Daughter with breast cancer grade 2 invasive ductal waiting for tests Has baby.

Just reaching out to share that my 36 yr old daughter diagnosed with grade 2 invasive ductal breast cancer last week.  Just had MRI.  Waiting for staging. And treatment plan I am retired GP. She has 19’ month daughter.  And lovely GO husband. We are a supportive family but I don’t live nearby. We can stay there easily.   I have FH of breast cancer in mother and grandmother but both post menopausal.  Waiting for genetics and fertility appt.  I’ll do anything I can to help her   Also have a 32 year old daughter who is very close to her sister but also 2 hours away   In laws are nearby thankfully 

any advice from someone in similar position welcome. 
Chemotherapy likely. And tamoxifen. Triple positive
