In the minds of most of us, elderly people who are above 80 years old should not consider surgery if they have tumor, for one reason, they are too old to suffer the pain and torture caused by surgery, and for another reason, they think they are too old to live as long as they can. In fact, this should be handled in different situations. Nowadays, although many people are 80 years old, but their physical condition is still like 60-70 years old, if such patients have tumor and the tumor belongs to the scope of resectable surgery, they can consider surgery, and the effect of surgery for such patients is usually better. However, because the function of the organs of the elderly is poorer than that of the young people, more pulmonary and cardiac complications occur after surgery, so compared with other patients, such patients need more careful care during the perioperative period.
