Experts explain what are the common symptoms of lung cancer

Lung cancer is a common disease among middle-aged and elderly people, and the mortality rate of lung cancer is very high. Do you know the common symptoms of lung cancer? Regarding this question, let our experts explain to you the common symptoms of lung cancer.

What are the common symptoms of lung cancer? The following is an introduction to the common symptoms of lung cancer:

1. Clubbing

Clubbing is also called drumstick finger. It is characterized by hypertrophy of the first segment of the fingers and toes, protrusion and bending of the nails, and is often accompanied by pain. According to foreign reports, 21% of lung cancer is accompanied by clubbing in the early stage, and most of them disappear after lung surgery.

2. Male breast enlargement

About 10% to 20% of male lung cancer patients experience breast enlargement, most of which is bilateral, and the onset time is about one year earlier than lung symptoms such as cough, blood in sputum, chest pain, and shortness of breath. This is because some lung cancer cells can secrete chorionic gonadotropin, which can cause breast tissue hyperplasia and breast hypertrophy.

3. Chronic cough

In general, cough is one of the early and most common symptoms of lung cancer patients. Since it often resembles the symptoms of a cold or bronchitis at the onset, it is easily ignored. Therefore, people who have never had 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 3 weeks after active treatment, and should be checked and diagnosed as soon as possible. As for elderly patients with chronic bronchitis, the incidence of lung cancer is higher than that of the general population, but their early cough symptoms are easily confused with the original chronic cough, so there are many cases of delayed diagnosis. At this time, it is necessary to pay attention to changes in the nature and regularity of cough. 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 four-season disease pattern. Active anti-infection treatment is ineffective, and the symptoms are aggravated.

4. Chest pain

According to statistics, more than half of lung cancer patients experience chest pain, especially in peripheral lung cancer. Chest pain can be the first symptom, which is caused by cancer tissue infiltrating the pleura. Chest pain is often fixed at the site of the lesion, and in the early stage, it is mostly intermittent pain and discomfort. It can be aggravated by changes in body position, deep breathing and coughing.
