　　神经系统症状：肺癌脑转移可出现头痛、呕吐、突然昏迷、失语、偏瘫等神经系统症状，因肺部症状不明显，常误诊为及血栓、脑肿瘤。
　　肩背痛：肺外围型肺癌常向后上发展，侵蚀胸膜，累及肋骨和胸壁组织，从而引起肩背痛。这类患者很少有呼吸道症状。
　　骨关节症状：此类症状较为多见。由于肺癌细胞可产生某些特殊的内分泌激素（异源性激素）、抗原和酶，这些物质运转作用于骨关节部位，而致骨关节肿胀疼痛，常累及胫、腓、尺、桡等骨及关节，指趾末端往往膨大呈杵状指，X线摄片检查可见骨膜增生。
　　声音嘶哑：肺癌转移灶压迫喉神经，可使声带单板机痹而致声音嘶哑。由于肺癌的转移灶在早期即可出现，并县城转移灶有时可长得比原发灶快，因此转移灶的临床表现可先于原发灶出现。
　　男性乳房肥大：男性肺癌患者，约有10%－20%出现乳腺肥大，有单侧肥大，但多数为双侧肥大，而且这种症状出现时间比咳嗽、痰中带血、胸痛、气促等肺部症状早一年左右。这是因为某些肺癌细胞能分泌出绒毛膜促性腺激素，这种激素可引起乳腺组织增生，使乳房肥大。

Shoulder pain: peripheral type of lung cancer often back on the development, erosion pleura, involving the ribs and chest wall tissue, causing shoulder pain. Few of these patients with respiratory symptoms.
Bone and joint symptoms: these symptoms are more prevalent. Because lung cancer cells can produce some special endocrine hormone (heterologous sex hormone), antigen and enzyme, the role of these substances in bone joints running an extent which rendered bone and joint swelling and pain, often involving the tibia, fibula, foot, radius and other bone and joint , Zhi Zhi was the end of clubbing often swollen, X-ray examination showed periosteal proliferation.
Voice hoarse: metastasis of lung cancer laryngeal nerve compression, paralysis can Erzhi SBC vocal hoarseness. Because lung cancer metastasis can occur early, and sometimes county metastases than in primary tumors grow fast, so clinical metastases may occur before the primary tumor.
Male breast hypertrophy: male patients with lung cancer, there are about 10% -20% of breast hypertrophy, with unilateral hypertrophy, but most were bilateral hypertrophy, and this time than the onset of symptoms as cough, bloody sputum, chest pain, shortness of breath, etc. pulmonary symptoms about one year earlier. This is because some cancer cells can secrete human chorionic gonadotropin, the hormone can cause breast tissue to breast hypertrophy.
