Obesity, lipids, and Aggressive Breast Cancer: New Research & Dietary Implications
Table of Contents
New research from the huntsman cancer institute at the University of Utah reveals a critical link between lipids (fats) in the body and the growth of triple-negative breast cancer. The study suggests that obese breast cancer patients may benefit from lipid-lowering therapies, while high-fat diets like ketogenic diets could possibly be detrimental. This research, funded by the National Cancer Institute, challenges conventional wisdom and highlights the underappreciated role of lipids in cancer progression.
The Link Between Lipids and tumor Growth
Traditionally, obesity has been linked to cancer through factors like chronic inflammation and hormonal imbalances. However,this study demonstrates that lipids themselves play a direct role in accelerating tumor growth. Keren Hilgendorf, Ph.D.,a lead investigator,explains,”The key here is that people have underestimated the importance of fats and lipids in the all-encompassing term that is obesity. But our study shows that breast cancer cells are really addicted to lipids, and the abundance of lipids in patients wiht obesity is one of the reasons that breast cancer is more prevalent and more aggressive in these patients.”
Hyperlipidemia: More Than Just a Result of Obesity
Hyperlipidemia, characterized by high lipid levels in the blood, is frequently enough associated with obesity. However, the research team discovered that high lipid levels *alone* can accelerate tumor growth, even in the absence of other obesity-related markers like high glucose and insulin levels. This finding is notable because it suggests that addressing lipid levels could be a therapeutic target autonomous of overall weight loss.
“The idea is that lipids, which form the surface membrane of the cell, are like building blocks,” says Chaix. “If a cell receives the signal to proliferate and more building blocks are available, the tumor is going to grow more easily.We see that a high amount of lipids enables this proliferation.”
Ketogenic diets: A Reassessment in Cancer Therapy
Ketogenic diets, high-fat, very-low-carbohydrate diets, have gained popularity for their metabolic effects, including potential
