Study finds pregnancy safe after breast cancer
CHICAGO – A study done in Europe gives reassuring news for breast cancer survivors who want to have children: Those who later became pregnant were no more likely to have their cancer come back than those who did not have a baby.
It's a big issue – the average age of moms has been rising in the United States, and more women are being diagnosed with breast cancer in their childbearing years. About 11 percent of new breast cancer cases in the U.S. are in women under 45.
The study, which involved more than 1,200 breast cancer survivors, is the largest so far on women whose cancers were fueled by hormones, which rise in pregnancy and theoretically, might spur a recurrence.
Study leader Dr. Matteo Lambertini of the Jules Bordet Institute in Brussels said the results show that “pregnancy after breast cancer can be considered safe.”
The results show “fairly convincingly” that women don't have to worry, said Dr. Richard Schilsky, chief medical officer for the American Society of Clinical Oncology.
A big study underway now in the U.S. and other countries is taking this research one step further, testing whether it's safe for breast cancer survivors who want to get pregnant to temporarily suspend taking the hormone-blocking drugs like tamoxifen usually recommended for five years after initial treatment.
