What is lung cancer bone metastasis?

Approximately 50% of lung cancer patients will eventually develop bone metastases in multiple locations.

There are generally no symptoms in the early stages of bone metastasis, and bone isotope scanning can reveal diseased bones. Symptoms of bone metastasis are related to the location and number of tumor metastases. For example, chest pain caused by rib metastasis of lung cancer is often manifested as pain localized in the chest wall with clear tenderness points. Spinal metastasis causes pain in the middle of the back or the lesion site, while bone metastasis of the limbs or trunk causes localized pain in that area. Bone metastasis is not a direct cause of life threats to lung cancer patients, but if the tumor metastasizes to the body's weight-bearing bones such as the cervical, thoracic and lumbar vertebrae, it can cause serious consequences such as paralysis. Therefore, patients with bone metastasis of lung cancer should be treated promptly.
