What are the risks of someone having cysts drained from their lungs that has aids

My brother has aids. he has to have some cysts drained from his left lung. are there any risks or concerns with him having this procedure done?

There are risks associated with every medical procedure, and each body responds in it's own way. You'd get a more accurate answer by talking to the doctor responsible for your brother's care since he is more knowledgeable about your brother's specifics. I hope all goes well.
