What's it like after CDK4/6 inhibitors for stage IV breast cancer?

I have hormone receptor-positive, stage IV breast cancer with bone metastases. I've already been through treatment with Ibrance (palbociclib) and Kisqali (ribociclib), so I'm now looking at third-line therapy options or beyond. My oncologist mentioned several possible treatment paths, including chemotherapy with targeted therapies, hormone therapy with newer targeted drugs, or chemotherapy alone - all with bone-strengthening medications for the bone metastases. I'd love to connect with others who have a similar diagnosis and treatment history. Your experiences and any day-to-day tips would mean a lot to me. • What has your experience been like with third-line treatments after CDK4/6 inhibitors? • What helped you navigate the different treatment combinations available at this stage?
