A new study shows women 66 and older don't gain any benefit from having mammograms once-a- year instead of every other year.
This study found that for older women, annual screenings don't find any more serious, late-stage cancers than screenings every other year.
Researchers found having screenings more often led to more false positives and unnecessary biopsies. Experts say that increases a woman's anxiety and wastes money and time.
Researchers say women over 66 should talk to their doctors about whether they should have mammograms every year or every other year.
A woman in Texas has given birth to two sets of identical twins at once.
Tressa Montalvo's babies -- all boys -- were born Valentine's day at a Houston hospital.
She and her husband Manuel already have a two-year-old son. She says they didn't use fertility drugs.
Experts say the odds of giving birth to two sets of identical twins at once is 1-in-70 million.
The babies were born at 32 weeks and are doing well. Their names begin with the first four letters of the alphabet -- Ace, Blaine, Cash, and Dylan.
