Preventing cancers of the breast and colon by how we choose to live each day

In countries such as Scotland and the USA, many cancers are now caused by nutritional factors we can affect by our daily choices, including what we choose to eat, how much we choose to eat, and how much we choose to move about. Nearly half of all cancers of the breast and colon are caused by these choices.

Professor Tim Byers, Professor of Epidemiology and Associate Dean at the Colorado School of Public Health in Denver, Colorado, USA summarises what we now know about the ways in which these nutritional factors increase cancer risk, and what can be done about it by choices we can make both personally and collectively.
