High crp since 3 reports. Colon cancer?

Hi doctor, I am under treatment of IBS since 2 month and taking antaacid, probiotic and colospa tablet since 2 month. Symtoms has improved and frequency of motion pass reduce to 2-3 per day ( only when eat outsiders) I did my CBC , esr , abdominal ultrasound, CRP and stool occulatl test All came normal expect crp. Crp came 12 in March , 13 in April and now 15. My doctor is suggesting me to go for colonoscopy to check any infection. I requested her that i am scared of coloscopy due to hypochondria anxities. And if my symtoms are improving and stool analysis tests are nornal...do i still need to go for coloscopy. My age is 32 and there is no history of any cancer in family yet. Could my crp high due to colon cancer ?? I have told all 100% symtoms correctly. Attaching last report copy. Please guide me correctly.
