My favorite doctor ever said to me “ the only good decision is an informed decision”. I only say this to encourage you to find out exactly what that nasty cancer is doing, so that at least when you make decisions you understand what it is you are doing and why. I remember feeling like I didn’t want to know, but for me that was a knee jerk reaction to something I felt I couldn’t control. Times have definitely changed as I now am an advocate for knowing all the ins and outs of the cancer and the treatments.
I wouldn’t want to not take a lifesaving medicine if it could give me a long, quality life, and I wouldn’t want to take a medicine that destroyed my quality of life and did not help me.

I understand totally. I just tend to think that "ignorance is bliss" doesn't apply to our health. If you don't have more tests, you'll worry that you should have or that something might have been found. And they could be reassuring that the problem is limited and can be dealt with. I guess my motto is that the problem with reality is that it always wins so the sooner I face it, the better my choices. I just wish we could all help you more...
