Introduction to several major extrapulmonary symptoms of lung cancer

Among the many symptoms of lung cancer, some symptoms do not appear in the patient's lungs, but in other parts of the body. They are often misdiagnosed as other diseases, which is not conducive to the correct treatment of lung cancer. So what are the main symptoms of lung cancer ? Let's talk about the main symptoms of lung cancer.

In general, the main symptoms of lung cancer are:

1. Bone and joint symptoms: This type of lung cancer 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.

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. This type of patient rarely has respiratory symptoms.

3. Hoarseness: Lung cancer metastases compress the laryngeal nerves. The symptoms of lung cancer can cause vocal cord paralysis and lead to hoarseness. Since lung cancer metastases can appear in the early stages and sometimes grow faster than the primary lesions, the clinical manifestations of metastases may appear before the primary lesions.

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

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

The above-mentioned lung cancer symptoms are easy to be ignored and need special attention. I hope that reading this article will be helpful to you. If you have these lung cancer symptoms, you must go to the hospital for treatment in time to avoid delaying the disease and causing serious effects on the patient.
