The statement of five manifestations of lung cancer on the skin is inaccurate. Lung cancer mainly manifests in skin changes of dermatomyositis and skin pigmentation due to the secretion of abnormal hormones. Lung cancer invading the liver also leads to manifestations such as dull skin and yellowish skin. However, skin symptoms are not common in lung cancer. Lung cancer is mainly characterized by cough, sputum, hemoptysis, chest pain, fever and other symptoms. Early stage lung cancer is often irritating dry cough, and later stage tumor continues to grow into the lumen can lead to persistent coughing up sputum and hemoptysis. Lung cancer directly invades chest wall or metastasizes to pleura will cause hidden chest pain. Tumor tissue necrosis of lung cancer can cause fever, or tumor-induced obstructive pneumonia can also lead to fever. Therefore, patients with related symptoms should go to the hospital in time to improve the examination, early diagnosis and early treatment in order to get a better prognosis.
