Chest and back pain is not an early symptom of lung cancer. In the early stage of lung cancer, there may not be any symptom, or there may only be many atypical symptoms, such as weight loss, cough, blood in sputum, shortness of breath, fatigue and so on, which patients usually do not pay attention to, or they may only think that it is a small disease such as cold or pneumonia, and they will not go for checkups, which will cause delay in the condition and lose the best time for treatment. When symptoms such as chest and back pain appear, it is usually not the early stage of lung cancer, because chest and back pain may be caused by pleural adhesion or bone metastasis. If there are metastases in the above areas, it is already in the advanced stage of the tumor. Therefore, you should not ignore the small symptoms, and if you feel uncomfortable, you should go to the hospital immediately for examination, so as to achieve early prevention and treatment and improve the cure rate of the tumor.
