Metabolic Health
The vegetables and whole grains you grow or buy at the farmers market directly influence the insulin and hormone pathways described here — what you eat shapes cancer risk at the molecular level.
When someone carries excess body fat, their fat tissue starts producing too much estrogen and sends out chemical signals that push cells to divide uncontrollably. High sugar and processed-food diets make things worse by spiking insulin, which acts like fertilizer for these abnormal cells. Together, these diet-driven changes silence the body's natural brakes on cell growth and ignite chronic inflammation that lets cancer take hold.
Key Findings
Aromatase enzymes in enlarged fat cells convert androgens into estradiol, directly fueling estrogen-receptor-driven cell proliferation in the uterine lining.
Hyperinsulinemia and IGF-1 signaling independently activate PI3K/AKT/mTOR and RAS/MAPK pathways, accelerating cell division while suppressing tumor-suppressive checkpoints.
Obesity shifts adipokine balance — raising pro-inflammatory leptin/JAK2-STAT3 signaling and lowering protective adiponectin/AMPK signaling — promoting epithelial-mesenchymal transition and chronic inflammation.

This review explains how excess body fat and poor diet drive endometrial cancer by disrupting hormone levels, insulin signaling, and inflammation — a convergence of metabolic failures that reprograms cells toward uncontrolled growth.

Endometrial cancer (EC) arises from a convergence of metabolic, endocrine, and inflammatory disturbances largely driven by excess adiposity and diet-induced biochemical reprogramming. This review s...
