I don't have experience with lung tumors in guinea pigs. But I can tell you that it's very likely inoperable. Lung surgery is very hard even on humans, and guinea pigs don't tolerate lengthy anesthesia anywhere near as well as humans do. When you add the necessary broken ribs to get to a lung tumor, the inability to keep a pig still for a suction drain to work, and the necessity of force feeding after such a surgery, it's just insurmountable, IMO. As harsh as it may sound, if it is a tumor, the kindest thing to do would be to keep her comfortable as long as you can, and let her go when it's no longer possible.
This needs to go on your pig's medical thread. I'll move it over there.
