Hi--I'm glad you found Mayo Connect. I hope you get some useful comments here. I'm just a bit younger than your mom, with breast cancer that is predicted to spread. Can you talk to your mom about what she wants? The basic decision is hers--although I'm making all my decisions in conjunction with my daughter, husband, and best friend. Your mom is so lucky to have you! I think that you need to let her talk openly about her feelings and decision making process. What does her oncologist suggest? You have clearly noted the two main options. But she could consider chemo, and then eventually go on to just management. Is she generally healthy, or have other conditions? Anyway, ask her what she wants--and find out how much input she needs from you...I'm guessing she'd like your opinions too. Wishing you both peace and strength--and just saying again it is great how you care about your mom.
