I recently visited my GP as I was experiencing rectal bleeding, (red blood) stomach pains and cramps and losing weight without trying. 

I was referred for a QFit test which came back positive (32ug/g) which is high compared to the normal range of below 10. I then waited for my calprotectin which has come back as 132 ug/g. The GP says they want to retest within 4 weeks but a colonoscopy is the route they want to go down anyway due to the QFit results. All my bloods were normal. On examination by the GP they did notice a large anal skin tag. 

I am only 23 but there is a history of bowel cancer from my grandad and I am filled with worry and dread of what they may be.
