How to check for lung cancer

If a person who has not been exposed to lung cancer has lung cancer, he or she may not know it. This requires going to the hospital for examination. With the continuous improvement of medical technology, the examination method for lung cancer is relatively simple. Let's take a look.

Generally, patients develop the disease without knowing it, and by the time the body shows abnormal reactions, the condition is already very serious. Therefore, in daily life, we should often do some examinations to avoid unnecessary harm. The following editor will introduce the commonly used test items for diagnosing lung cancer.

1. Chest MRI examination: It is a lung cancer examination without radiation damage. It can observe the image of the lung mass and its relationship with surrounding organs and large blood vessels in three dimensions from multiple aspects (including cross-section, coronal and sagittal planes, etc.), which is very helpful for the estimation of surgical resection.

2. Serum tumor markers: Many serum tumor markers related to lung cancer have been found. These markers may indicate the enhancement of carcinogenic factors or the degree of "detoxification" of certain carcinogens. Serum tumor markers of lung tumors may become valuable indicators for tumor staging and prognosis analysis, and can be used to evaluate the effect of treatment. The results of lung cancer markers must be combined with other test results and cannot be used alone for lung cancer examination.

3. X-ray examination: 98% of lung cancer patients can find abnormal signs from chest X-rays. X-ray fluoroscopy can provide dynamic observation and understand the changes in the bronchial lumen. This is a routine lung cancer examination item, which is both effective and economical.

4. Sputum exfoliated cell examination: It is one of the simplest and most important methods for lung cancer examination. It can detect exfoliated cancer cells in sputum, with a positive rate of up to 70%. However, it is generally required that the first deep sputum coughed up in the morning be sent for examination, and the examination should be continued for more than 3 days.

5. Bronchoscopy: It can directly observe the location of the lesion in the bronchus and its abnormal changes, aspirate secretions or take living tissue for pathological examination, obtain cytological or histological diagnosis, and consider the scope and method of surgical resection, or provide assistance in formulating chemotherapy plans.

The above are the examination methods for lung cancer. What do you think after reading it? There are many ways to examine lung cancer, so you need to go to the hospital to consult a doctor, because each hospital may have different examination methods.
