The cure rate of early primary lung cancer is high, and the five-year survival rate of early non-small cell lung cancer can be up to 75%, while the five-year survival rate of early small cell lung cancer is 45%, while the cure rate of advanced lung cancer is lower and the five-year survival rate is generally shorter.
Primary lung cancer is the cancer that originates from the lung bronchus, including many different types and different stages, and its cure rate will be affected by the type, stage and other factors.
Generally speaking, the cure rate of early-stage primary lung cancer is still relatively high, and the five-year survival rate can reach about 75% with timely radical surgery to remove the lesion area and postoperative radiotherapy and chemotherapy according to the situation.
However, advanced primary lung cancer is more difficult to treat and has a low cure rate because it is accompanied by metastases to lymphatic and distal organs, etc. The treatment is mainly to prolong the survival cycle.
