Emily you beat me to it - about getting a colonscopy. Please do it if after 50 or if you have a family history.

Spoke - Take heart with your BIL - medicine nowadays is amazing. If he still has some liver function he should be OK. Hopefully the cancer is removed and chemo will deal with the rest.

Be strong for your sister. She'll need it. Be an ear fr your BIL. He'll need to be able to speak his mind freely in the coming months in order to deal with the fear. Family and friends are powerful medicine. So is prayer. Take special care.
