What tests should be done for lung cancer? These tests are necessary to diagnose lung cancer

In life, many people think that hoarseness must be a problem with the throat. However, they do not know that lung cancer can also cause hoarseness and will accompany the patient for a long time. Since this symptom often occurs in the early stages of lung cancer and is mostly not accompanied by other disease symptoms, it is easy for patients to delay the treatment of the disease. Therefore, patients must pay attention to this symptom and get checked as soon as possible once it occurs.

Affected by the serious impact of air pollution, more and more people are suffering from lung diseases. In addition, many people in life do not pay enough attention to their own health. Even if they have physical abnormalities, they will not choose to seek medical treatment in time, which delays their illness and leads to the occurrence of lung cancer. Especially those who have long-term hoarseness should be checked as soon as possible to rule out lung cancer. So, what examinations should be done for long-term hoarseness? Let us take a closer look.

Chest X-rays and chest radiographs are needed to screen for lung cancer. If it is lung cancer, a round shadow can usually be found in the lungs during the examination, and it may even be accompanied by pneumonia, atelectasis, and some fluid in the chest cavity. Chest X-rays, CT, and MRI examinations can determine the size of the tumor, as well as the relationship between the tumor and the bronchi, lung segments, and lobes. If necessary, bronchial iodized oil contrast imaging is also required.

Bronchoscopy can more directly detect the lesions and can also perform pathological biopsy. This examination is beneficial for later treatment and medication, so it is also one of the most critical examination items. If the patient has sputum, repeated sputum examinations can be used to find evidence of cancer. Usually, the test results are not positive, which is also very valuable for diagnosing lung cancer.

Patients can also be diagnosed with lung cancer through lung puncture, which usually results in a positive test result. When lung lesions have not been confirmed, they can be confirmed through superficial lymph node puncture and biopsy. During the examination, enlarged lymph nodes in the neck and clavicle can be found. Lymph node puncture can be used to extract cells for biopsy to better diagnose the disease.

I believe everyone already knows what tests are needed for long-term hoarseness. After lung cancer occurs, patients will not only have long-term hoarseness symptoms, but also neck and facial edema symptoms. Some patients will even have symptoms such as bloody sputum and coughing up blood. Even if your condition is not serious, if it accompanies you for a long time and does not heal, you should go to the hospital as soon as possible to find out the cause, so as to effectively prevent and treat lung cancer.
