Absolutely. Here is my opinion. Percy may have seen a specialist in UK. She went as far as to suggest a private consultation at Addenbrooke's. He said, (according to Fanny) that in his expert opinion, that given Percy's travels, age, symptoms etc, he would be looking to screen for cancer, or check for benign tumour, or bacterial infections. He would have said if it was TB, Percy would be weeks/months in hospital, cancer would be much treatment. He would have said Percy would have to go private whatever the outcome and either way, private treatment is a lot of dosh. Isabelle gets outside the door and said they must return to SA where Percy would be covered healthwise and when they went back did not know which illness he had. But if a blood test was done, and there was another appointment, the TB would have been picked up or a serious bacterial infection and then they returned to SA knowing they were putting others at risk. What I do not believe is that after an initial consultation the specialist said cancer without any screening and let Percy return to SA believing that was what it was.
