What are the specific early symptoms of lung cancer? 10 early symptoms of lung cancer

The early symptoms of lung cancer are a problem that we must understand during the corresponding treatment process. Some people don't understand these, so they don't know where to start treatment. This is very important. Here are some specific early symptoms of lung cancer.

1. Localized wheezing usually occurs during the inhalation phase and does not disappear after coughing.

2. Hoarseness occurs when lymph node metastasis compresses or invades the recurrent laryngeal nerve.

3. Superior vena cava syndrome: Tumors compress or invade the superior vena cava, obstructing venous return and causing edema of the head, face, neck, and upper limbs, varicose veins and edema in the upper chest, accompanied by dizziness, chest tightness, shortness of breath, etc. When apical cancer compresses or invades the cervical sympathetic ganglion, the affected eyeball will be sunken, the upper eyelid will droop, the pupil will be constricted, the palpebral fissure will be narrowed, the skin temperature of the upper chest on the affected side will be increased, and there will be no sweating.

4. Shoulder and arm pain When the apex cancer of the lung compresses or invades the brachial plexus, radiating burning pain will appear in the shoulder and upper limb on that side.

5. Phrenic nerve paralysis: When the phrenic nerve is invaded, shortness of breath and chest tightness occur.

6. Common extrapulmonary signs include pain or hypertrophy of joints in the limbs, clubbing of fingers, multiple neuritis, myasthenia gravis, Cushing's disease, male breast hyperplasia, hypercalcemia, mental abnormalities, etc.

7. Dysphagia is caused by enlarged mediastinal lymph nodes compressing the esophagus, which in turn can cause dyspnea.

8. Pericardium invasion When the pericardium is invaded, pericardial effusion, shortness of breath, arrhythmia, heart failure, etc. will occur.

9. Pleural metastasis may cause chest pain, cancerous pleural effusion, etc.

10. Lung cancer metastasis The common sites of lung cancer hematogenous metastasis are bones, liver, brain, kidney, adrenal gland, subcutaneous tissue, etc. In addition, intramural metastasis is also common. Clinically, there are corresponding symptoms and signs depending on the different sites of metastasis.

The early symptoms of lung cancer are very obvious, so we must understand them when treating, otherwise the final treatment may not be very effective. Some people do not understand these and will take the wrong path of treatment. I hope these can help everyone cure the disease as soon as possible.
