A groundbreaking study funded by the World Cancer Research Fund reveals that obesity during adulthood significantly reduces survival chances for breast and colorectal cancer patients. The more severe the obesity and the longer it persists, the lower the odds of survival post-diagnosis—reinforcing the vital role of weight prevention.
For women, the duration of obesity from ages 20 to 50, combined with its severity, directly affects survival after a breast or colorectal cancer diagnosis. Each additional year of excess weight further diminishes these chances.
These results underscore the long-term impact of obesity on cancer outcomes. Previously known for elevating the risk of developing breast and colorectal cancers, obesity now proven to increase mortality risk even after diagnosis.
The World Cancer Research Fund recommends: "Stay at a healthy weight. Keep your weight within healthy limits and prevent weight gain in adulthood." While further research is needed on post-diagnosis weight management, this study highlights obesity's profound effects on cancer survival.
