A new study found that: pregnant women, fetal body through the uterus will have a strong defensive force cells to pass the parent, thereby reducing the mother’s risk of breast cancer.
Experts on the maternal blood of male fetal DNA (DNA) sample comparison, with breast cancer were surveyed, 14% of the maternal blood containing male fetal DNA, the blood of women without breast cancer within the masculine gender fetal DNA, a ratio of 43%.
As the male fetal DNA more easily than women to achieve separation of fetal DNA, researchers in the survey only male fetus pregnancies and childbearing women in the study. Experts say: “My hypothesis is that fetal cells may be identified in the mother’s breast cancer cells within the embryo, and the cancer cells before the event began to be killed.”
The researchers hope that experiments show that the existence of fetal cells in maternal – fetal microchimerism for maternal protection. Hope that this experiment can lead others on the fetal cell research. Experts said: “With regard to chimera, most studies have focused on autoimmune diseases, it caused many negative effects, but a large number of women in pregnancy have emerged in vivo microchimerism Nature definitely has its own reasons for doing so may be to clear the body of the cancer cells, it may also be involved in tissue repair. “
