We Drink It Daily, But Don’t Know That It Causes Breast Cancer

A study done by Kaiser Permanente researchers suggests that women diagnosed with early-stage breast cancer who eat full-fat dairy products after diagnosis are more likely to die from breast cancer than women who eat low-fat dairy products after diagnosis.

The hormone estrogen stimulates breast cell growth, including the growth of hormone-receptor-positive breast cancer cells. Estrogen is created and stored in fat cells. Many researchers believe that dairy products eaten in the United States and other Western countries have high levels of estrogen and progesterone in them because most of the milk is produced by pregnant cows. So it might be possible that low-fat dairy products have lower levels of estrogen and progesterone because most of the fat has been removed. This suggests that low-fat dairy products may be a better choice for women who’ve been diagnosed with breast cancer, especially hormone-receptor-positive breast cancer.

Breast-Cancer

In this study, the researchers wanted to know if eating full-fat dairy products increased the risk of breast cancer recurrence (the cancer coming back), as well as the risk of dying from breast cancer. For this study, full-fat dairy products included:

  • whole milk
  • condensed or evaporated milk
  • pudding
  • ice cream
  • custard
  • flan
  • cheese
  • yogurt
  • butter

The women were followed for about 12 years.

The researchers found that women who reported eating one or more servings per day of full-fat dairy products had a 64% higher risk of dying from any cause and a 49% higher risk of dying from breast cancer compared to women who ate fewer servings per day of full-fat dairy products or women who ate low-fat dairy products.

While the results of this study are troubling, it’s important to keep several things in mind.

While this study shows an association between full-fat dairy products and worse breast cancer outcomes, it doesn’t prove the first causes the second. Much more research is needed on the potential link between full-fat dairy products and breast cancer.

If you’ve been diagnosed with early-stage breast cancer, it makes sense to do everything you can to minimize your risk of recurrence and improve your chances of survival, including:

  • eating a healthy diet that’s low in processed foods and sugar
  • avoiding alcohol
  • maintaining a healthy weight
  • exercising daily
  • not smoking
  • staying on track with any medicines you’re taking to reduce the risk of recurrence
