What symptoms indicate lung cancer? Four abnormal manifestations may be symptoms of lung cancer

Even if you are unfortunately diagnosed with lung cancer, you should have confidence in curing it and not be defeated by a thin test report, especially in the early stages of lung cancer. If we can find clues of lung cancer and treat it immediately, then the disease can be cured. In order to prevent other healthy people from repeating the same mistakes, you must understand the early symptoms of lung cancer.

What symptoms indicate that a patient has 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.

Lung cancer patients should note that lung cancer is actually an occupational disease. Especially in workshops that produce chemicals, there are a lot of lung cancer patients. So, if you feel that you have recently developed early symptoms of lung cancer, you should improve your working environment. Even if you have to give up your original job, it is worth it.
