I had Y90 for some pretty substantial (6 plus CM) liver tumors. Recovery was difficult with overwhelming fatigue and low grade fever every night for 11 weeks. 3 month MRI showed 98-99% of the treated tumors were dead. My Dr couldn't have been more pleased. So, recovery of the Y90 may be somewhat long and uncomfortable, the results were worth it for me. Most people do not have that long for recovery.
