What are three environmental

causes of cancer?

Common environmental factors that contribute to cancer death include exposure to different chemical and physical agents (tobacco use accounts for 25–30% of cancer deaths), environmental pollutants, diet and obesity (30–35%), infections (15–20%), and radiation (both ionizing and non-ionizing, up to 10%).

As an MRC Programme Grant Holder, using newly developed techniques, Denis researched low-level alpha-radioactivity in the human body, principally in the lung and the skeleton, but more especially the accumulation of polonium- 210 in Children’s teeth and transplacental transfer of alpha- radionuclides to the fetus.

Linkage to

Natural & Built Environment Data

ALSPAC have linked to substantial exposure data relating to the natural environment (e.g. air pollution in the Bristol region, Radon exposure estimates) and the built social environment (e.g. neighborhood socio- demographic indicators, location of fast food outlets).
