Well tomorrow is surgery. My best friend did some research and has put my mind at ease a lot- the surgery he is having can only be performed in a very small number of patients and the fact they believe they will be able to do it on him further confirms it was caught very early. Which is excellent. At this stage they dont think he will need any follow up treatmenr other than regular checks which is also great.
For those interested, he is having the last type:
He has also spoken to his boss and housemates about it which im proud of him for doing, I know how much he didnt want to. He didnt go into detail, just told them he is having this surgery and needs some recovery time.
