Whether an 82-year-old man needs to undergo puncture biopsy for lung cancer should be determined by the specific conditions of the old man, such as the size and location of the lung lesion and the patient’s health condition. First of all, the size of lung lesion and its location. Generally speaking, the larger the lung lesion site is, the easier it is to puncture, meanwhile, the closer the lung lesion is to the periphery, the easier it is to puncture, while lesions close to the hilum are at a higher risk of puncture. Therefore, before puncture, it is necessary to have a professional physician combined with imaging to determine whether the patient is suitable for puncture. Secondly: it is also based on whether the patient’s coagulation function is abnormal, and coagulation function is abnormal contraindication to puncture. In addition, the 82-year-old old man is older, if the old man’s cardiopulmonary function is poor, then it is easy to cause pneumothorax in the process of lung puncture, and at this time the physician usually does not recommend the old man to carry out puncture biopsy. To summarize, whether an 82-year-old man should undergo puncture biopsy for lung cancer is to be considered with a combination of factors.
