"bladder cancer"

i was never told that I cancer even when i admitted for treatment,i only found out by mistake ,when i looked at my medical records online. I was told after the first attempt to remove the cancer that they had not got all the tumor and I would have to come in again,to me tumor does not say cancer. My first stay in hospital did not go well at all ,the second time i did not want to go in at all because of that
