Perhaps this will be helpful to you

 I don't really know what's useful to other people, but I'd like to tell you how I'm thinking about things. (I have been assured that saying "well when you think about it, people die all the time in all sorts of ways and they don't have any warning at all" isn't helpful.)

So one of the ways I move through the world is to make decisions based on a very simple decision tree, which basically goes:

What do I actually want?

    Can I get it?

        What's the best version of the thing that I can get?

            How do I do that? 

What I actually want is to not have ever had cancer. That would be much more convenient. Can I get it? No. What's the best version of the thing I can get? To get the best treatment possible that balances my quality of life with good outcomes. How do I do that? By doing what I'm doing. 

I have great doctors, I ask questions whenever I have them, I understand why they want to do the tests they want to do, and I understand what will change depending on the results of those tests. The uncertainty right now is complicated for me and for the people around me, and I respect that. It might be harder to be my partner or my parents than it is to be me right now, because right now, I still physically feel fine. And I'm making decisions about my health. They can and are doing a ton of things to help me! And also they can't really do anything. There's a lot of control that you just have to give up when you're doing this. It's not comfortable.

I don't know what the biopsy results are going to be. I don't even know when the biopsy is going to happen. I know that whatever happens, I'm going to listen to my doctors, and I'm going to make decisions that make sense for me. I continue to not be upset or afraid (I was a little bummed when I first got the news today but that quickly settled into "hey I'd be really cranky if I got chemo and that wasn't the right course for me"). 

I sometimes wonder if my repeating that I'm not upset or afraid will come across as trying too hard to convince you that I am neither upset nor afraid, but I just want you to understand that this is how I am feeling. This is where I am at. You don't have to be there. You are going to feel whatever you're feeling, and you're going to be even more powerless than me to change things! I think that's kind of great. It's very freeing to know that you're doing all the things you can do, the things you're supposed to do, and things are going to just go however they go. 

There are many wonderful things about believing that you are in control of your life and your body and your destiny. And in many ways you are, and those things are true! But sometimes you forget that you only have this time. I'm spending a lot of mine appreciating the days I'm getting with my friends and my family and my cats and this body. I think some people get kind of mad at their bodies when cancer happens but I have had a GREAT time in here. I intend to continue doing that. 

I don't think there are any bad outcomes to be had here. There's good news and complicated news and a lot of waiting and a lot of tests, and it's all just part of this very long process.
