Hi. This isn't really a forum post I thought I'd have to make, in all honesty, but; last night I was coming home late from work, around 12am or so. Recently moved out, so main contacts with my (divorced) parents is my facebook messenger. I turned on my wifi to message my girlfriend to let me in to the house, and saw a message from my dad and honestly nothing could have prepared me for what it said.

Long story short, last week, he had his right tonsil removed and found out that he has cancer in his neck. Since then, I've done a shift in a work and all thru that, I couldn't shake that thought. It didn't make me sad, or angry. But just...? It's a very surreal experience as, for me, cancer has been this almost fictitious consequence to smoking and drinking but now it's very real and very scary and I'm still trying to come to terms with this. He's been told that it was discovered early, and that it's very curable with chemoradiotherapy, so I'm happy in that sense. But I don't want to lose my dad. I don't know what's going on. I'm just very afraid and very confused and it's completely shaken me. 

I'm sorry for rambling, I just need to get this off my chest. Is there anything that I can read to understand his situation better and the effects of chemoradio? 

Thanks
