Eating more broccoli, cabbage, and similar veggies is linked to a small but noticeable drop in the chance of getting any kind of cancer, especially when people eat them regularly compared to rarely.
Scientific Claim
Higher intake of cruciferous vegetables is associated with a 9% lower risk of total cancer per 100 g/day increase, with the strongest association observed in high vs. low intake comparisons, suggesting specific plant foods may modestly reduce cancer risk.
Original Statement
“For total cancer, the summary RR per 200 g/day was 0.97 (95% CI: 0.95–0.99)... Inverse associations were observed between the intake of green-yellow vegetables and cruciferous vegetables and total cancer risk... Per 100 g/d, RR for cruciferous vegetables was 0.91 (0.82–1.02).”

This big study found that people who eat more cruciferous veggies like broccoli and cabbage tend to have a lower risk of getting cancer, which matches the claim that these veggies help reduce cancer risk.
