Below you can see the associations observed in two large European cohort studies, i.e., "EPIC" and "UK Biobank".
"In these two large cohorts, higher BMI [body mass index] was associated with an increased risk of obesity-related cancer among European adults irrespective of their CMD [cardiometabolic disease] status. However, the joint exposure to overweight/obesity and CVD [cardiovascular disease] may be associated with a higher risk of overall and obesity-related cancer than the sum of the separate associations of the two exposures. These findings suggest that obesity prevention in population groups with CVD would lead to a greater reduction in cancer incidence as compared to the general population." Fontvieille et al. 2024
