Yes you can drive. I had 30 rounds of proton radiation at UFPTI. The treatments are painless and do not affect you driving.

You may at some time in your treatments have to go to bathroom more. You can plan on this and go to bathroom when leaving treatment office. I have heard this question and so must be a concern for many.

Treatments are painless. You will have no idea you are receiving radiation treatments. Just realize that after several you may have to urninate more ofter and more ugently. Thus my solution was to urinate upon arrival and before leaving. Your oncologist/radiologist and urolgist should have briefed on the ability to drive is not affected. Good and realize millions have gone through this.
