Hi @kimw71,
Lots of good advice already so I will just say that you sound a very positive person who will be able to cope. Take it one step at a time and trust your oncology team.
Don't worry too much at the moment about your friend response, they may be in shock too and just not sure what to say. True friends will come back, and you will have many more here for support. Cancer is a tough diagnosis and it takes a while to get your head around it for everyone. As Arpie suggested listen to the Dr Charlotte Tottman's podcasts, they are really helpful and can put your mind at ease.
Wishing you all the best for your upcoming surgery, and try not to stress too much until you at least know what you are dealing with. :-)
Take care, R.
