Why Do Pregnant Women Have a Lower Risk of Breast Cancer?

Breast cancer is one of the most common types of cancer among women.

However, studies show that pregnant women have a lower risk of developing breast cancer compared to non-pregnant women.

This phenomenon has attracted the attention of many health experts and further research to understand the mechanism behind it.

1. Hormonal Changes During Pregnancy
One of the main factors thought to contribute to the reduced risk of breast cancer during pregnancy is hormonal changes. During pregnancy, a woman's body experiences a surge in hormones, especially estrogen and progesterone. These hormones play a role in preparing the breasts for breastfeeding and may also serve to protect breast tissue from the development of cancer cells.


2. Breast Tissue Formation
During pregnancy, the breasts undergo significant changes. Breast tissue that previously existed will develop and form new, denser tissue. This process makes the breast cells more resistant to factors that can trigger cancer. Research shows that this development can reduce the chance of cell mutations that could potentially lead to cancer.


3. Gestational Age and Cancer Risk
Some studies suggest that women who become pregnant at a younger age tend to have a lower risk of breast cancer. This may be related to different hormonal cycles and genetic factors that play a role in cancer development. On the other hand, women who become pregnant at an older age may not get the same protective benefits.


4. The Role of Breastfeeding
After childbirth, breastfeeding also contributes to breast cancer risk reduction. Women who breastfeed may have a lower risk because breastfeeding helps lower estrogen levels in the body and reduces the number of menstrual cycles, which are associated with breast cancer risk.


5. Lifestyle Factors
In addition to biological factors, lifestyle also plays an important role in breast cancer risk. Pregnant women often pay more attention to their diet and general health. Healthy habits adopted during pregnancy, such as a balanced diet, regular exercise, and avoiding alcohol and cigarettes, can contribute to a reduced risk of breast cancer.

Conclusion
Although pregnant women have a lower risk of developing breast cancer, it is important to remember that every woman has different risk factors. Early detection and regular check-ups remain very important, especially for those with a family history of breast cancer. With a better understanding of the link between pregnancy and breast cancer, we can raise awareness and promote healthy lifestyles among women. Thus, pregnancy is not only a period of growth and development for both mother and baby, but also provides a new perspective on women's breast health.
