Reduce cancer risk

What this outcome means

Cancer incidence describes how often new cancers are diagnosed in a group of people over a given stretch of time. On DoseRank it maps to a defined health outcome built from human studies on new diagnosis rates, age-adjusted incidence rates, and cancer-specific incidence ratios across populations – data sourced from open sources and specialized resources. DoseRank is not medical advice.
