what is the type of injection used for bladder tumors?
The schedule for your treatment depends on your condition and on how you respond to thiotepa. When used for bladder cancer, thiotepa is infused (injected slowly) into your bladder through a tube or catheter once a week for 4 weeks. Avoid drinking fluids for 8 to 12 hours before your treatment. You should keep the medication in your bladder for 2 hours.
