I'm sorry your mother is ailing. Cancer is such a dreadful disease. But as you know, treatments have really come a long way. And regardless the diagnosis, I would encourage a second opinion. You are right though, you do have the tools and you also have your faith that whatever the outcome, there is someone to walk by your side and carry you if needed.
Hang in there, Val!
