Lung cancer is divided into small cell lung cancer and non-small cell lung cancer according to histopathologic criteria such as the size and shape of cancer cells.

Among lung cancers, 80-85% are non-cell lung cancers, which are classified into adenocarcinoma (adenocarcinoma), squamous cell carcinoma, and large cell carcinoma.

The remainder, small cell lung cancer, is generally malignant.

Lung cancer refers to malignant tumors in the lungs. Primary lung cancers in which the cancer cells are formed in the tissues that make up the lungs, and metastatic (proliferative) cancer cells are formed in other organs and then transferred to the lungs through blood vessels or lymphatic vessels to proliferate.

) Can be divided into lung cancer.

Of course, there are no early symptoms, and even after a certain progress, it is difficult to diagnose a lot of colds except cough and sputum.

In addition, symptoms vary depending on where the cancer occurred.

Symptoms related to the bronchus or lungs include:

If you suspect cough, bloody phlegm or hemoptysis, shortness of breath, chest pain, hoarseness, relative venous syndrome, headache, nausea, vomiting, bone pain and fractures, lung cancer may be suspected.

Smoking is the most common way to prevent it because it occurs in smokers.

Therefore, for high-risk groups such as smokers over 55 years old and smokers over 30 years of age, it is advisable to perform low dose chest CT every year to detect lung cancer early.

Survival rates can be found in the data released in 2018 by the Korea Central Cancer Registry.

According to the data, the 5-year relative survival rate of lung cancer between 2012 and 2016 is 28.2% (male 23.7%, female 38.6%).
