Since writing it feels like I've been on a roller coaster ride . Godfrey healed well but now the swelling is back and larger than before , he had a scan and the vet said it was unlikely to be just fluid build up , as it looked more substantial on the scan , so either the Tumor and therefore the cancer is back or vague possibility it could be severe inflammation . However Godfrey has been on both antibiotics and an anti inflammatory . He goes back to the vets on Wednesday and they may want to take more cell samples in which case I should get the results on Friday and I'm terrified! Does any one have any idea how long a Guinea pig can live with cancer ( it is an aggressive carcinoma but on his hip) ? Currently he is perky , eating well and has even gained weight. I guess I'm just terrified of him suffering and I don't want it to get to that stage , but I also don't want to cut his life short while he's still happy . I'm so confused and I feel almost like I'm grieving for him while he's still here. Has anyone else nursed a terminally ill Guinea pig ( or other pet)? Advice would be great. Obviously I'll also discuss all this with my vet but I'd like to talk to someone whose been through a similar experience.
