Not much has changed. We have no new information on what's in her brain, but we don't expect to know until Monday when pathology comes back. They did wake her up from sedation around 2:00. She's been very sleepy and clingy, as expected. The immediate concern is the pressure in her head. Without being invasive, the best way to determine how that's going is by neurological checks every 30 minutes. As long as she's acting normal (as normal as can be in the situation), and her eyes behave correctly to light, they assume there is no massive pressure issue.
Please continue to pray for her and for her doctors. No one knows what this thing is, or how dangerous it is. They've confirmed it IS tissue that was removed from the biopsy (rather than pus, like from an infection). Best case scenario might be some sort of unusual inflammation, but since infection has been ruled out, tumors and cancer are a high possibility.
