Simone Giertz, the utterly wonderful nutcase of "Shitty Robots" fame, has a brain tumor the size of a golfball behind her right eye.
It is not malignant, but it is large, and requires major surgery at the end of May to remove it.
The impacts on her cognition and vision are unknown until after the surgery is complete... but they could be dramatic.
She's soldiering on, but has a month of living with the thing before her surgery can happen... I can't imagine having to wait, like that ...
