What are the specific symptoms and signs of lung cancer?

What are the specific symptoms and signs of lung cancer? Lung cancer originates from the bronchial mucosal epithelium. Those confined to the basement membrane are called carcinoma in situ. They can grow into the bronchial cavity and/or adjacent lung tissues, and can spread through lymphatic blood circulation or bronchial metastasis. So what are the specific symptoms and signs of lung cancer? Let our experts introduce them to you in detail.

The symptoms and signs of lung cancer include:

1. Pleural metastasis: chest pain, cancerous pleural effusion, etc.

2. Phrenic nerve paralysis: shortness of breath and chest tightness occur when the phrenic nerve is invaded

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

4. Difficulty in swallowing: It is caused by enlarged mediastinal lymph nodes compressing the esophagus, which in turn compresses the trachea and causes difficulty in breathing.

5. Localized wheezing is a localized wheezing sound that mostly occurs during the inhalation phase and does not disappear after coughing.

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

7. Shoulder and arm pain: When apical cancer compresses or invades the brachial plexus, radiating burning pain will occur in the shoulder and upper limb on that side.

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

9. Extrapulmonary signs: Common symptoms 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.

10. 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 symptoms such as dizziness, chest tightness, and shortness of breath.

11. Horner's syndrome: When the apex cancer of the lung compresses or invades the cervical sympathetic ganglion, the affected eyeball may become sunken, the upper eyelid may droop, the pupil may constrict, the palpebral fissure may be narrowed, the skin temperature of the upper chest on the affected side may increase, and there may be no sweating.

The above are the symptoms and signs of lung cancer. I believe you have already understood them. I hope that lung cancer patients will not give up on themselves and actively seek treatment.
