I can't tell you what to decide. I have truly learned that everyone is different. I'm living proof of that. I switched to an oncologist who would "do" something that I could understand and for which he had good reason rather than the oncologist who wanted to wait and see. It wasn't the idea that anyone was right or wrong, it was a personality thing. My personality is "type A", I'm aggressive, so the active doctor fits my personality. I feel that's important.
My experience with chemo is atypical, but my doctor said that my generally good health was a good indicator of my tolerating chemo well. That has been an understatement. My side effects have been limited to some (not complete) hair loss, injection site vein scars, and some slight blood count impacts. And my PSAhas responded very well. So, I'm the poster boy for Docetaxel but I'd never want to make the decision for anyone else. That's up to you and your doctor.
Please feel free to check out my story. I've made many posts with a day by day of my first chemo cycle. I've been through lots of stuff. And reading others stories has been helpful.
I would be so bold as to make one recommendation. Take charge of your condition and decide to do it from a positive point of view. I have seen positive people get better care and all of my care team has endorsed my positive attitude as a good thing for my condition. Every black cloud HAS a silver lining.
Keep it positive and smile :)
