Hello @donnabl I am so glad you are going to get that tumor treated. I was treated with ablation but considered for Y90 before that was decided. There is lots of info on Y90. Here are some links from Mayo. https://www.mayoclinichealthsystem.org/hometown-health/speaking-of-health/targeted-radiation-therapy

Wishing you the best results and assuring you that you are getting top notch quality care at Mayo.
