Imbalances in cholesterol, particularly elevated levels of LDL (low-density lipoprotein), have a negative impact on health. Recent studies suggest that high LDL cholesterol may contribute to the development and progression of cancer, especially breast cancer.

• Link between cholesterol and cancer
  A study published in the journal Nature emphasizes that cancer cells often have an increased need for cholesterol for their growth and survival. Elevated levels of LDL cholesterol are associated with faster progression of breast cancer and a higher likelihood of metastasis.
  
  Furthermore, research indicates that high concentrations of cholesterol and its metabolites not only promote the activities of malignant cells but also inhibit the immune response against cancer cells. This means that an excess of cholesterol can weaken the body's ability to fight cancer.
  
  
• Phytosterols: Natural Allies in the Fight Against Cholesterol
  Phytosterols are plant sterols structurally similar to cholesterol. They are found in plant oils, nuts, seeds, legumes, and whole grains. Phytosterols can help lower LDL cholesterol levels in the blood by reducing its absorption in the intestines. This potential reduction in the risk of cholesterol-related cancer development.
  
  
• Influence of diet on cholesterol levels and cancer risk
  Diet plays a crucial role in regulating cholesterol levels and can influence the risk of developing cancer. Consuming foods rich in saturated fats and trans fats can increase LDL cholesterol levels, while a diet rich in unsaturated fats, fibers, and phytosterols can help lower it.​

Recommendations for reducing risk

Balanced diet: Incorporate more fruits, vegetables, whole grains, legumes, nuts, and seeds into your diet. These foods are rich in phytosterols, fibers, and healthy fats that can help lower LDL cholesterol levels.

• Limited intake of saturated and trans fats: Reduce the intake of saturated fats found in red meat and full-fat dairy products, as well as trans fats present in many processed foods.​
  
  
• Regular physical activity: Exercise can help increase HDL (high-density lipoprotein), known as good cholesterol, and reduce LDL cholesterol levels.​
  
  
• Quit smoking: Smoking can lower HDL cholesterol levels and damage blood vessels, increasing the risk of heart and cardiovascular diseases as well as cancer.​
  
  
• Moderate alcohol consumption: Excessive alcohol consumption can raise cholesterol levels and increase the risk of various types of cancer.​

Although cholesterol is essential for the normal functioning of the body, its imbalance, especially elevated levels of LDL cholesterol, may contribute to the development and progression of cancer. By adjusting diet, increasing physical activity, and adopting a healthy lifestyle, individuals can lower LDL cholesterol levels and potentially reduce the risk of cholesterol-related cancer development.
