First off .. I would like to tell you how sorry I am you are back on this roller coaster. Hope it is just a smooth coast.
With that being said, I agree you need to get this thing out.
I was in the exact same situation as Debb. I had a "cyst" on my ovary .. the ob/gyn oncologist was certain by its appearance (being fluid filled) it was just that .. a cyst. I was your age at the time and was also told this is very typical to have these at our age. I like Debb, was booked for surgery, and before I could get there it had leaked its fluid all over my abdomen. Just like Debb, it was crc met. to ovary. I did not have hipec, but standard chemo after surgery and did recur to pelvis.
I am not trying to be negative Nelly .. just want you to be aggressive and assertive .. because colon cancer is no joke and we are all at high risk .. scans, mri, ultrasounds and medical professionals all thought mine was "just a cyst" .. all except me and my CR surgeon, that is.
As for if it is possible for slow growing crc to grow that fast .. well, in my case it was the fluid
being built up in the ovary from the constriction
of the actual tumor that made it appear to be a cyst and be growing so fast .. not the actual tumor.
I sure hope this helps.
My best to you.
