How to read lung cancer CT report What are the early symptoms of lung cancer

CT, X-ray and other imaging examinations are the main means of diagnosing lung cancer. In the early stage of lung cancer, CT can show irregular thickening of the bronchial wall, stenosis of the lumen, nodules in the lumen and other changes. In the late stage, CT can clearly see the edge, shape, peritumoral manifestations, internal structure and density changes of the mass. When patients suspect lung cancer, they should go to the hospital for examination and diagnosis of the cause in time.

As our living standards improve, the incidence of lung cancer is also increasing. The occurrence of lung cancer is mainly related to smoking, air pollution and dietary health. After suffering from lung cancer, many people's symptoms are not obvious. Common symptoms include coughing, chest tightness, shortness of breath, blood in sputum, etc., which are easily confused with other diseases. We know that the main method for diagnosing lung cancer is CT, so how to read the lung cancer CT report?

Although the incidence of lung cancer is high, it is difficult to detect it in the early clinical stage. The main reason is that there are no specific symptoms for early lung cancer. Some symptoms may indicate lung cancer, but they are not directly related to lung cancer, such as irritating dry cough, long-term coughing up blood or lung inflammation, and repeated anti-inflammatory treatment is ineffective. These are all signs of lung cancer. Generally, when lung cancer patients are diagnosed with the disease, they are already in the middle and late stages. Some patients are diagnosed with advanced lung cancer and miss the opportunity for surgery. The diagnosis of lung cancer mainly includes X-rays, chest CT and other imaging examinations.

CT is the main means of examining lung lesions. CT can clearly understand the corresponding space-occupying lesions, especially the size, shape, distribution and density of tumors and cancers. Because lung cancer grows very fast, it may be asymmetrical around the lung cancer, which is called the lobulation sign in imaging. It protrudes like a cauliflower, with a leaf or a leaf-like lobulation change. Lung cancer also has other symptoms, including pleural indentation. CT has a clear scientific basis for judging the benign and malignant nature of this disease, and the size and boundaries of the lesions can be learned from the corresponding examination report. The boundaries of benign lesions are relatively clear, while the boundaries of malignant lesions are blurred. Calcification can occur in many benign lesions and is also the main basis for identification.
