Cancer patients may face delayed diagnoses, unnecessary treatment changes, and increased medical costs from inaccurate test results. Consumers may lose confidence in over-the-counter supplements, reducing demand in the supplement industry while increasing reliance on medical supervision.
Potential FDA regulatory action on biotin supplement labeling and warning requirements; possible restrictions on supplement marketing claims; increased clinical guidelines requiring oncologists to screen patients for supplement use; potential insurance coverage changes for supplement-related complications.
