Excess weight (overweight or obesity) and lack of sufficient physical activity are associated with increased incidence of several cancers, including adenocarcinoma of the esophagus, colon and rectum, kidney, pancreas, postmenopausal female breast, and endometrial cancer.
Maintain a healthy weight and engage in at least 150 minutes of moderate-intensity aerobic activity per week. This is not just about appearance; it is a primary defense against several types of cancer, including breast, colon, kidney, and pancreatic cancers. The risk increases significantly with higher BMI and lower activity levels.
A rigorous review of more than 7000 studies on the relation between nutrition, physical activity, excess weight, and cancer risk concluded that there is convincing evidence of an association between excess weight and increased risk of several cancers, including adenocarcinoma of the esophagus, colon and rectum cancer, kidney cancer, pancreas cancer, postmenopausal female breast cancer, and endometrial cancer.
Why this rating
Based on a rigorous review of more than 7000 studies and comprehensive meta-analyses, establishing 'convincing evidence' per IARC standards.
