Hi there ...

Not sure from your post if he has cancer or just going to find out ...

He is probly going through those " what ifs" and I remember that time to well .. for me the scariest part is waiting to find out ... there's lots of factors like age, health and stuff ... I needed time on my own, to cuss cry and take it all in ... till I felt strong enough to let my loved ones in ... I'm so glad they gave me that space ... but when I was ready they supported every decision I made .. it was my cancer and l needed to go down whatever path I chose .. though I did listen to them but it was down to me .. 

If he's not had a diagnoses then he just may be o.k ... 8 out of ten are usually benign... so hold on till he knows what he's dealing with ... try to give him space while telling him your there for whenever he needs you .. just hold his hand and once he gets all the facts he may think differently ..

I've been on both sides of cancer... and I think it's far harder seeing someone you love go through it .. but hold on in there .. and you can let those thoughts loose on here, there's lots that have been where you are now ... fingers crossed for good result ... Chrissie.....
