What are the symptoms of lung cancer? If you have these 5 symptoms, beware of lung cancer

Lung cancer is the main cause of human death. It should be noted that the incidence of lung cancer is very high all over the country. This is closely related to people's current lifestyle and living environment. The incidence of lung cancer is very high. Therefore, we should understand the prevention of lung cancer and pay attention to prevention. The following is an introduction to the 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 laryngeal nerve, which can paralyze the vocal cord nerve and cause hoarseness. Since lung cancer metastasis can appear in the early stage and sometimes grow 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, and 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.

One thing that must be noted is that the early symptoms of lung cancer are not obvious, but there are often certain mild symptoms, which are very easy to be ignored by patients. For example, early patients will experience chest tightness and pain, or cough, etc. As the disease progresses, these symptoms will gradually become clear.
