Common symptoms of lung cancer and how to detect them? Common methods of detecting symptoms of lung cancer

With the development of society, the incidence of lung cancer, a malignant tumor, is increasing worldwide, and the incidence population is becoming more and more extensive. It has a great impact on the life and work of patients. Here are some common methods for detecting lung cancer symptoms:

1. Diagnostics cannot be ignored! The histopathology or cytology required for lung cancer diagnosis can be performed by sputum cytology, pleural effusion cytology, pleural slices, ultrasound-guided slices, CT-guided slices, bronchoscopic slices and cytology, and even fine needle aspiration or slices of lymph nodes. Deng Jianming, Department of Cardiothoracic Surgery, Guangdong Provincial Second People's Hospital, can use chest CT, abdominal CT or ultrasound, brain CT, bone scan, pleural effusion cytology, pericardial effusion cytology, thoracoscopic lymph node slices, positron emission tomography (PET), etc. for staging.

2. As we all know, chest pain symptoms are always more obvious in patients in the middle and late stages. At the same time, mild chest pain is also quite common in early lung cancer cases. Most of them are irregular dull pains caused by inflammation of the parietal pleura and chest wall. Continuous and severe chest pain often indicates that the cancer has directly spread and invaded the pleura and chest wall tissues, and the cancer has entered the late stage.

3. Many patients will always show symptoms of cough and sputum in the early stage, and severe cases will have different degrees of hemoptysis. The most common symptom of early lung cancer is the irritating cough caused by the growth of the tumor under the bronchial mucosa. Most of them are dry coughs or a small amount of white foamy sputum, which can be easily mistaken for colds. Patients with smoking habits often have mild coughs, which are often ignored until the cough persists and they go to the doctor for examination. Another common early respiratory symptom is bloody sputum, usually with blood spots and blood streaks in the sputum, and occasionally intermittent small amounts of hemoptysis; large amounts of hemoptysis are only seen in a few cases of bronchial adenomas.

4. Chest tightness and shortness of breath: When the cancer grows and causes varying degrees of obstruction of larger bronchi or when pleural effusion occurs, symptoms such as chest tightness, wheezing, and shortness of breath may occur.

Through the simple introduction above, I believe everyone has a certain understanding of the common methods of detecting lung cancer symptoms. The incidence of lung cancer is high, and how to prevent it well depends on the degree of common sense of the disease. Therefore, everyone should learn more about lung cancer and take good prevention measures.
