What's it like having combination treatments for recurrent breast cancer?

My breast cancer has returned and spread to my armpit lymph nodes. My cancer is both hormone-positive and HER2-positive. My oncologist is discussing treatment options that combine different approaches - hormone therapy, HER2-targeted therapy, chemotherapy, and newer targeted treatments. They're working to find the best combination based on what I've had before and how my cancer has returned. I'd love to connect with others who have been through something similar and hear about your experiences. • What was it like going through combination treatments for recurrent breast cancer? • What helped you manage day-to-day life during treatment, and what do you wish you had known going in?
