What are the symptoms caused by lung cancer tumor compression and metastasis

Among the many lung cancer patients, many patients have non-lung cancer symptoms as the first symptom, and go to the hospital for examination, and the result is lung cancer. The so-called "non" lung cancer symptoms refer to these symptoms that are not caused by the primary lesion of lung cancer, but are adverse reactions to other parts of the body due to tumor compression or metastasis. These symptoms are as follows:

1. Chest pain: Pain in any part of the body from the head and neck to the lowest rib is collectively referred to as chest pain. There are many causes of chest pain, such as chest colic, pneumonia, bronchitis, etc. However, in about 30% of lung cancer patients, tumors will directly invade the pleura, ribs and chest wall, causing patients to experience persistent chest pain.

2. Dyspnea: Dyspnea is manifested as changes in respiratory rate, depth, and rhythm. Various lung diseases can cause dyspnea. If a tumor compresses the large airways, the patient may experience inspiratory dyspnea.

3. Difficulty swallowing: If the tumor invades or compresses the esophagus, the patient may experience difficulty swallowing. At this time, the patient rarely associates it with lung cancer. If the invasion is more serious, it may cause bronchoesophageal fistula and lead to lung infection.

4. Hoarseness: Hoarseness can be caused by many reasons, so few people would associate it with lung cancer. However, if the tumor directly compresses or metastasizes to the mediastinal lymph nodes and then swells and compresses the recurrent laryngeal nerve, it will cause hoarseness.

5. Superior vena cava syndrome: When the tumor invades the mediastinum and compresses the superior vena cava, the venous return to the head is blocked, and the patient will experience edema of the head, face, neck and upper limbs, as well as headaches, dizziness or vertigo.

6. Homer syndrome: The tumor located at the apex of the lung invades the sympathetic ganglion of the neck, causing ptosis, pupil constriction, and enophthalmos on the affected side, and no or little sweating on the forehead and chest wall on the same side; compression of the brachial plexus can cause pain and paresthesia in the ipsilateral shoulder joint and inner side of the upper limb, especially at night.
