CT Scan radiation. And took medicine.

Hi doctor, Let me tell my medical history, I had gerd and constipation frequently in year of 2020 , previously I had anal fissure suffered a lot then got recovered by 2017 , I was suffered by it from 2011. After repeated constipation our ask to take ct with in year 2022 , so the report said chances of wall thickening with ibd disorder recommended for colonoscopy and Endoscopy, both the results are normal not even small infection there by gods grace . Then doctor suggested me to take only pure vegetarian food since my father had pancreatic cancer at year of 2011 and we undergo surgery and chemo  , then he was late passed away by 2013. Even I was getting fear taking multiple test further even small stomach issues. Fear is whether I am getting cancer. Even I was tempted eat chicken one day it creates stomach problem again and I went to doctor, force him to take colonoscopy and endoscopy. That results are fine only endoscopy they recommend for errosive gastrities and took medicine.
