What are the early symptoms of lung cancer? Introduction to the early symptoms of lung cancer

Generally speaking, cough is one of the early symptoms of lung cancer, but because it often resembles the symptoms of a cold or bronchitis, it is easy to be ignored and misdiagnosed. Therefore, people who have no chronic respiratory diseases before, especially those over 40 years old, should be alert to the possibility of lung cancer if their cough persists for more than three weeks after active treatment, and should be checked and diagnosed as soon as possible.

Since lung cancer patients are prone to some digestive tract symptoms, the relationship between lung diseases and the digestive tract is also very close. Especially when patients have digestive tract discomfort symptoms, they should not only focus on digestive tract diseases, but also pay attention to whether they have early symptoms of lung cancer. Don't wait until lung cancer becomes serious before regretting it.

What are the common early symptoms of lung cancer?

Generally speaking, cough is one of the early symptoms of lung cancer, but because it often resembles the symptoms of a cold or bronchitis, it is easy to be ignored and misdiagnosed. Therefore, people who have no chronic respiratory diseases before, especially those over 40 years old, should be alert to the possibility of lung cancer if their cough persists for more than three weeks after active treatment, and should be checked and diagnosed as soon as possible. For elderly patients with chronic bronchitis, the incidence of lung cancer is higher than that of ordinary people, but their early cough symptoms are easily confused with the original chronic cough, which often delays diagnosis.

At this time, we must pay attention to the changes in the nature and pattern of coughing. Due to the stimulation of cancer tissue on the bronchial mucosa, lung cancer patients often have irritating coughs and severe coughs with little sputum, which is inconsistent with the original seasonal pattern of onset. Active anti-infection treatment is ineffective and the symptoms are aggravated.

The second most common symptom of lung cancer is hemoptysis. It is often caused by cancer tissue invading the bronchial mucosa. The amount of hemoptysis is usually small, often manifested as bloody sputum, and can last for weeks or months or occur intermittently. Because the amount of hemoptysis is small or occurs intermittently, it is easy to be neglected.

According to statistics, more than half of lung cancer patients experience chest pain, especially for peripheral lung cancer, where chest pain can be the first symptom. This is due to the infiltration of the pleura by cancerous tissue. Chest pain is often fixed at the site of the lesion, and in the early stages it is often intermittent dull pain and discomfort. It can be aggravated by changes in body position, deep breathing, and coughing. Therefore, any chest pain that occurs at a fixed site for unknown reasons should be checked early. In short, coughing, hemoptysis, and persistent chest pain are important signs of lung cancer, especially for people over 40 years old with a history of long-term, heavy smoking, who should be more aware of the possibility of lung cancer.

Warm reminder: After contracting lung cancer, patients will experience symptoms such as weight loss due to excessive nutritional consumption. Some people even become so thin that "only ribs are left" within a month. Therefore, prevention and treatment of lung cancer must be started in the early stages. Do not wait until obvious symptoms of lung cancer appear before thinking about how to cure lung cancer.
