For now, things are fine. This time around, I'm going to come back in 6 months for another ultrasound. If warranted (likely), then I'll have a biopsy, but a far less invasive one than the one I went through last time around.
Basically, this one was very different from the second (and the first) and I greatly appreciated the surgeon's far more laid back, more hands off, more "wait and see" approach.
It's exhaaaausting. But now I can move on to the eleventy million other things on my to-do list, like filling out the application for my kid's summer camp (in February? yes.) and figuring out Adult Money Things, as adults do.
