Oncas: I believe you have to decide how you want to fight the cancer, do you want to be proactive or lay back and allow the cancer to get stronger and stronger. I'ts obvious that at some point you're going to have start HT, now or later is the only decision left.
If you haven't read Dr. Myer's book on HT now is the time to do so, it gives guys hope where a lot of other Docs. seem to think we're just running out the clock. He lays his position out for all to see. He has one other thing going that most other Docs don't he was on HT for an extended period of time so he knows the SE's first hand.
His position is to attack the cancer early and when its at its weakest point. 2+2 has always equaled 4 to me so it makes sense.
Please give the book a read, you'll feel much better about your situation.
Good luck
David
