Some patients do just casodex or flutamides, started decades ago with Dr. Labrie and Dr. Strum and the founder of Paactusa.org as a matter of fact. Ok so you are on what is called normally High Dose casodex, likely to have little heavier on side effects, can almost guarantee you to watch out for boob enlargement issue...however can be counteracted by either drugs like Femara (etc.) or light duty radiations usually 3 sessions (electron rays can be used instead of more potent rays)..this helps stop boob enlargement. This is a common side effect and especially with casodex in high dose.
The other option is let it happen or later do boob surgery reduction...my friend just did that.
So, much depends on your androgen receptors and how they react, because they can change on their own doings along the way and become refractive to some HT therapies and then doc would hopefully (wisely) switch you to another drug that could work differently. Many different pathways and receptors to influence PCa cells, this is why different drugs can be effective, timing is very important as to best results.
Books to read by Dr. Myers on diet is worthy and things written by Mark Moyad also useful. You could probably go to lower doseage of casodex after 3 months and see how it holds up...maybe test monthly. I found walkin PSA testings for $15, back in my early days of panic I did monthly tests for like over year. Best to you. Look at my stats below just for a kicks.
OH- did you say looks like last treatment?????? NO WAY....FIND another doc and opinion. Send doc to this website www.hrpca.org (proven treatments area)
