I'm so sorry, no words are good enough at this time of great sadness. You sound so caring of your brother and his wife. My sister has just been told she has a lobula lesion and is waiting test results, we are terrified of bad news.
I am so sorry for you all it is not fair that good people suffer like this. I am a nurse and visit people who are dieing at home I work nights at the moment and see young people ill from cancer, it breaks my heart especially when they have young children.
God Blesss you all and I hope your sister in Law can find peace and your brother strenght to carry on with such a caring sister.....
