My father is 58yrs old. Last November, 2017 he was diagnosed with TaG2 bladder cancer. Right now he's having ankle swelling. 5 days ago he had serum
creatinine blood test which shows 1.23,then on 12th may, he had his first check up cystoscopy which shows no recurrence in bladder.. Is it
kidney disease? Or something serious? What should I do? He takes Aldo at 50 tablet for blood pressure. Should we change that? Need advice.
