Sorry to hear about your diagnosis Longbord! Fear not though! I went thru the tumor in the head issue back in 1990-91? They removed a tumor from the area behind my ear, and it turned out to be benign, which of course made me happy! So I'll pray that in your case too, they find it to be benign, sew you up and you can keep on getting it on!
My prayers are with you for successful surgery and full recovery! God Bless!
