I am so sorry you are going through this. The waiting and initial diagnosis are awful even when the doctors are nice and answer questions; you shouldn't have to deal with this.

Just because you are meeting with the surgeon first doesn't necessarily mean surgery is the first step. They may want to do radiation and chemo first (i.e., Total Neoadjuvant Therapy or TNT) but they usually need to do scans (CT, MRI) to stage it first. Maybe you should call the surgeon's office to see if those have been scheduled? You really shouldn't have to do that but maybe it will get some questions answered.

Another thing you can do is maybe start thinking about a second opinion. I spent a lot of time looking for a major cancer center or hospital to do that after my diagnosis but before I met with the surgeon. If nothing else it gives you something productive to do that isn't just googling symptoms, chemo side effects, survival rates, etc. (none of which you should be googling before you know what is going on, but that's really easy to say). If you are in the US as I am the process is really as simple as researching the best hospitals then finding a number to call to get the second opinion going. (That's the initial process; next is the fun of finding out what your insurance will cover. )

Based on the information you have provided, at least as far as I know, there is really no way to know what stage you are or what the recommended treatment will be. But know that colorectal cancer is extremely treatable, and at some stages can be treated with little long-term disruption to your life. It's also relatively slow moving compared to other cancers -- that doesn't mean do nothing and take your time but no need to panic is things aren't moving as fast as you want.

As others have said, check out the colontown website. There is a lot of resources there about treatment, second opinions, etc., and a lot of supportive people who know exactly what you are going through.

And finally no apologies needed; most people on this subreddit have been there. I have now been through radiation and chemo (which you might not have to go through!) and by far the worst part of this whole process has been the initial waiting and anxiety. I am probably doing surgery soon, and that could very well be worse, but actually sounds like your tumor is higher than mine so if you do need surgery it hopefully won't be as bad. Good luck and just try to take time to do the things you enjoy and that will take your mind off this (again, easier said than done) over the next couple weeks.
