Thanks so much for this helpful info. I see my oncologist for my first mammo post surgery etc (one year after my last mammo, MRI etc pre surgery) - Dana Farber in Boston likes to wait one full year. I'm hoping I can ultimately be on a 6 month alternating schedule with mammo and MRI. Stay tuned and please keep us posted. I think both Guardant and Signatera are wonderful "stacking" tools and hope to go that route too as like we say early detection is really all we have to play defense! xoxo
