Is chest X-ray useful for detecting lung cancer?

Many people do not know which examination methods are better when checking for lung cancer. And many people think that chest X-ray can directly check for lung cancer. Therefore, in response to this problem, our experts have given an explanation to let us know that it is not easy to check for lung cancer.

Experts say: It is very difficult to detect early-stage cancer, and there is currently no cost-effective method for detecting lung cancer. Many units now organize a physical examination every year, but it is not a cancer prevention physical examination, but just a health physical examination. However, it is okay to find high blood pressure and high blood sugar.

It is difficult to detect lung cancer simply by taking a chest X-ray. Generally, we recommend that people at high risk of lung cancer who are over 40 years old, smoke for many years, or have a family history of cancer undergo a low-dose spiral CT scan once a year. Spiral CT scans have very high resolution and can detect crystals smaller than 4 mm. Therefore, there are ways to detect lung cancer, and you don't have to worry about it.

Ordinary chest X-ray cannot directly detect lung cancer, but lung shadows can indicate lung cancer. If the mass is relatively small and located in the mediastinum, it cannot be seen in the early stage. Ordinary chest X-ray can only show relatively obvious lesions. Some relatively small lesions cannot be seen clearly, such as the location of the shadow. The resolution of chest X-ray is relatively low. Therefore, it is best to use other methods to detect lung cancer.

So, now we know what methods to use when checking for lung cancer. Therefore, we can now use the methods to check for lung cancer. However, we must pay attention after checking for lung cancer. If lung cancer is diagnosed, it must be treated in time. Do not think that you do not need treatment if you do not have any uncomfortable symptoms. The sooner we treat lung cancer, the better.
