My niece went to the doctor yesterday and had a series of tests and there is a mass of blood vessels behind her eye, but it's not cancerous and it shouldn't affect her negatively. It will have to be monitored but as long as it doesn't hurt her, it will not be taken out. It's a major surgery if she needs it taken out and of course, that would rather be avoided.
The blood vessels will periodically bleed and that will cause the black eye she had.
We're all relieved and she was a trooper at the hospital, not afraid at all! Thanks for all the vibes and prayers, they obviously helped!
