We only received a brief message about the MRI, since Dr MacDonald was booked with clinic appointments and unable to meet with us this morning at the proton center, but the cyst is "stable, if not smaller."
In my mind, that could mean a couple of things. It could be that the cyst expansion we saw before inflated it enough that the catheter is now able to continuously drain it, or the radiation is already working. Either way, it's good news. We just don't want to see it get any bigger.
I think this means Summer won't have to have another MRI here in Boston, but we'll see what Dr MacDonald says when we see her next.
