I am SO sorry to hear about the cancer. My mother passed in February 2008 from cancer. She fought til the very end because of her kids, grandkids and great grandson. She wanted us to have more time with her.
It was the hardest thing for her to go through and for us, too. Remember to take care of yourself along the journey.

She CAN beat this. It will take a lot of hard work and I hope she doesn't just give up. Remind her that you are there for her and will help her.

Sending you and her warm, safe hugs!
