Cancer Epidemiology

Population studies for cancer incidence, screening and early testing

Next Project

CCDC’s CARRS population-based cohort data were utilized for investigating factors for cancer incidence, screening and early testing. CARRS cohorts are urban cohorts of the ‘Centre for Cardiometabolic Risk Reduction in South Asia’ . The Indian cohorts are in New Delhi and Chennai (read here: https://pubmed.ncbi.nlm.nih.gov/35138386/).  Previously, this population was linked to cancer registry or other methods to affirm cancer diagnosis (read here: https://pubmed.ncbi.nlm.nih.gov/36878651/ ).

PROJECT EXECUTION

Collaboration on pooling of cohort data across different regions of the world to study the association of vegetarian diet and cancer incidence (2020-2023)

CARRS cohort population was a part of ‘UK Oxford University’s vegetarian diet consortium’ comprising 11 prospective cohort studies from Western Europe, North America, South Asia and East Asia.

Read here: Cancer Risk in Vegetarians Consortium — Cancer Epidemiology Unit (CEU). Supported by World Cancer Research Fund awarded to Oxford CEU, this project evaluated diverse vegetarian diets across 3 continents and the association with cancer incidence.

 Determinants of breast and cervical cancer screening and early testing (2022-2023)

We utilized CARRS cohort population data and examined the prevalence of breast and cervical cancer screening or early testing among regionally representative women and investigated individual level factors associated with the uptake of recommended screening or testing in this population. This was part of a mentorship program led by Polygeia Student-led Global Health Think Tank, Global Health | Polygeia | Thinktank to empower students and graduates to research and write on global health issues.

IMPACT

In addition to academic journal publications, we trained a group of medical and public health students across 4 global institutions (Imperial college, London; University of Cambridge; London School of Hygiene and Tropical Medicine; and Royal College of Surgeons in Ireland) in the concepts of cancer screening and early testing, social determinants, and quantitative analytic methods.
