So sorry to here about your loss too!
Cancer is bad, I lost my mom just before Christmas 2011, day before her 68th birthday her will to go on was no more and she slept into the big sleep.
She also lost her voice, we all thought it was due to some other stuff, but when the doctor called my dad the last evening and saying he was afraid she was going to die, all I could do was calling and saying how much I love her and that I wanted her to do what she though was the best for her, sadly it was leaving us behind but I don't blame her, just did not expect that as I was hoping to see her but was not able to go home that fast.
It was at least a gift from her that we as a family for the first time in my memory had a great Christmas eve together, all the close, me, my younger sister and older brother and our dad, first time ever we all was together - thanks mom for that present!
Cherish the memories and good times, we never know when they are all we have, so many lost in battle with cancer, breast, brain, lung, some place I even don't know the English name for, those was hunting me mom, last unknown took her, so I feel your pain!!
My best wishes to you and your family!!
