We had the oncologist appointment today. They couldn't get anything fully conclusive about the type of cancer, at least not without doing a biopsy which is a bit risky itself, but he's going to go on chemo next week once his UTI is under control.
The prognosis for the specific type of cancer that it most likely is is an average of six months, but there's no way to know how well he'll respond to treatment so it might be more, it might be less. 😞
