What symptoms should I check to see if I have lung cancer

Lung cancer is the most common primary lung malignancy. Most lung cancers originate from the bronchial mucosal epithelium, so it is also called bronchial lung cancer. What are the possible symptoms of lung cancer ? What symptoms may indicate lung cancer?

Symptoms of early lung cancer are often not particularly obvious. People who have a history of smoking for many years, have a family history of disease, or work or live in areas with high pollution levels need to be extra vigilant. If you experience the following symptoms, you should go to the hospital for examination in time, because these are likely symptoms of lung cancer:

First, irritating dry cough cannot be cured for a long time.

Second, chest pain, and the pain is fixed in one place.

Third, there is blood in the sputum.

Fourth, unexplained bone and joint pain, or hypertrophy of the first joints of fingers and toes, and curved nail protrusions.

It is worth noting that about 15% of lung cancer patients have no symptoms at all in the early stage of lung cancer. When they come to see a doctor, the disease has already entered the late stage. Among them, only 20% of patients can be cured. Therefore, regular physical examinations are particularly necessary. We recommend that people over 40 years old should undergo chest X-ray or CT scans every year, which has a positive significance for early detection of lung cancer.

In recent years, with the development of modern CT imaging technology, low-dose CT (LDCT) technology has significantly improved the early detection rate of lung cancer. Compared with chest X-rays, LDCT has a higher sensitivity, and its detection rate for early lung cancer can reach nearly 50%, and the amount of radiation received by patients during the examination is much lower than that of ordinary CT examinations.

The above is an introduction to the symptoms of lung cancer, and I hope it can help you answer your questions. Experts remind: To increase the early detection rate of lung cancer, patients must first be more vigilant about lung cancer, have regular physical examinations, and conduct various examinations in a timely manner.
