According to the literature, more than one million new cancer patients are diagnosed each year in the United States, and about 50% of them eventually develop bone metastasis. The sites where bone metastasis occurs are mostly in the mid-axis bone and lower extremity, especially in the hip region. Bone metastases occur most frequently in the spine, followed by the pelvis and the long bones of the lower extremities, and far less frequently in the knee and elbow joints. Bone metastases can be divided into three types: osteolytic, osteogenic, and mixed. Generally speaking, osteolytic metastasis is the main type of metastasis in breast cancer and lung cancer, while osteogenic metastasis is the main type of metastasis in prostate cancer. The main symptom of bone metastasis cancer is persistent pain, which is continuously aggravated and often unbearable for patients. The bone swelling is as hard as a pinprick, and can cause impaired movement, pathological fracture and paraplegia, which seriously affects the quality of life of patients. If you are a patient with frequent back and leg pain, you must raise your vigilance and go to hospital for examination in time when abnormal pain symptoms that cannot be tolerated appear, so as not to delay treatment and cause serious consequences. Clinically, treatment of bone metastatic cancer usually adopts chemotherapy, radiotherapy, bone resorption inhibitors and anesthetic analgesics, which stop the cancer cells from destroying bone on the one hand, and relieve patients’ pain on the other, but the treatment effect is still not satisfactory due to many reasons. Chinese medicine classifies bone metastasis cancer as “bone tumor” and “bone erosion”, and its pathological mechanism is the original deficiency and the symptom is the actual one. For different people and different situations, the treatment of Chinese medicine plays a very big role. During chemotherapy, together with Chinese medicine, it can significantly increase bone density, control bone lesions and improve pain, and play the role of reducing toxicity and increasing effectiveness. We treated 56 cases of postoperative bone metastases from breast cancer and observed the therapeutic effect of taking Chinese herbal medicine compared with those without it. We found that the patients taking Chinese herbal medicine had significantly improved their condition, improved their quality of life, and had significant efficacy in terms of organism immunity, reducing hematological toxicity and increasing white blood cells. Patients with bone pain from breast cancer metastases should pay attention to: 1. Patients with bone metastases from breast cancer should eat kelp, seaweed, seaweed, oyster, asparagus, fresh kiwi and other foods with the function of dissolving phlegm and softening hard knots. 2.When breast cancer bone metastasis patients undergo radiotherapy, it is advisable to eat sweet and cool nourishing products, such as almond cream, loquat, pear, plum, banana, lotus root, carrot, jellyfish, etc. When breast cancer bone metastasis patients undergo chemotherapy, they are prone to gastrointestinal reactions and bone marrow suppression, so they can eat products that harmonize the stomach and lower the rebellion, benefit the qi and nourish the blood, such as fresh ginger juice, sugar cane juice, fresh juice, peel, tomato, japonica rice, ganoderma lucidum, black fungus, sunflower seeds, Liaoning spiny ginseng, etc. 4.Patients with breast cancer bone metastasis should eat less fat, cheese, cream, etc. Avoid eating spicy products, such as chili, pepper, garlic, garlic moss, onion, onion, mustard, leek, and old pumpkin, etc., so as not to help fire and produce phlegm. Do not eat shrimp with seeds; eat less cream of hairy crab; milk, soy milk can be consumed in small amounts, but not recommended for long-term consumption. 5, the intake of fruit, it is recommended that a day a variety, a fruit on, eat too much, may affect fat metabolism. 6, good mood is more important than anything else. 7, now people are not eating too little, but eating too much, rough food is best.
