What are the external symptoms of lung cancer? Five common external symptoms of lung cancer

The typical symptoms of lung cancer are undoubtedly cough, chest pain, shortness of breath and other lung manifestations. Generally, these manifestations come from the symptoms outside the lungs, and they appear faster than the symptoms outside the lungs, making people unaware. Since these symptoms seem different from the symptoms of lung cancer, what are the external symptoms of lung cancer?

1. Bone and joint symptoms: These symptoms are more common. Lung cancer cells can produce certain special endocrine hormones (xenohormones), antigens and enzymes, which act on the bone and joint parts, causing bone and joint swelling and pain, often involving the tibia, fibula, ulna, radius and other bones and joints. The ends of the fingers and toes often swell and become clubbed, and X-ray examinations can show periosteal hyperplasia.

2. Shoulder and back pain: Peripheral lung cancer often develops posteriorly and upwards, eroding the pleura, involving the ribs and chest wall tissue, thus causing shoulder and back pain. Such patients rarely have respiratory symptoms.

3. Hoarseness: Lung cancer metastasis compresses the recurrent laryngeal nerve, which can paralyze the vocal cord muscles and cause hoarseness. Since lung cancer metastasis can appear in the early stage and metastasis sometimes grows faster than the primary lesion, the clinical manifestations of metastasis can appear before the primary lesion.

4. Neurological symptoms: Brain metastasis of lung cancer may cause neurological symptoms such as headache, vomiting, sudden coma, aphasia, hemiplegia, etc. Because the lung symptoms are not obvious, they are often misdiagnosed as thrombosis or brain tumors.

5. Male breast enlargement: About 10%-20% of male lung cancer patients have breast enlargement, some have unilateral enlargement, but most have bilateral enlargement. Moreover, this symptom appears about a year earlier than other lung symptoms such as cough, blood in sputum, chest pain, and shortness of breath. This is because some lung cancer cells can secrete chorionic gonadotropin, which can cause breast tissue hyperplasia and breast enlargement.

From the above, we can see that lung cancer is a disease that should not be underestimated. Bone and joint symptoms, shoulder and back pain, hoarseness, nervous system symptoms, and male breast hypertrophy may all be important factors in causing lung cancer, so we must protect our bodies. The album reminds: If you have any of the above 5 symptoms, you should seek medical diagnosis and treatment in time.
