Bone cancer is a general term for malignant bone tumors, which commonly include osteosarcoma, chondrosarcoma, fibrosarcoma, etc. It refers to tumors involving bones, which can occur in bone cells, hematopoietic components of bones, cartilage and fibrous or synovial components, and is a typical systemic malignant disease. Bone cancer is very harmful, and it is necessary to pay attention to treatment and prevent recurrence Bone cancer is very harmful. First of all, after the disease, patients’ bone health will be severely damaged, resulting in their inability to perform normal daily activities. Early symptoms of bone cancer can be divided into benign and malignant, while benign bone tumor is relatively common and malignant bone cancer is less common. Secondly, after the onset of the disease, patients will have difficulty in sleeping and eating due to bone pain, and their appetite will keep decreasing, their physical condition will become weaker, and they may even have fever and vomiting, which are also the symptoms of bone cancer. Finally, the density of bone is not uniform. There is irregular destruction, blurred surface and unclear boundary, and the lesion mostly starts from epiphysis. If these conditions appear, it is necessary to go to hospital for treatment as soon as possible. If the disease develops to metastasis at a later stage, the condition will not only be badly controlled, but also may lose precious life. Bone pain is one of the first symptoms of patients, and the damage caused is self-evident. It can occur before the appearance of tumor, initially as intermittent pain, gradually turning into continuous severe pain, especially at night. Although the disease is very harmful, bone cancer is not an incurable disease, if we can actively carry out treatment, we can effectively control the disease. Therefore, bone cancer patients must pay attention to treatment and regular examination. Bone cancer patients usually do not listen to doctors’ advice and follow up and review regularly, and regret only when bone cancer recurs again. Generally speaking, the body immunity of bone cancer patients decreases, so it leads to the recurrence of bone cancer patients. Many bone cancer patients already have a reduced immunity before surgery, plus the blow to body resistance from surgical trauma and anesthesia, which leads to even lower immunity. If they do not pay attention to strengthen nutrition and restore immunity in time after surgery, it provides opportunities for tumor recurrence or metastasis. These reasons can lead to bone cancer recurrence Most bone cancers can obtain more satisfactory curative effect through active treatment, and its harm to human body is more from its recurrence and metastasis, so we should pay attention to prevention. The main reasons for recurrence of bone cancer after surgery are as follows: 1. Irregular life Regular life is good for health. Some bone cancer patients don’t pay attention to the daily routine after recovery, often overeating, reversing day and night, drinking and smoking excessively, which leads to the decrease of body resistance and gives an opportunity for bone cancer recurrence, which is one of the most common reasons for bone cancer recurrence. 2.Low immunity of the body Many bone cancer patients’ bodies are especially weak under the effect of tumor, which, together with the absence of very good treatment methods, leads to low immunity. If they do not pay attention to strengthening nutrition and restoring immunity in time, it will provide opportunities for tumor recurrence or metastasis. 3.Not to pay attention to consolidation treatment and follow-up medical examination After receiving treatment, some bone cancer patients think that everything is fine, so they relax the follow-up consolidation treatment, no longer take medicine on time, and do not follow the doctor’s advice to have regular follow-up medical examination, and regret only when bone cancer recurs again, which is the most important factor among the causes of bone cancer recurrence. 4. Poor mood Frequent anger, depression and irritability can easily trigger the occurrence of diseases. For bone cancer patients, poor mood and excessive pressure are also prone to recurrence. Through the understanding of the above knowledge, it also gives a reminder to many patients. The temporary treatment of bone cancer does not mean that it will never recur. Therefore, even after cure, we should do preventive work to avoid the recurrence of bone cancer. In addition, we should get more sunlight, which is not only good for our body, but also has a certain effect on the prevention of bone cancer.
