Well, cancer is complicated. There are types that behave like embryo cells (including one benign type which can create hair or toe nails randomly in the body).

Well, cancer is complicated. There are types that behave like embryo cells (including one benign type which can create hair or toe nails randomly in the body). The previous posters final comment is the critical one: let's hope she hasn't given herself cancer. Previous gene therapy trials were all stopped because of that risk. Current Crispr techniques (if that's what she used) aren't specific enough to avoid off target effects, those could easily cause cancer. I tend to be quite pro DIY medicine, but this still seems quite rash to me because of those risks.
