Could you tell me what Y-90 is? I had a bowel cancer op in Nov 2022, liver cancer op in Aug 2024 and have now been diagnosed with stage 4 lung cancer but remain very fit - just completed a 300 mile bike ride over a week in France (albeit on an e-bike!). A scan at the end of August and a meeting with my oncologist will determine what happens next and so it will be useful to know about Y-90. I'm aged 80.5. Thanks for your advice.
