Abstract
- Dietary iron intake and body iron stores have been suggested to increase cancer risk, especially colorectal cancer. Within a population-based case-control study in Stockholm county 1993-94, information on dietary and supplementary iron intake were collected through a food frequency questionnaire. An initially noted positive association between intake of supplementary iron and colorectal cancer risk was reversed when intake 5 years prior to cancer diagnosis was subtracted. Reversed causality due to early disease giving symptoms of iron shortage, resulting in iron supplementation, is an issue to consider when a possible association between intake of iron and cancer risk is investigated.
