Update: Thank you all for the good words.
(I had a CT scan prior the surgery but I had not the results.)
The result of the CT scan turned out to show only serious appendix inflammation for some time, a small poop that had stuck inside the appendix and blocked it, make it to get bigger and bigger.
The verdict suggested surgical operation and further investigation.
I sent the text only, to my gastroenterologist and although said that it seems to show no tumour, suggested a colonoscopy after 4-6 weeks for further investigation and see if there is another kind of more specific inflammation covered by the inflammation of the appendix.
I don't know what to think, I will just wait. I can't work for now so I must stay home.
Stitches will come out on Monday.
