Several common chronic diseases together account for more than a fifth of new cancer cases and more than a third of cancer deaths| BMJ | via ScienceDaily
Findings from research published in the BMJ show that the cancer risks from common chronic diseases, such as heart disease and diabetes, are as important as those from five major lifestyle factors combined.
A team of researchers investigated the combined effect of eight common chronic diseases or disease markers on cancer risk compared with lifestyle factors. Among the conditions evaluated were cardiovascular disease, diabetes, chronic kidney disease, pulmonary disease, and gouty arthritis.
The researchers found that cardiovascular disease markers, diabetes, chronic kidney disease markers, pulmonary disease, and gouty arthritis marker were individually associated with risk of developing cancer or cancer death.
Together, these chronic diseases and markers accounted for more than one fifth of all new cancers and more than one third of all cancer deaths in this study population, which was similar to the contribution of five major lifestyle risk factors combined — smoking, insufficient physical activity, insufficient fruit and vegetable intake, alcohol consumption, and obesity.
The researchers also found that physical activity was associated with a nearly 40% reduction in the excess risks of cancer and cancer death associated with chronic diseases and markers.
However, the authors point out that chronic diseases are not targeted in current cancer prevention strategies — and say their findings have important implications for developing new strategies that target chronic diseases.
