Breastfeeding Benefits Cancer Survivors

   

 We've all heard about the benefits of breastfeeding.  It's associated with better digestion for baby, improved immunity, protection against illness and a lower risk of Type 2 diabetes, breast cancer, ovarian cancer and depression for women.  What you probably haven't heard about is the effect of breastfeeding on women who have had cancer during childhood.  Research out of St. Jude's Children's Research Hospital in Memphis, Tennessee finds breastfeeding can protect childhood cancer survivors against some of the health problems associated with their cancer and related treatments. 
  From Time: 

Cancer treatments often involve exposure to toxic chemotherapy and radiation, and these agents can translate to as much as a 25-fold increased risk of breast cancer among female survivors by the time they reach adulthood. But studies of cancer incidence among new mothers found that breast-feeding can lower this risk by 11% to 25% for women who adopt the practice for 6 months to 24 months throughout their reproductive years, compared with those who don't breast-feed. Lactation, say experts, triggers changes in the breast and in the combination of hormones circulating in a mother's body, all of which may collectively counter the formation of malignancies in breast tissue.
Cancer treatments can also sap young bones of calcium and leave the skeletal system more vulnerable to osteoporosis, and while breast-feeding can lead to an initial loss of calcium, studies have shown that over time, women who breast-fed rebounded beyond their initial bone density levels and ended up strengthening their bones in the process.
The physical act of breast-feeding is also a well-known calorie burner, and mothers who nurse their babies often lose more weight in a shorter period of time than mothers who opt to formula-feed.
In addition, nursing is associated with a lower risk of diabetes and other heart disease risk factors such as high cholesterol, a good thing for childhood cancer survivors, who are often at heightened risk of heart-related health problems.
So taken together, the latest study, conducted at the St. Jude Children's Research Hospital, found that breast-feeding has a positive impact on a number of systems that are affected by childhood cancer. “Breast-feeding may be one more of those behavioral interventions like not smoking, eating a healthy diet and exercising that we can offer to childhood cancer survivors to reduce their later health complications,” says James Klosky, a psychologist at St. Jude and a co-author of the study.
The results aren't a guarantee that all women who survived cancer as children and then decided to breast-feed their own children will get a clean bill of health.
