Adenocarcinoma depends on the site of occurrence and the stage to decide whether it can be cured. Adenocarcinoma is more commonly seen in lung cancer, digestive tract tumors and breast cancer, all of which fall within the scope of adenocarcinoma. Whether adenocarcinoma can be cured or not depends on whether it is early stage or not. If the adenocarcinoma is early, it can be cured by radical surgery, such as early stage lung cancer, early stage breast cancer, early stage colon cancer, etc. Through radical surgery and systematic lymph node dissection, the 5-year survival rate after surgery is over 60%-90%, and long-term survival is possible. However, there is still a risk of tumor recurrence, so dynamic and regular follow-up is needed after surgery, and the main purpose of follow-up is to detect recurrence at an early stage.
