At present, there is no direct evidence that there is a relationship between strenuous exercise and bone cancer. Bone cancer is also known as malignant tumor disease of bone. At present, the cause of bone cancer is not very clear, but it is considered to be related to bone injury and infection, genetic factors, ionizing radiation, environmental factors and so on. 1. Bone injury and infection: existing researches believe that bone injury or chronic infection may be related to bone cancer. 2. Hereditary factors: people with family history of bone cancer are more likely to develop bone cancer than normal people, and certain gene or chromosome abnormalities can often be detected in bone cancer tissues. 3. Ionizing radiation, such as X-rays, is also related to the occurrence of bone cancer. 4. Environmental factors: frequent exposure to chemical carcinogens will have a certain impact on the occurrence of bone cancer. From the existing research on bone cancer, there is no evidence that strenuous exercise can induce bone cancer. If bone cancer is diagnosed, standardized treatment is recommended.
