What does the symptom that cancer transfers to lung have

summary

There are many kinds of cancer, and different sites of occurrence will directly lead to different types of cancer, but cancer cells will not always exist in certain cells, it will metastasize over time. Let's talk about the symptoms of cancer metastasizing to the lungs.

What does the symptom that cancer transfers to lung have

First, the manifestations of metastatic lung tumor and the clinical manifestations of diagnosis of metastatic lung tumor. It is often found on routine chest X-ray examination, or recurrence 6 months to 3 years after radical surgery or radiotherapy. That is to say, the symptoms vary with the location of metastasis. If the metastasis occurs in the interstitial lung and is a solitary nodule, there is often no clinical symptoms.

Second, if the metastasis is located in the endobronchial membrane, the patient may have respiratory symptoms. Chest pain is common in patients with rib metastasis, small amount of hemoptysis may occur in a few cases with bronchial mucosa invasion, but massive hemoptysis may occur in patients with lung metastasis of choriocarcinoma. When the metastatic tumor invades the pleura, main bronchus or adjacent structures, the same symptoms as primary bronchogenic carcinoma may appear, such as cough, bloody sputum, chest pain, chest tightness, shortness of breath, etc.

Third, when the symptoms appeared earlier, it suggested that the metastasis involved the bronchus. If accompanied with mediastinal metastasis, the patient may present with hoarseness, superior vena cava syndrome, phrenic paralysis and esophageal or tracheal compression symptoms, occasionally with acute pulmonary embolism caused by tumor and progressive dyspnea. Metastatic lung cancer usually occurs 7 months to 3 years after the treatment of primary tumor. Lung metastasis occurs first in 15% - 30% of the patients, but the primary tumor has not been detected or is difficult to detect, which is more common in digestive system tumors.

matters needing attention

In this way, the metastasis of cancer to the lung is equivalent to the patient suffering from lung cancer, which will cause symptoms of lung cancer, such as dyspnea, cough and hemoptysis. This is a very serious phenomenon. If cancer is allowed to spread and metastasize, it may seriously threaten the safety of patients.
