I don't think this is the case for antioxidants across the board. Peter Langjoen, who has pioneered CoQ10 research and used it extensively clinically addressed coQ10 use with chemotherapy in this interview and reluctancy of cancer centers to allow patients to use it: https://youtu.be/9Z7X9WPWv4Y?si=avOV0u4ruy_zNslr&t=746.

While coenzyme Q10 may show indirect anticancer activity through its effect(s) on the immune system, there is evidence to suggest that analogs of this compound can suppress cancer growth directly[1].
