PRP,
Although I DO NOT know you, eversince you told me it is 'very
likely cancer', my thoughts keeps going to you daily...
All I can say is, yes you should pray (I pray for you too), and all
that the rest here have suggested also work to help you pull
through.
It is easier for me to say, I know, but it is IMPORTANT tha you
keep your spirits up and remain as POSITIVE as possible...
I wish you Godspeed, get well with his grace...
