Hello Falconery and a warm welcome to the forum though sorry you have to be here. I too have PCa and had aggressive radiotherapy RT not radical, the difference being i had a much larger dose of radiation though both treatments are usually over 20 sessions but lately a higher yield over 6 sessions has become an option, Side effects for me were fatigue, hot flushes, urinary incontinence, man boobs, emotional and loss of libido. Fatigue i exercised through it in 3 months, hot flushes took meds for a couple of weeks all clear, incontinence took 4 months to get to where you could get on with life without it being a problem, man boobs not so noticeable, emotional still emotional but less so and still get tearful at times but a lot less than in the beginning, Libido 6 weeks and back to normal. As your PCa is T3b there is a good chance you may have RT to clean up the area after your prostatectomy should you choose that option. I was lucky to not get erectile dysfunction most guys get it whether through surgery or RT, the main difference being you can get it back after RT but not after surgery. One thing to mention regarding getting emotional after treatment most guys, me included liked it. take care.
