Can’t predict that, but I can share what they told me about mine, and what then happened.

I was told that the tumor would be impacted quickly, and the pain would be reduced in a matter of weeks. That’s exactly what happened.

I was also told that I’d begin to feel the effects of radiation shortly thereafter. That happened too.

So it’s like a ”U” curve where you go in with discomfort, start feeling better, and then have (a different kind of) discomfort again.

Hopefully your 2nd round of discomfort won’t be as bad. And the good news is that at least that one is curative!

I had emergency surgery , found out I had cancer at hospital, didn't know what a colostomy was when told I had to have one. Thought I had hemorrhoids. But I know that uncomfortable feeling, hurt so I couldn't sit down. My iron was down too, had to stay in hospital and had blood transfusions before they could do surgery. It is hard to wait for tests for sure, try to keep
positive mindset. My tumor started shrinking during radiation, had six weeks of it , surgery was at end of 2015, and my treatments started in March of 2016, along with chemo. Hope this helped, hang in there. Best of luck

@mak70, I'm glad that you found the online support group here on Mayo Clinic Connect.

Here is a list of additional discussions related to anal cancer https://connect.mayoclinic.org/group/colorectal-cancer/?search=Anal%20cancer&index=discussions

Mak, let me see if I'm understanding your situation. You have been diagnosed with anal cancer with a mass 10cmx6mm that is very uncomfortable. Have I got that right so far? Are you currently having treatment to shrink the tumor to make surgery possible?
