Dairy products that are derived from cows milk may be associated with an increased risk of breast cancer. Breast cancer is the second most common cause of death for American women, with over 40,000 new cases being diagnosed yearly. Recent studies have found that frequent consumption of processed cheese may lead to this disease.
The National Cancer Institute conducted a study on 1,941 women who had been diagnosed with breast cancer. Researchers concluded that women who consumed cheddar or American cheese increased their risk of breast cancer by 53%. Those who drank the most cows milk were found to be at a 58% increased risk.
Saturated fats in milk and cheese have been found to contain cancer-causing toxins and hormones. Since pesticides are frequently used on graze land, cows ingest harmful toxins that are then transferred to human consumers.
Growth hormones such as insulin-like growth factor (IGF-1) contained in dairy products were among the sources linked to breast cancer.
In an additional study done by Kaiser Permanente, researchers found that women diagnosed with early-stage breast cancer had lower chances of survival if they incorporated full-fat dairy into their diet. The hormones within dairy products speed up the progression of the disease as they stimulate the cancer cells.
While some health professionals say that no dairy is the best, some low-fat products can still be part of a healthy diet. Low fat or Greek yogurt and cottage cheese are considered healthier alternatives than many other animal products.
