A study by Kaiser Permanente researchers suggests that women diagnosed with breast cancer in early stage eating dairy products rich in fat after diagnosis are more likely to die of breast cancer than women who eat low-fat dairy products after diagnosis.
The estrogen stimulates the growth of breast cells, including cell growth of breast cancer with hormone receptor positive. Estrogen is created and stored in fat cells. Many researchers believe that dairy products consumed in the United States and otherWestern countries have high levels of estrogen and progesterone in them because most of the milk that is produced by pregnant cows. Therefore, 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 option for women who have been diagnosed with breast cancer, especially hormone receptor-positive breast cancer.
In this study, the researchers wanted to know if eating high-fat dairy products increased the risk of recurrence of breast cancer (cancer recurrence), as well as the risk of dying from breast cancer. For this study, high-fat dairy products include:
- whole milk
- condensed or evaporated milk
The women were followed for about 12 years.
The researchers found that women who reported eating one or more servings per day of rich fat dairy products had a 64% increased risk of dying from any cause and 49% increased risk of dying from breast cancer compared with women who ate fewer servings per day of dairy products high in fat or women who ate low-fat dairy products.
While the results of this study are worrisome, it is important to keep several things in mind.
Although this study shows an association between rich fat dairy products and worse outcomes in breast cancer, which proves the first causes the second. Much more research on the possible link between dairy products rich in fat and breast cancer is needed.
If you have been diagnosed with breast cancer in early stage, it makes sense to do everything possible to minimize the risk of recurrence and improve their chances of survival, including:
- eating a healthy diet that is low in processed foods and sugar
- avoid alcohol
- maintain a healthy weight
- daily exercise
- not Smoking
- stay on track with all the medicines you are taking to reduce the risk of recurrence
