Reducing Renal Cell Carcinoma Risk

Micronutrient linked to 39% risk reduction

A diet rich in the antioxidant lycopene is associated with a decreased risk of renal cell carcinoma (RCC), according to a dietary analysis of 96,196 postmenopausal women in the Women’s Health Initiative (WHI).

Investigators studied 7 micronutrients as reported on the WHI food intake questionnaire—α-carotene, β-carotene, β-cryptoxanthin, lutein plus zeaxanthin, lycopene, vitamin C, and vitamin E—and found an inverse association between RCC risk and dietary lycopene.

Women in the highest quartile of lycopene intake had a 39% lower risk compared to those in the lowest quartile. No other micronutrient studied was significantly associated with RCC risk.
