Last Updated: 2024/11/22, In all types of cancer, there are primary and secondary, of which secondary accounts for a large proportion, so there are precancerous lesions. And secondary lung cancer and other cancers, treatment is more complex and difficult, because it is prone to cancer.

In each category of cancer, there are primary and secondary, and secondary accounts for a large proportion of both, so there is a precancerous lesion. The treatment of secondary lung cancer and other cancers is more complicated and difficult, because cancer metastasis is easy to occur, so early treatment of various general diseases and early primary lung cancer is very important.

Bilateral lung cancer

Primary lung cancer accounts for a relatively small proportion of lung cancer, but from a wider range of the country, it can prevent and treat primary lung cancer at an early stage, and the number is quite large. Cough, expectoration, chest distress and chest pain are symptoms of the whole course of lung cancer, and are almost manifestations of many respiratory diseases. If the age of more than 30 years old, but also shortness of breath, sputum with blood or cough, shoulder back pain, unexplained hoarseness, weight loss, often low fever, anemia, etc., should think of lung cancer.

If you endure all kinds of symptoms, develop to emaciation "big bones withered, big meat depression, chest full of gas, breathing inconvenience" and other "cachexia" appearance appears, and then the effect of treatment is worrying; for secondary lung cancer, we must seize the "precancerous lesions" critical moment, active and systematic treatment, most of which can be reversed. Many lung diseases may turn into lung cancer in the later stage, but there are also some lung diseases that are very easy to turn into lung cancer.

Lung anatomy

For example, pulmonary sarcoidosis is one of them. This disease is also more common in people over the age of 30 or 40. It also has a familial tendency to develop pulmonary sarcoidosis and is more likely to transform into lung cancer. Therefore, for people with obvious incentives such as ethnicity, spiral CT screening should be performed at least once a year to prevent and treat sarcoidosis in time and block the path of transformation into lung cancer.
