We only know what Tiffany wants us to know. I highly doubt her medical team is inept and that things played out exactly as she describes. She, Amma, and Matt are clearly naive, afraid to hear the truth, and don't ask the necessary questions. My god, she and Amma just speculated that the reason they couldnt perform the biopsy is that the tumor is gone!!! They are living in la la land. How can 1 patient leave EVERY medical appt for the last year so confused? Its simply not possible! Tiffany is either refusing to listen, believing only what she wants to believe or else deliberately misleading her subs to increase viewership and profits. Probably a combination of all three.
