Cyber support coming your way .. if I can recommend a couple of books, you might consider "The Breast Book" and the newer one Deanna Favre wrote about her cancer journey. Lost my MIL right after we got married to breast cancer, and have seen several work through it. Thankfully, things have come a long, long way. I won't lie, the treatment is brutal, but your mom has great odds with today's advancements. And she has YOU watching out for her, which is wonderful. Godspeed!
