Chest pain in lung cancer may hurt all the time, or it may hurt at times and not at all. There is no obvious pattern of chest pain symptoms of lung cancer. If the tumor tissue compresses the blood vessel and nerve, the patient may have persistent pain; if the tumor tissue invades the pleura, it may cause irritation to the chest wall when moving, causing intermittent pain. In case of unexplained chest pain, it is recommended to go to the hospital as soon as possible to improve chest CT, fiberoptic bronchoscopy and other related tests and examinations to clarify whether the patient is suffering from lung cancer. Once diagnosed with lung cancer, the patient should cooperate with the doctor as soon as possible to receive surgery, radiotherapy, chemotherapy and other treatments, so as to prolong the survival time of the patient as much as possible.
