OT- Stepmom has breast cancer

I found out today that my stepmom has breast cancer. Was diagnosed last week with a core biopsy. She's having a lumpectomy on Monday and then 5 weeks of radiation. She said she already mourned and is past that.. but still very stressed out. Being that I work in a different radiation oncology department I know the inside scoop. I'm really worried because her MRI report said there is enhancement in the lymph node. She seems to think its this non-chilant simple surgery and then radiation.. but I know better and if the breast MRI says enhancing lymph node that is not good. So I'm worried, and worried (or know???) that it maybe very well be worse than she thinks. That means chemo too... 

I'm not an emotional eater thank god.. or I'd probably have eaten a horse by now. Just REALLY stressed out...
