You poor soul, you sound absolutely stressed out and terrified, worry can be so all consuming, it can make us feel ill, but I know its no use telling you not to worry as I would be the same in your situation Hoping the news tomorrow isn't as bad as you fear and you can have the polyp removed quickly. They never leave anything like polyps for long anyway, so perhaps you are being seen quickly in order to be put on the emergency list. This is quite common practice and happened a lot where I used to work. We always kept a slot at the end of each day's list for emergency but routine surgery such as yours. I have never had an MRI scan but even the thought of it gives me a racing heart, so I can empathise with you. I heard they are very noisy despite being able to listen to music !
