There is no clear evidence that lung segmental resection is more likely to recur than lobectomy, and it is advisable to choose the appropriate treatment with the help of your doctor. Lung segmental resection and lobectomy are generally the surgical procedures used to treat lung cancer. Lung segmental resection is a more precise removal of the lesion, with lower surgical risk and less damage to the lungs. Lobectomy is more extensive than segmental resection. Recent studies have shown that for nodules <2cm in diameter, the recurrence rate of segmental lung resection is not significantly different from that of lobectomy, and has a better five-year survival. It is recommended that patients consult with their treating doctor according to the condition of their lesions and choose the type of surgery based on the doctor's professional opinion that what is suitable for them is the best. In the postoperative period, we should also pay attention to the care of the body, quit smoking and drinking, if there is no control over life and diet after surgery, there are late nights, smoking and drinking, eating greasy and stimulating food, will also increase the recurrence rate. It is also important to follow the doctor's instructions for regular checkups to observe the body's recovery, and to consult the doctor when there is any discomfort.
