Several studies have recently shown antioxidants can promote metastasis in cancer.
The complete study is behind a paywall which for me, leaves some questions unanswered. If anyone has access to the full version, it would be helpful.
While the title mentions the use of pro oxidents may be beneficial against cancer, from what I can find it looks like this is only inferred from the study. I also could not get a sense if antioxidants in food would have the same effect as supplements. Supplements are an easier way to consume higher doses of antioxidants as well as metabolized differently. But does that make a difference?
Unfortunately, cancer cells start developing before it's discovered and some of these people may be taking high doses of antioxidant supplements.

This study is limited by the fact that this research was done on mice. However, because of the results of this study as well as previous research with similar findings, I would think a study with humans would now be considered unethical. See below. Bolding is mine.The study, researchers said, echoes some other study results showing cancer patients' tumors actually grew while being treated with antioxidants

"Some of those trials had to be stopped because the patients getting the antioxidants were dying faster. Our data suggest the reason for this: cancer cells benefit more from antioxidants than normal cells do."
