I have been having bad stomach and gut symptoms for a while now here are my symptoms..

stomach pains somtimes sharp and next to belly button
stomach cramp pains
stomach noises constantly like squelching and gargling
every now and then i lose blood when going to the toilet

I went to the doctors and had a sigmoidscopy done but they found nothing and a blood test that was normal

went back again and they have reffered me for a colonscopy.

Im terrified I have bowel cancer im 26 yr old male and theres no history of it in my family or cancer in any of my immediate relatives.I have lost about 13 lbs in the last 3 months but i have altered my diet since them although only slightly.Im juswondering does this sound like what i dread? the doctors seem unconcered it is bowel cancer although not ruling it out im finding day to day life difficult to deal with and also they have gave me nothing for my symptoms
