Colonoscopy

Hi All my husband had colonoscopy after positive FIT Sunday and consultant took him and I into side room and mentioned diverticulitis and a polyp taken biopsy and the area of concern bottom of rectum an ulcer type swelling. Images and biopsies taken. Told us MRI and CT to be done asap to rule out anything else. Very worrying. Mentioned needs to be removed whatever it is after meeting of the results. 2 week wait for biopsy results. Is all this normal the C word wasn’t mentioned just area of concern. 
thanks
