Obesity is more than a weight issue—it’s a major cancer risk factor. Scientific research confirms that excess body fat influences hormonal, inflammatory, and immune processes that can trigger cancer. Here’s how: Key Mechanisms Linking Obesity to Cancer: Estrogen Overload: Fat cells produce extra estrogen, especially after menopause, increasing the risk for breast, ovarian, and endometrial cancers. Insulin and IGF-1 Elevation: Obesity leads to insulin resistance and higher levels of insulin and insulin-like growth factor 1 (IGF-1). These stimulate abnormal cell growth, increasing the risk of colorectal, prostate, kidney, and endometrial cancers. Chronic Inflammation: Fat tissue generates low-grade inflammation, damaging DNA and encouraging tumor formation—particularly in liver and biliary tract cancers. Adipokine Imbalance: Obesity alters fat-derived hormones like leptin (which promotes cancer cell growth) and reduces adiponectin (which usually protects against cancer). Weakened Immun...
