The severity of adenocarcinoma lobes removed needs to be judged according to the part of the lung lobes removed, if the right upper or right middle lobe is removed it is usually not serious, if the left upper or left lower lobe is removed it is relatively more serious. There are five lobes in the lungs: the upper, middle and lower lobes of the right lung, and the upper and lower lobes of the left lung. The upper and middle lobes of the right lung are usually smaller in size, and their removal usually has little effect on lung function. Under normal circumstances, normal lung function can be restored relatively quickly after surgery with appropriate postoperative adjuvant therapy and rehabilitation exercises. The upper and lower lobes of the left lung are relatively large in size and are located on the left side of the chest cavity closer to the heart, so the recovery time after resection of the upper or lower lobes of the left lung is relatively longer, and blood flow to the heart may be slowed down due to the decrease in ventilation. Therefore, the removal of the upper or lower lobe of the left lung is relatively more serious. Lung lobectomy patients should quit smoking and drinking, meanwhile ensure sufficient rest, proper breathing exercise for lungs, and avoid going to dusty environment so as not to stimulate and aggravate the condition. In addition, the severity of adenocarcinoma lobectomy is also related to the patient’s own recovery, and it is recommended that the patient should consult the doctor for examination in time, and the specific results should be based on the doctor’s advice.
