So you don't think my concerns that someone might be exploiting that poor girl's and her family's suffering is totally invalid? There are so many people who've been hurt by cancer quacks who've not only taken tons of money, but increased their victims suffering selling false hope and dodgy therapies.
Is it really so unreasonable to ask who exactly is offering that 100% guarantee of curing the girl and what their credentials are? By giving money without checking this out first, you're not helping the family but potentially making it worse.
