Episode description
Story at-a-glance
- A high-fat diet makes it easier for breast cancer to spread by activating clotting cells, increasing inflammation and altering blood vessels in ways that help tumors grow
- Mice on high-fat diets had nearly five times more cancer cells in their lungs, even when their tumors were the same size as leaner mice
- A high-fat diet increased fibronectin, which acts as "molecular glue" helping cancer cells attach to blood vessels, while obesity increases inflammatory compounds that worsen this buildup
- Switching to a normal-fat diet for just seven days significantly reduced clotting activity, fibronectin buildup and the number of cancer cells lodging in the lungs
- Eliminating vegetable oils and reducing total fat intake to 30% to 40% of daily calories lowers inflammation and reduces your risk of cancer spread
