Early symptoms and metastasis of lung cancer?
summary
Lung cancer will spread and metastasize in the middle and late stage. In the early stage, the symptoms of lung cancer are not obvious. Generally, if the patient has a long-term cough, chest tightness, dyspnea or expectoration, the sputum is bloody. Early symptoms and metastasis of lung cancer? Now let me tell you something.
Early symptoms and metastasis of lung cancer?
In clinic, the most easily metastatic place of lung cancer is the lymphatic system. If lung cancer metastases to lymph nodes, the clinical symptom is that patients will have lymph node enlargement, most of the lung cancer patients will have clavicular lymph node enlargement, enlarged lymph nodes will not have pain.
In addition, it is easy to have bone metastasis. Generally, the most obvious symptoms are leg pain or chest and back pain. However, the appearance of these symptoms does not mean that there must be bone metastasis. We need to do a bone scan and see a film to determine whether it is bone metastasis.
The most serious case of lung cancer is brain metastasis. The clinical symptoms of brain metastasis are headache and vomiting, and some patients also have vision loss. Patients with intracranial pressure will rise, generally patients need to use mannitol for treatment, brain metastasis treatment is very difficult, because chemotherapy drugs can not pass through the brain barrier, so the treatment effect of chemotherapy for brain metastasis is very poor.
matters needing attention
In addition, it is also prone to metastasis of adjacent organs. For example, metastasis to the liver may lead to ascites, and some patients may metastasize to the stomach, forming a new focus of gastric cancer. In short, because of the characteristic of diffusion and metastasis of malignant tumor, there are many sites of metastasis.
