colon polyps

I had a gallbladder removal in November 2010 since then I've had ongoing issues such as nausea,cramps,diarrhea and bloody stool... Surgeon sent me to a G.I and they performed a Colonoscopy on December 27, 2010... 6 polyps removed and sent to pathology.. have to wait 2 weeks for pathology.I've had moderate pain and diarrhea since. Question is.. why do I have to wait for pathology? from what I've read once they remove polyps there is no need to further test but yet the paper I received from my G.I doctor states repeat test based upon pathology. I really do not want to go thru that test again.. Please help.

This is because polyps can be cancerous and pathology will determine if they are cancerous or not which will determine if you need to have another colonoscopy.
