Lung adenocarcinoma is not as serious as small cell lung cancer in terms of pathologic type, but it also depends on the staging.
Lung adenocarcinoma is a type of non-small cell lung cancer, its malignant degree is lower compared with small cell lung cancer, but the specific severity needs to be determined by the patient’s stage and differentiation.
Low differentiated lung adenocarcinoma has a greater difference between cell morphology and normal tissues, and has a higher degree of malignancy, so the treatment effect is not very good and the survival cycle of most patients is not very long; while high differentiated lung adenocarcinoma has a lower degree of malignancy, a higher cure rate, and a longer survival cycle.
In addition, early stage lung adenocarcinoma has not metastasized and proliferated, so the condition is not very serious and timely surgery can be performed to recover; while patients with middle and late stage lung adenocarcinoma are accompanied by metastasis to lymphatic and distal organs, which makes the condition more serious and the cure rate is also lower.
