Chinese medicine can also alleviate the development of the disease and reduce the pain. Many patients do not understand the role of TCM, ignore the efficacy of TCM and give up the treatment of TCM. Some blindly believe in the propaganda of the so-called ancestral TCM doctors on the street, which wastes the time of timely treatment and aggravates the disease. In fact, the main treatment of tumor is to prevent recurrence, prevent metastasis and treat the primary focus, only when these three aspects are taken care of, the tumor is controlled and the patient is safe.
