Miscarriage can increase the risk of breast cancer, and the more miscarriages a woman has, the greater her risk of breast cancer. Because the hormones in the body increase during pregnancy, the breast gland becomes enlarged and engorged. The abortion aborts the pregnancy and the hormone level in the body suddenly decreases, the breast gland suddenly stops growing and the alveoli shrink, which can cause ovarian dysfunction and also cause stagnation of the breast gland, causing lumps and various breast diseases. Recently, Australian Queensland MP Freya Ostapovitch said that abortion can increase the risk of breast cancer. This was said during her speech to Parliament on Tuesday this week. During her speech Ostapovitch cited a “controversial study” conducted last year by Chinese researcher Yubei Huang, a researcher from the School of Medical Oncology at Tianjin Medical University, who said that abortion increases a woman’s risk of breast cancer by 44 percent. Ostapovitch, who was a nurse before becoming a congresswoman, spoke to Congress in hopes of bringing more attention to breast cancer. She also noted that the more miscarriages a woman has, the greater her risk of breast cancer. In fact, Huang’s study is not the only one to point out the link between abortion and breast cancer, as six studies in India and Bangladesh have shown that abortion increases the risk of breast cancer. However, Ostapovitch also pointed out that normal pregnancy and breastfeeding can reduce a woman’s risk of breast cancer. Why abortion increases the risk of breast cancer? After pregnancy, the hormones in the body increase, the mammary glands become hypertrophic and engorged, the ductal system in the mammary glands develops vigorously, and a large number of alveoli and glandular lobules are formed to prepare for lactation. After abortion, the pregnancy is terminated and the hormone level in the body suddenly decreases, the growth of breast gland stops and the glandular follicles shrink. This ups and downs phenomenon can cause ovarian dysfunction, as well as stagnation of the breast gland, causing lumps and various breast diseases, including breast cancer.
