Colon cancer generally refers to a malignant tumor that grows on the colon and typically appears in middle-aged populations. If colon cancer is not treated promptly, it can easily lead to bone metastasis. The bone metastasis of colon cancer is similar to other tumor metastases. The symptoms such as chest pain or tenderness upon pressing could be caused by bone metastasis from lung cancer. In the early stages of colon cancer, there are generally no symptoms of bone metastasis. However, once the tumor metastasizes to weight-bearing bones, thoracic vertebrae, cervical vertebrae, or lumbar vertebrae, it can result in paralysis. Patients must seek timely medical examination and treatment at a hospital to prevent the cancer cells from metastasizing.
