Cancer Epidemiology

In rural Uganda, a long-running study of 25 villages has revealed that infections are the primary cause of cancer in this population. The General Population Cohort, which has tracked the health of these communities for 30 years, shows that cancer is a major cause of death here, driven by underlying infectious agents. This matters because most cancer research focuses on high-income countries, where lifestyle and genetics dominate. In Uganda, the picture is different: infections such as viruses and bacteria trigger cancers that are potentially preventable. The research aims to map how these infections spread and how much disease they cause, with the goal of designing interventions to reduce the cancer burden. If successful, this could lead to targeted vaccination campaigns, screening programmes, or treatments that interrupt transmission. The work is fundamentally epidemiological—it does not develop new drugs or devices—but it provides the essential data needed to deploy existing tools effectively. Similar fundamental population studies have underpinned public health victories from HIV control to cervical cancer prevention.
