It's always tough seeing a parent or child with an illness like that.
well, every single person on Earth is either a parent or a child, so I guess that about covers it
this is tough news no matter who it affects. it sounds like her mother didn't catch it until very late, but it's not like it would be any less tough if it was discovered early. cancer is a terribly unpredictable disease that isn't biased and doesn't play by the rules.
I wish her mother the best of luck, but more so I'm worried for the family. cancer treatment can be so expensive on top of how much energy it takes out of those who care for the person receiving it. regardless of the outcome, hope can be found in strength. from what I know about Rachel, she has got strength in spades and she had to get it from somewhere. I wish you and your family the best.
