Is it true that soybeans can reduce the risk of breast cancer?

If you are looking for an alternative to protein, then soybeans can be the best choice. Because soybeans contain protein, amino acids, and other nutrients that are important for the body. In addition, soy is also touted to reduce the risk of cancer. Is this claim true?
The Link Between Soybeans and Breast Cancer
Breast cancer is a condition when there is abnormal and uncontrolled cell growth in breast tissue. Hormones, genetics, lifestyle and environment are some of the factors that can cause this condition.
Consumption of foods derived from soybeans, such as tofu, tempeh, edamame, and soy milk is often associated with a reduced risk of several types of cancer and tumors, including breast cancer.
Please note, in the beans Soy contains isoflavones which are plant versions of estrogen (phytoestrogen).
This phytoestrogen has a different structure from human estrogen and has weaker properties. In addition, phytoestrogens will not turn into estrogen when consumed.
Isoflavones can actually protect the body from cancer caused by hormones. This is due to its ability to block natural estrogen in the blood.

A study conducted in 2016 stated that Asian women who consumed a lot of soy had a 30 percent lower risk of developing breast cancer.
Another study involving more than 73 thousand women in China revealed that participants who consumed at least 13 grams of soy protein per day had an 11 percent lower risk of developing breast cancer, compared to those who consumed less than 5 grams of soy protein.
In addition, it is also known that soybean supplementation can prevent side effects from cancer chemotherapy and radiation therapy.
Other Ways to Prevent Breast Cancer
If you are concerned about your risk of developing breast cancer, here are some ways you can reduce your risk of developing this condition, including:

2. Maintain Ideal Body Weight
Overweight and obesity can cause changes in the body that increase the risk of cancer. Fat deposits can cause prolonged inflammation and insulin levels that exceed normal limits.

4. Giving Breast Milk to Babies
Research says that mothers who breastfeed their children can reduce the risk of breast cancer. In addition, breastfeeding for longer than 6 months may provide more protection from breast cancer.
Breastfeeding can cause hormonal changes that can delay menstruation. This will reduce the duration of exposure to hormones that cause cancer cell growth, such as the hormone estrogen.
