Evening

im not really sure what to say or where to start. 
I lost my mum to bowel cancer 9 years ago and my dad to oesophageal cancer last summer. 
I had a colonoscopy 2 years ago after suffering with various issues. Some polyps were found but thankfully they were benign. Fast forward to now and for the last 6/7 months I’ve been having issues. Stomach cramps after going to the toilet, bleeding but it’s in the poop constantly gurgling stomach extreme fatigue and just generally feeling unwell. I did an at home fit test a month ago and it was positive I saw my gp on Friday and she examined me (I also suffer with lichen sclerosis so wanted a female dr) she could feel a nodule and asked me to do another fit test. Naturally I’m worried as like me she thinks it will be positive but at least it will get me back in the colorectal system and has noted it as high risk 2ww. It’s hard not to worry. I keep telling myself it’s haemorrhoids and everything will be fine but I’ve been using suppositories and tried cream and that hasn’t made a difference  I just want to know one way or another  bloods have come back fine (I was hoping my thyroid was out of whack) but at least that’s a positive there’s nothing ominous there
