Do lung cancer patients have to cough?

What are the symptoms of lung cancer? Does the symptoms of lung cancer necessarily include coughing? Conversely, does coughing necessarily mean lung cancer? In fact, lung cancer has no obvious symptoms in the early stages. Only a small number of lung cancer patients may experience symptoms such as irritating coughs, which are caused by tumors irritating the bronchial mucosa.

Most lung cancer patients will not develop lung cancer symptoms such as coughing and hemoptysis until the disease reaches the middle and late stages. Among them, lung adenocarcinoma accounts for about 25% of primary lung cancers. It is mostly located around the lungs, close to the pleura. Adenocarcinoma has no close relationship with smoking and is often discovered during chest X-rays and CT scans. Although adenocarcinoma grows slowly, some patients will have blood metastasis. Generally, primary lung cancer is not discovered until symptoms of brain metastasis appear.

According to relevant statistics, more than 70% of lung cancer patients are already in the middle or late stages when they are first diagnosed, which is one of the most important reasons for the poor treatment effect of lung cancer. According to relevant tumor experts, in medicine, lung cancer is divided into four stages. The 5-year survival rate of patients in stage III or IV is less than 20%, and most patients will die within 2 years of illness. However, if the tumor can be found in stage I, the patient is likely to recover through surgical treatment, and the 5-year survival rate can reach 70%-80%. If regular treatment and regular follow-up are given, the patient can live like a healthy person. However, this proportion is only about 20% clinically. Even in stage II, the 5-year survival rate after treatment can reach 50%.

This is because it takes time for a tumor to grow and metastasize. If it can be discovered and treated in time before metastasis, the cure rate of lung cancer will definitely be effectively improved. So how can early detection be achieved? People with the following conditions should pay more attention:

1. Smokers: The risk of lung cancer for smokers is 9-10 times that of non-smokers, and for heavy smokers it is even 10-25 times. In addition, if your home is often filled with smoke, even if you don't smoke, your risk of developing lung cancer will be very high.

2. People who are frequently exposed to pollutants: traffic police, teachers who use a lot of chalk for a long time, people who are exposed to asbestos, ionizing radiation, microwave radiation, etc. at work, have a much higher risk of lung cancer.

3. People who have had lung diseases: such as emphysema, pneumonia, etc.

From the above we can see that the symptoms of lung cancer are generally not obvious, so regular physical examinations are very important.
