Statins may reduce breast cancer mortality rates - Study reveals

A new study found Statins may reduce breast cancer mortality rates -Statins are a class of cholesterol-lowering medications that work by blocking an enzyme called HMG-CoA reductase, which is responsible for the production of cholesterol in the liver. Statins are one of the most commonly prescribed medications in the world, and they are very effective at lowering both LDL (bad) cholesterol and total cholesterol levels.

Statins are used to:

  • Lower cholesterol levels: Statins are the most effective medications for lowering LDL (bad) cholesterol levels. They can lower LDL cholesterol by up to 50%.
  • Reduce the risk of heart disease: Statins have been shown to reduce the risk of heart attack, stroke, and death from heart disease.
  • Reduce the risk of stroke: Statins have been shown to reduce the risk of stroke, even in people who have not had a stroke before.
  • Slow the progression of atherosclerosis: Atherosclerosis is the buildup of plaque in the arteries. Plaque can narrow the arteries and make it harder for blood to flow, which can lead to heart attack or stroke. Statins can slow the progression of atherosclerosis.

Statins are available in several different forms, including:

  • Atorvastatin (Lipitor)
  • Fluvastatin (Lescol XL)
  • Lovastatin (Mevacor)
  • Pitavastatin (Livalo)
  • Pravastatin (Pravachol)
  • Rosuvastatin (Crestor)
  • Simvastatin (Zocor)

Statins are generally safe and effective, but they can cause side effects in some people. The most common side effects of statins are:

  • Muscle pain: This is the most common side effect of statins, and it usually goes away on its own.
  • Liver problems: Statins can increase the levels of liver enzymes in the blood. This is usually not a serious problem, but it is important to tell your doctor if you notice any changes in your liver function tests.
  • Diabetes: Statins can slightly increase the risk of developing type 2 diabetes. This is more likely to happen in people who are already at risk for diabetes.

What New Study Says About Statins And Breast Cancer

Statins may reduce breast cancer mortality rates – Study Reveals

A recent study published in JAMA Network Open has brought to light the potential benefits of statins, a class of cholesterol-lowering medications, in the realm of breast cancer mortality. The study, which involved analyzing data from over 13,000 women diagnosed with breast cancer, revealed that those who took statins following their diagnosis exhibited a 15% lower likelihood of succumbing to the disease compared to those who abstained from statin use.

The study’s authors posit that statins may exert pleiotropic effects, which implies that they possess multiple beneficial impacts beyond simply lowering cholesterol levels. Statins, in addition to their influence on cholesterol, have demonstrated anti-inflammatory and anti-tumor properties.

Although the study does not definitively establish a causal link between statins and a reduction in breast cancer mortality, it underscores the need for further exploration. If subsequent research substantiates the findings, statins could emerge as a valuable tool in breast cancer treatment and prevention strategies.

However, it is crucial to acknowledge that statins are not devoid of potential drawbacks. Side effects such as muscle pain and liver damage have been associated with statin use. Therefore, consulting with a healthcare provider is essential to determine whether statins are a suitable option for each individual.


The objective of the study was to determine whether statin use is associated with a reduced risk of breast cancer mortality.


The study was a retrospective cohort study that included data from 13,000 women diagnosed with breast cancer. The women were followed for an average of 8 years to determine whether they died from breast cancer.

  • Statin use was assessed by reviewing the women’s medical records.
  • Breast cancer mortality was assessed by linking the women’s medical records to a national cancer registry.


The study found that women who consistently took statins after their diagnosis of breast cancer were 15% less likely to die from the disease than women who did not take statins.

These findings were independent of other factors that could affect breast cancer mortality, such as age, stage of cancer, and treatment.

Here’s a summary of key points regarding the study:

  • The study’s observational nature precludes definitive conclusions about the causal relationship between statins and reduced breast cancer mortality.

  • Specific statins were not examined in the study, leaving the question of whether all statins possess the same effect unanswered.

  • The study did not include women taking statins prior to their breast cancer diagnosis, making it unclear whether statins offer a preventive effect.

Despite these limitations, the study represents a promising development in comprehending the potential advantages of statins for breast cancer. Further research is necessary to corroborate the study’s findings and determine whether statins hold a role in breast cancer treatment and prevention.
