Japanese researchers have identified a link between a number of infectious diseases and the development of oncology over the next six years.
As part of the work, health data of more than 48 thousand people were studied, annual prevalence rates of influenza, hepatitis, gastroenteritis and pneumonia were taken into account, writes Eurekalert.
Scientists noted that cancer develops in an inflammatory environment, which is often caused by exposure to chemical carcinogens, as well as impaired immune systems.
Patients with gastric cancer were more likely than others to suffer from pneumonia, hematological cancer was often preceded by hepatitis, and testicular cancer was influenced.
However, the study had several limitations. In particular, it did not contain any information about the effects of the environment, lifestyle and genetics.
