Women's Health: Association between breastfeeding, reduced risk of aggressive breast cancer ♦ Genetic tests of amniotic fluid could guide timing of delicate births

Association between breastfeeding, reduced risk of aggressive breast cancer Breastfeeding is associated with a lower risk of developing an aggressive form of breast cancer called hormone-receptor negative, a large international study shows. Hormone-receptor-negative (HRN) breast cancers are more likely to be aggressive and life-threatening. This subtype is more commonly diagnosed in women under age 50
More precise due dates for pregnant mothers Until now, measuring cervical length has been used to help detect women with a high chance of premature labor -- the shorter the cervix, the more likely labor is imminent. Now researchers suggests that a routine screening could help narrow the estimated date of delivery for pregnant women.
Genetic tests of amniotic fluid could guide timing of delicate births Analyzing gene expression of an expectant mother's amniotic fluid could give doctors an important tool for deciding when it is safe to deliver premature babies. Researchers report a way to test RNA and specific genetic signatures in amniotic fluid to see whether fetal lungs -- and potentially other organs -- are mature enough for a safe and viable delivery.
Researchers identify association between reproductive factors and risk of death Reproductive factors in women, such as a later starting age of menstruation, having children, breastfeeding and use of oral contraceptives, are associated with a reduced risk of death. A better understanding of how these factors can influence long-term health could help in the development of clinical strategies to improve women's health.
