Statins May Lower Cancer Risk, Too
If you have high cholesterol, chances are your doctor has prescribed you a type of medication called a statin. By lowering cholesterol, these pills help prevent heart disease, the leading cause of death in the U.S. Some research suggests statins may also play a surprising role in preventing another major health condition. They may lower your risk for cancer.
Cholesterol is an important substance that helps the body function. Your liver makes cholesterol - enough for your body's needs. But the foods you eat also add to the amount of cholesterol in your blood. When your body has too much of the wrong type of cholesterol, it can form plaque along the artery walls. Plaque clogs your arteries and may eventually lead to heart disease, as well as disease in other parts of the body.
Enter statins. They work by limiting the amount of cholesterol that your liver naturally makes. Your doctor may prescribe a statin if healthy lifestyle changes, such as eating better and exercising more, aren't enough to control your cholesterol levels.
Scientists have known for quite awhile about the ability of statins to reduce cholesterol. But their potential to lower the risk for cancer is a newer notion. Several studies have suggested that people who take statins may be less likely to develop prostate cancer, breast cancer, and colorectal cancer. A recent study even found a link between statin use and lower rates of stomach cancer in people with diabetes.
Statins may also help reduce the risk for death in people who already have cancer. Researchers from Denmark recently conducted a nationwide study on statins and cancer. They found that people diagnosed with cancer were less likely to die from it if they were taking statins. This link may be related to how statins work in the body. As they lower cholesterol, they may affect how cancer cells function, limiting their growth.
Despite these encouraging results, health experts, including the National Cancer Institute, don't yet recommend taking statins to prevent or treat cancer. Although some studies point to a positive connection, others do not. Ongoing clinical trials may eventually give a firm answer on the value of statins in cancer care. For now, the use of statins is limited to their proven power to lower cholesterol.
