A 73-year-old patient was diagnosed with central lung cancer after continuous cough. The tumor has invaded blood vessels so he is not suitable for surgery. The patient refused radiotherapy and chemotherapy, so the Prof. Niu decided to performed cryoablation on him.

The treatment of central lung cancer is currently a medical quandary, and conventional treatment like surgery is off the table. Radiotherapy is an option, but it comes with many serious side effects, and many elderly and poor-bodied patients cannot bear it. For central lung cancer, cryoablation is a relatively safe option with relatively fewer side effects, can reduce the tumor burden as quickly as possible, and can also provide a better foundation for subsequent systemic treatment.
