Scared for tomorrow

My dad was dx with lung cancer last Tuesday and had ct scan last Thursday. Hospital rang yesterday and he is to go in tomorrow and see the doctor who may want to do a bronscopy :( that is all they said. I am so scared that tomorrow we will be told there is nothing they can do that it has spread to far...... My dad is taking it all in his stride or at least acting that way but he is still coughing and gets breatheless and tired :( he is still working and messing around with my daughter but you can see he is not right and it's so so scary :( this time 2 weeks ago he wasn't like this. The weird thing is I already feel like I know what's going to happen, I can see the tears and sadness and the decline in my dads health...... So scared I don't want to lose my daddy :'(
