Fit test 400

Hi. I'm 30 years old and my doctors just told me my Fit test has come back at 400, and that the stool samples I did are also extremely high.

I've been reffered on a two week wait pathway but the letter I've received for my appointment says "urgent referral, suspected cancer" and of course I am absolutely terrified! I've got a telephone appointment first then I presume they will do a colonoscopy?

My doctor said she thinks Ulcerative Colitis or Crohns but she can't rule cancer. I'm so scared!
