Early stage of lung cancer usually has no obvious symptoms and is unlikely to have back pain. If pain occurs, it is not necessarily lung cancer, so you cannot judge it only by back pain. When the tumor of lung cancer invades the ribs, spine and tissues outside the chest wall, it may cause involving pain in the back, and the pain is usually persistent and obvious, and not related to breathing and coughing. However, patients with early stage of lung cancer usually do not have pain, and only have symptoms such as coughing and wheezing, or even may not have symptoms. Persistent and obvious back pain may be caused by muscle strain, cold, cervical spondylosis, etc. Therefore, it is not possible to judge whether it is lung cancer by the nature of back pain. Therefore, it is not possible to tell whether it is lung cancer by the nature of the back pain. It is recommended to have relevant examinations in the hospital, such as CT of the lungs. If lung cancer is diagnosed, early treatment should be carried out to control the development of the disease to the greatest extent.
