Hi there.  So sorry to read you are going through all this. My treatment was quite similar. My last chemo was in November 2024. I had chemo and radiotherapy at the same time with brachytherapy in the middle.. as then had a different type of chemo. I haven't had any permanent bowel or bladder things but totally understand your anxiety. I am stage 3b. They are incredibly precise eith the radiotherapy..you just need to get all the drinking done so the bladder is full and put the way in the same way each day! Do hope things go well for you  x
