I won't elaborate on the horror of cancer. As the king of cancer, lung cancer is like a demon hidden in the body, which few people can detect. Once found in some tests, it is basically advanced, so in modern medicine, the survival rate of lung cancer is very low, and it is a miracle to persist for more than 5 years. So are there any warning signs before lung cancer occurs?

Speaking of this, we should popularize a medical term-pulmonary nodule, and its appearance can be said to be the key to measure the early and late stages of lung cancer.

In daily life, some well-known warning signals before the arrival of lung cancer are nothing more than the following, but these warning signals are similar to other diseases, and may even have become the unique characteristics of lung cancer, so many people are still careless and difficult to distinguish. For example, hoarseness, cough, fever, shoulder pain, nervous system symptoms, male hypertrophy and other symptoms may be obvious at a glance, and these symptoms often appear in other diseases, so it is not easy to distinguish lung cancer by them. So how to predict the early and late stages of lung cancer through lung nodules?

On the other hand, this method of identifying pulmonary nodules still requires everyone to have a certain health awareness and regular physical examination. Of course, the method of checking lung nodules is not troublesome. Just take an X-ray to check the pulmonary nodules.

According to Professor Zhang from China Traditional Chinese Medicine Oncology Clinic, this kind of pulmonary nodule is actually a shadow of the lung, and it is called pulmonary nodule when it cannot be diagnosed as a certain disease. According to the size and shape, it can be roughly divided into three types.
