What are the key points to check for early detection of lung cancer? These tests are essential for preventing lung cancer

Nowadays, lung cancer is the most common cancer in the world. Many people have lost their young lives due to lung cancer, which is a pity. Therefore, each of us should do regular cancer prevention examinations. If we find problems and receive early treatment, we will not lose our lives so quickly. Let's follow the experts to read the common knowledge about lung cancer.

Lung cancer is divided into central lung cancer and peripheral lung cancer according to the different locations of the cancer mass. Early lung cancer refers to the first stage of cancer in the International Lung Cancer Staging System, that is, the cancer mass is less than 3 cm in diameter or more than 3 cm in diameter but has not yet developed local lymph nodes or distant metastasis. Common clinical symptoms of early lung cancer include cough, hemoptysis, fever and chest pain.

If you can be alert to these "clues" in your body and seek medical treatment promptly, you can find some early lung cancers in time. However, in real life, some early lung cancers lack or even have no clinical symptoms. Such early cases are often discovered accidentally during physical examinations. Clinical research data show that this asymptomatic early lung cancer is not uncommon, and the number of cases accounts for one-third of all early lung cancers.

Studies have found that most asymptomatic early lung cancers are peripheral lung cancers. This type of small cancer mass originates from the end of a small bronchus and is only about 2 cm in diameter. In the early stages of growth, it causes little irritation to the bronchial mucosa, and rarely or even does not cause symptoms such as coughing and coughing up blood. Naturally, people are not easy to detect and will not take the initiative to seek medical treatment. When the cancer grows rapidly or metastasizes to the second, third, or even fourth stage of middle and late stage lung cancer, it is difficult to treat and the prognosis is poor.

To detect asymptomatic early lung cancer, we must raise awareness and pay attention to regular cancer prevention examinations. People should learn some tumor knowledge and have a certain awareness of cancer prevention. If you belong to a high-risk group, you should take the initiative to have regular cancer prevention physical examinations. The "regular" here refers to 6 months in general.

Research has confirmed that annual checkups for high-risk groups still find relatively few early-stage lung cancers, but more patients in the middle and late stages. Therefore, it is recommended that "regular" should be set at 6 months. If high-risk groups take the initiative to have regular cancer prevention checkups, they can detect asymptomatic early-stage lung cancer in a timely manner, greatly improving the cure rate of lung cancer.

After listening to the explanations of professionals, we have learned some common sense about lung cancer examinations. We hope that everyone can do the examinations according to the above time nodes, so as to find problems earlier and receive surgical treatment earlier to reduce damage to the body. People who have not yet developed lung cancer should develop good habits and not smoke.
