A girl 6 years old, retinoblastoma.
Eye removal was planned, however a Swiss clinic promised it's not mandatory and eye can be saved. Distant healing started somewhat later.
Medical examination results were only positive, with one episode of relapse though, which was quickly cured by surgery, and since then no problems - the latest update of 06.06.2017 allowed med. staff to schedule next examination in 6 months - which is quite lengthy, considering how fast and unexpectedly this tumor recurs.
Retinoblastoma has probably the highest cure rate of 93% of all cancers, also due to early detection in most cases.
There's no statistics though, on how frequently eye removal is done, so every effort is to be made to preserve a functional eye.
