Has anyone used Phesgo for HER2+ breast cancer?

I have hormone-positive, HER2-positive breast cancer that has recurred. My medical team is discussing Phesgo (pertuzumab, trastuzumab, and hyaluronidase) as part of my treatment plan. This combination targets the HER2 proteins that help cancer cells grow. I'm learning about potential side effects like fatigue, nausea, hair loss, and increased infection risk, and that my team will monitor my blood counts closely. I'd love to connect with others who have a similar diagnosis and hear about your experiences. • If you've used Phesgo or similar HER2-targeted treatments, what helped you manage day-to-day life during treatment? • What do you wish you had known before starting this type of therapy?

How can I treat nasal dryness and scabbing from chemo?

How does everyone deal with the dryness and scabbing inside the nose? My oncologist says it’s the chemo drying me out and recommended Vaseline or aquaphor, applied with a Q-Tip, but I also have pretty severe seasonal and environmental allergies. I take multiple different allergy meds and have been for years, way before starting chemo. Now I am dealing with tons of tiny whiteheads inside my nose and it’s so tender and painful. I haven’t found anything yet that won’t cause the white heads but still moisturize enough to not be in tears just from lightly dabbing my nose with a super soft tissue. It’s honestly PAINFUL. Any advice is appreciated!

What's it like taking Verzenio for metastatic breast cancer?

I have hormone-positive, HER2-positive metastatic breast cancer and my care team mentioned Verzenio (abemaciclib) as a potential treatment option. From what I understand, it's a CDK4/6 inhibitor that works with hormone therapy and is often used as a first-line treatment for cases like mine. I've heard that diarrhea can be a common side effect, especially in the first month. I'd love to connect with others who have experience with this treatment combination and hear how it's been for you. • What was your day-to-day experience like on Verzenio, especially during those first few weeks? • Do you have any practical tips that helped you manage side effects or adjust to the treatment routine?
