I've suffered with external piles for a number of years and they've not really bothered me apart from when I was pregnant. I've had a few episodes where I've bled after a bowel movement which sets my anxiety off. Last week I had a bit of blood when I wiped then it went away then on Monday I was wiping, the first few wipes there was no blood but then I did get some. Now I'm worried as I have had anxiety about bowel cancer in the past. Would it come and go if it was sinister? I'm 34 so relatively young but can't help but worry
