Hi there welcome and good luck! You're sisyer's been through a lot and sounds like a strong woman - stage 1-4 is scary no matter what - as long as she maintains the strength of mind and body to fight it she will get through it with your loving support! Rads is daunting but doable! It sounds to me like she's not doing any surgical treatment. I guess that depends on staging and location. Tell her to eat as healthfully as possible, and take care!! Hugs! And sorry you have to be here!
