What symptoms does lung cancer cause? Lung cancer can cause 5 symptoms

Lung cancer is the most common of all cancers. Every year, a large number of people around the world suffer from lung cancer. Therefore, people are also more concerned about lung cancer. The harm caused by lung cancer includes many aspects. Many people may not know the symptoms of lung cancer. The following introduces the symptoms of lung cancer.

Lung cancer symptoms vary. Be alert to early extrapulmonary symptoms:

1. Male breast enlargement

About 10%-20% of male lung cancer patients have breast hypertrophy, some have unilateral hypertrophy, but most have bilateral hypertrophy, 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 hypertrophy.

2. Bone and joint symptoms

This type of symptom is 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.

3. Shoulder and back pain

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

4. Hoarseness

Lung cancer metastasis compresses the laryngeal nerve, which can paralyze the vocal cord muscles 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.

5. 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.
