Thanks for your response. Although we are in different situations, it sounds as if we are facing similar decisions re: MRI. My long-term hope is that if gadolinium is problematic, another contrast agent will be found that is not. Meantime, I'm uneasy about how to monitor for a recurrence of the lobular cancer, or a new lobular tumor in the other breast. I may start a thread here to see what others with invasive lobular carcinoma have done.
