24 year old diagnosed with bowel cancer

Hello everyone I’m Nicky I’m 24 years old, in August I was diagnosed with bowel cancer after putting my symptoms off for over a year. Luckily this was stage one, but I had a colonoscopy again the other day and they have taken two more biopsies as there was a little big it growth already so having to wait 4 weeks for these results. Any tips with dealing with stress with being under surveillance for 5 years. 

kind regards 

Nicky
