What are the examination methods for peripheral lung cancer? It is best to do these examinations for peripheral lung cancer

Lung cancer above the respiratory bronchioles and below the tertiary bronchus is called peripheral lung cancer, with adenocarcinoma being the most common. Early peripheral lung cancer will not show obvious clinical symptoms. Generally, patients will not experience fever and chest pain until the disease reaches the late stage. In recent years, the application of multi-slice spiral CT has achieved early diagnosis of peripheral lung cancer.

The main clinical manifestations of peripheral lung cancer are fever and chest pain, among which chest pain is the most important clinical symptom. The pain is often limited to a certain part of the shoulder or chest. Late-stage patients often have severe chest pain symptoms. If peripheral lung cancer is not treated in the early stage, it will endanger life. So what are the examination methods for peripheral lung cancer?

1. Peripheral lung cancer can be diagnosed through X-ray examination. The X-ray examination results of peripheral lung cancer usually show isolated elliptical or circular mass shadows around the lung field. It is an irregular mass shadow with small notches or lobes, rough and blurred edges, and thin and short spur shadows. The spur sign is the main imaging manifestation of peripheral lung cancer. The spurs that appear are divided into long spurs and short spurs. Short spurs are very important for the diagnosis of peripheral lung cancer. If peripheral lung cancer blocks the bronchial lumen, the patient may have atelectasis or staged pneumonia, and the center of the tumor will form an uneven liquid plane on the inner wall. X-ray examination can observe that the pleura is in a concave state and its shape is destroyed. On the lung X-ray film, it can be seen that there are a large number of strip-like blurred shadows in the range from the pleura to the hilar mass. In addition, the internal density of peripheral lung cancer tumors is uneven, and X-ray examinations can show dot-like low-density shadows.

2. Peripheral pneumonia can be diagnosed through CT examination. The current CT examination has a high resolution and can clearly display shadow masses in the lung field. It can detect early peripheral lung cancer missed by X-ray films. CT examination can observe the mediastinal lymph node metastasis and the hilar condition of peripheral lung cancer, and provide detailed information such as the internal condition of the tumor cavity and the amount of pleural effusion. CT examination has important clinical value for the diagnosis and treatment of peripheral lung cancer.

Peripheral lung cancer is relatively difficult to treat and is very harmful to the human body. X-rays have become the main means for patients to screen for peripheral lung cancer due to their high cost-effectiveness. Peripheral lung cancer will show cavitation signs, spiculation signs, pleural indentation signs and lateral edge line signs during examination. If signs of peripheral lung cancer are found during the examination, it is necessary to actively cooperate with the doctor for treatment.
