The Role of Fats and Lipids in Cancer Growth

Fats and lipids are often underestimated in scientific research, especially concerning obesity and cancer. A recent study has shown that breast cancer cells heavily rely on lipids, making increased body fat a significant factor in the spread and aggressiveness of this cancer type in obese patients.

The Importance of Fats and Lipids in the Body

Fats and lipids are essential components of cell structure, forming the outer membrane. When a cell receives a signal to grow and multiply, the available fats provide the foundational structure that facilitates tumor growth. This explains why high body fat levels contribute to the acceleration of tumor growth.

Research has demonstrated that fats play a significant role in tumor growth in mice fed high-fat diets, as well as in those genetically modified to have high lipid levels without other obesity factors like elevated glucose and insulin.

The Link Between Obesity and Breast Cancer

Obesity is a known risk factor for breast cancer, as increased body fat provides a lipid-rich environment that cancer cells need to grow. Studies suggest that reducing fat levels can slow tumor growth, even when glucose and insulin levels are high.

These findings are encouraging as they open the door to new treatments targeting fat reduction in the blood, potentially slowing cancer growth. However, more research is needed to confirm these findings in humans.

Potential Effects of Dietary Regimens

Many patients seek diets to lose weight and reduce cancer risks or recurrence. Among these, the keto diet, which involves high fat and low carbohydrate intake, stands out. However, research indicates this diet may have the opposite effect, potentially increasing tumor growth due to higher body fat.

Therefore, doctors advise patients with high body mass index to consult their physicians to create a weight loss plan suitable for their health condition, paying attention to their cholesterol levels.

Conclusion

Fats and lipids play a crucial role in the growth of cancer cells, particularly in obese patients. This study highlights the need for a deeper understanding of the role of fats in tumor growth and opens the way for developing new cancer-fighting strategies by reducing body fat. Nonetheless, further research is essential to confirm these results and apply them to humans. For patients considering specific dietary regimens, consulting with doctors is vital to ensure the chosen diet is appropriate for their health condition.
