What are the self-diagnosis methods for lung cancer? Several self-diagnosis methods for lung cancer

Lung cancer is causing more and more people to suffer. Many people will have symptoms such as coughing up blood or fever, and they will wonder if they have lung cancer. In fact, you don’t have to worry. Today, I will introduce several ways to self-diagnose lung cancer for you to self-diagnose in your life:

One of the typical symptoms of lung cancer is cough: Cough is a common first symptom of lung cancer and is the first thing patients should pay attention to when self-diagnosing. About 60% of patients have this symptom. This is because the tumor grows under the bronchial membrane, and the foreign body sensation causes an irritating cough or choking cough, with no sputum or a small amount of white sputum. At this time, you must not be confused by the choking cough caused by smoking or chronic bronchitis. If you find that the cough caused by smoking or chronic bronchitis has suddenly intensified or an irritating cough different from usual since a certain period, especially for middle-aged and elderly people, you should pay attention to the fact that it may be an early sign of lung cancer and you should go to a regular hospital for treatment in time.

The second typical symptom of lung cancer is fever: It occurs in about 30% of lung cancer patients. When the trachea is blocked by the tumor, the secretions at the distal end are retained and cause inflammation. Fever is a manifestation of inflammation. Symptoms can be improved after early anti-inflammatory treatment. However, if the same part is repeatedly inflamed or pneumonia does not heal for a long time, the possibility of lung cancer should be considered, and it is necessary to go to a regular medical institution for diagnosis.

The third typical symptom of lung cancer is blood in sputum: this is also the first symptom of lung cancer. Patients should carefully observe their sputum when conducting self-diagnosis. This accounts for about 40% of lung cancer patients, but its diagnostic significance is more important than coughing. It is characterized by repeated and intermittent sputum with blood or blood spots, while large amounts of hemoptysis are rare. Therefore, if you see blood in your sputum, you should seek medical attention as soon as possible. Even if the chest X-ray is negative, you should observe carefully and do not easily rule out lung cancer. This may be a signal of early latent lung cancer. At this time, the diagnosis method of lung cancer must be carefully selected.

The fourth typical symptom of lung cancer is chest pain: This symptom is not very obvious. Most of the time, it occurs when coughing. Chest pain and chest discomfort are sporadic in the early stage, but persistent in the later stage. The pain is particularly obvious when coughing hard or changing body position. Patients should be more vigilant. When self-diagnosing, patients should determine whether they feel chest pain.

In addition to these typical symptoms of lung cancer, there is another important diagnostic method for people at high risk of lung cancer, that is, people who usually have chronic lung diseases and suddenly develop severe cough, blood in sputum, persistent fever, or repeated inflammation in the same part of the lungs, especially segmental inflammation, which develops slowly and has mild symptoms. After antibiotic treatment, if the symptoms disappear or the inflammation is slowly absorbed or always exists, you must seek medical attention immediately for a comprehensive lung cancer diagnosis to avoid missing the most effective period of treatment.

Through the introduction above, I believe everyone has a better understanding of how to conduct self-diagnosis. In daily life, we should always pay attention to whether we have the above symptoms. Once they appear, we should go to a regular hospital in time for scientific examination and treatment.
