A new study in Belgium is providing reassuring news for breast cancer survivors who want to have children.
The research suggests that survivors of the disease who later became pregnant were no more likely to have their cancer come back than those who did not have a baby.
The study is the largest so far on women whose cancers were fueled by hormones, that rise in pregnancy and theoretically, might spur a recurrence. Experts say the average age of mums has been rising, and more women are being diagnosed with breast cancer in their childbearing years.
The research involved more than 1,200 breast cancer survivors. Women in the study must have used hormone blockers for at least 18 months before stopping, and can suspend treatment for up to two years to enable pregnancy, delivery and breastfeeding.
