Surgery removed ALL the cancer cells. You are being paranoid, and you are going to be just fine.
I have transitional cell carcinoma showed up cancer in the bladder as grade 2 stage0 was removed will this kill the bad cells
All cancer is of the cells. The surgery you had removed tissue that contained cancerous cells. Unfortunately, there is not absolute answer about recurrence of cancer. There could still be cancerous cells remaining now that were not removed by surgery that would continue to divide and multiply. Or at some point in the future, normal cells could again mutate and become cancerous. Or you could remain cancer free for the rest of your life. Have you discussed this with your oncologist and any follow up treatment (e.g. chemotherapy, radiation, etc.).
