Enhertu failure in HER2+ lung cancer: What next?

Hi @sboes, I was just catching up, and learning, from the discussions that you had on Connect in the Fall 2021. You indeed have a rare lung cancer.
I have the ALK mutation, which is 4-5% of non-small cell lung cancers. The inhibitor that I take will one day fail me too. Those cancer cells are just too smart.
Were you experiencing symptoms, or was the progression found on a scan?
Have you had an appointment with your oncologist yet? What are they recommending? Excuse my ignorance specific to HER2+, are there other HER2+ therapies that are used for breast cancer that may apply to lung too?
