Diagnosis methods for lung cancer with different symptoms

What are the methods for diagnosing lung cancer? Everyone should know that generally the symptoms of the same disease are different. So what are the diagnostic methods for lung cancer with different symptoms? Let the experts summarize the answers to these questions for us.

1. Pulmonary inflammation

1. Lung abscess: When the central part of lung cancer necrotizes and liquefies to form a cavity, the X-ray findings are easily confused with lung abscess. Lung abscess has obvious infection symptoms in the acute stage, with a large amount of purulent sputum. On X-rays, the cavity wall is thin, the inner wall is smooth, and there is often a fluid level. The lung tissue around the abscess is often infiltrated, and the pleura has inflammatory changes. This is a commonly used diagnosis method for lung cancer.

2. Bronchopneumonia: Obstructive pneumonia caused by early lung cancer is easily misdiagnosed as bronchopneumonia. Bronchopneumonia develops rapidly, with severe infection symptoms and obvious systemic infection symptoms. The diagnosis of lung cancer depends on whether the X-ray shows flaky or spotted shadows with fuzzy boundaries, uneven density, and is not limited to one lung segment or lobe. After anti-infection treatment, the symptoms disappear quickly and the lung lesions are absorbed quickly.

2. Other lung tumors

1. Benign lung tumors: such as hamartoma, fibroma, chondroma, etc., sometimes need to be diagnosed with peripheral lung cancer. Generally, benign lung tumors have a long course, grow slowly, and are mostly asymptomatic. Lung cancer can be diagnosed with X-rays. This type of lung cancer is shown as a round mass with uniform density and calcification points. The contour is neat and there are no lobes.

2. Bronchial adenoma: It is a low-grade malignant tumor. The age of onset is younger than lung cancer and it is more common in women. The clinical manifestations are similar to those of lung cancer, with irritating cough and repeated hemoptysis. X-rays may show obstructive pneumonia or localized atelectasis of segments or lobes. Soft tissue shadows in the lumen can be seen on tomographic films. Lung cancer should also be diagnosed at this time.

The above is an introduction to the knowledge about the diagnosis of lung cancer. Do you understand it? If you still want to know what precautions to take, you are welcome to consult experts online.
