Can pregnancy increase the risk of breast cancer?

The importance of breasts to women is self-evident. For most women, pregnancy is their natural duty and the most beautiful period. However, during this period, women's health probability is relatively low, and some diseases are more likely to invade their bodies, but breast cancer, the number one killer that endangers women's health, is not a big deal. Can pregnancy increase breast cancer? Studies have shown that pregnancy can reduce the probability of breast cancer.

Experiments have shown that fetal microchimerism in the mother's body can provide protection for the mother. Gaddy said that he hopes this experiment can lead to other studies on fetal cells. He said: "Most studies on chimerism focus on its negative impact on many autoimmune diseases, but a large number of women have microchimerism in their bodies after pregnancy. Nature must have its reasons for doing this, perhaps to eliminate cancer cells in the body, or it may be involved in tissue repair.

Researchers from the University of Washington and the Fred Hutchison Research Center in the United States investigated 82 women, 35 of whom were diagnosed with breast cancer. The researchers sampled and compared the male fetal DNA (DNA) in the mother's blood and found that 14% of the mothers with breast cancer had male fetal DNA in their blood, while the rate of male fetal DNA in the blood of women without breast cancer was 43%.

Since male fetal DNA is easier to separate than female fetal DNA, the researchers only looked at women who were pregnant and gave birth to male fetuses. "My hypothesis is that fetal cells may recognize breast cancer embryos in the mother's body and kill them before the cancer cells start to act," said VK Gaddi, the lead researcher on the study.

After the above introduction, I believe everyone has a certain understanding of the relationship between pregnancy and breast cancer. In our lives, it is very important for female friends to understand the relevant knowledge of breast cancer. Pregnancy reduces the risk of breast cancer for female friends a lot, and they can stay away from breast cancer as soon as possible.
