I had a colonoscopy a few weeks ago due to a positive FIT test and change in bowl movements and bad belly pains.

They found quiet a few Polyps managed to remove 5 and 8 random biopsys but because of the pain I had to stop.

one was 15mm they cut it off but then they dropped it. They ask me to look out for it in my poo but I couldn't see it.
so that one never got tested and I dnt know if it is still inside me. Is that a problem? 
it was graded IP, pit type IV through images she said and the rest were 6mm IIa pit type IIIs

i get the pathology results on Friday and the fact that it's been over 4 weeks i am taking that as good news but Im concerned about the one they left floating around inside me.
They told me they want to do another colonoscopy in 6 months time because they need to remove the rest of the polyps But 6 months seems so long away. 
Not sure if this is related but I had bloods done last Friday at 3pm my doctor called me at 6pm to say that my white blood cells have been rising over last few months so i on 2 week referral to haematology now to. 

just wondering what people thinking
