I'm really concered about my grandfather who is 65 and was diagnosed with bladder cancer at the start of September. He went in for an operation to attempt to remove the two tumors on his bladder in mid September. Once he had healed, they have asked him back in for MRI scans and CT scans and have said that the cancer has spread to a tube towards his kidney. They have also said the smaller of the two tumors on his bladder is a very fast acting cancer and he needs to come back in for an operation to shave off some more of the small tumor and then have a second blast of chemo. They have said the operation will not be for another 6 weeks. I'm really concerned at the time this will take for him to have the second operation as they have said it's a very fast acting, fast growing tumor. Am I right to be concerned?
