Obstructive pneumonia and lung cancer

If you can't see obstructive pneumonia, you think it must be lung cancer. This can be seen mainly through CT. Under bronchoscope, you can see new organisms appearing in obstructive pneumonia. In this case, the possibility of lung cancer is very high. Obstructive pneumonia is not necessarily lung cancer, because sometimes some other chronic inflammations can also cause obstructive pneumonia, such as chronic pneumonia, which may cause obstructive pneumonia. You can go to the hospital for examination to find out the pathogen of obstructive pneumonia, and then treat it according to the pathogen to avoid aggravating the inflammation.

What targeted drugs should be used for brain metastasis of lung cancer?

Patients with brain metastasis of lung cancer take some targeted drugs according to the results of genetic testing. Lung cancer also has a gene mutation ALK. Alectinib, ceritinib and crizotinib are available targeted drugs for ALK, of which crizotinib is the first generation ALK. Alectinib and ceritinib are the second and third generation targeted drugs for brain metastasis of ALK-positive non-small cell lung cancer. When lung cancer metastasizes to the brain, eat more high-calorie, high-vitamin, high-protein foods, and eat more anti-cancer foods, such as whole grains, meat, eggs, beans, etc.

The difference between lung nodules and lung cancer

Lung cancer lesions are round or oval in shape and can be divided into lobe or memory shape, with spiculated edges, and may be accompanied by localized pneumonia or atelectasis. The main difference between pulmonary nodules and lung cancer is that the concepts, causes, and treatments of the two are different. Pulmonary nodules are a multi-system, multi-organ granulomatous disease, the cause of which is still unclear, but may be related to pathogen infection, tuberculosis, pulmonary fibrosis and other factors. If there is calcification in the nodule, the shape of the nodule is divided into lobe shape, the edge has spiculated edges, there is air bronchogram in the nodule, and the nodule is a true ground glass specimen change sign, then it is more likely to be considered a malignant tumor.
