Barbara, I've never heard of having a full-body MRI for stage 1 breast cancer. Are you sure you're not just having a breast MRI? That's more common, but controversial; MRIs pick up a lot more than mammograms, but a great percentage of what they pick up is benign. Still, you'd have to go through the biopsy process; and that's the reason they're controversial. Many women are led to believe, by the MRI results, they have more breast cancer than they actually do, and they go through the stress and surgery broughton by an MRI, only to find out it was all for nothing. Was the lymph node benign, or did it show cancer? If no cancer in the lymph node, there's almost no chance at all it's spread. If I were you, I'd get more informaton (lymph node involvement, or not?); and then ask specifically the reason for the MRI. Do you have a family history of breast cancer? Are you very young? Very small-breasted or dense-breasted? BRCA gene mutation? Any of these might call for the added protection of an MRI, but the American Cancer Society recommends against standard screening MRIs, except in special cases such as the ones I mentioned. Best of luck - PJH
