According to this article her sister already had 3 surgeries but still needs additional treatment.
According to Russian publications she had surgeries in Germany, and financial question was very serious. Tarasova helped to find a sponsor.
Actually, I too feel somewhat uncomfortable with the discussion of Adelina's family matters so openly. Especially in the context of "she needed prize money to pay for her sister's treatment."
wont be long before the Yuna bots too start trashing Adelina's sister's condition
that would be a new historic low in FS bot fanaticism
I think this is a private matter with medical conditions
should not be discussed here. hope the mods close it
