The ongoing debate about postmenopausal hormone therapy and breast cancer risk may have turned even more muddy: A large, new study suggests that two different types of hormone therapy have opposite effects on women's long-term risk of the disease.
The researchers found that combined hormone replacement therapy (HRT) -- with estrogen and progestin -- increases the risk of breast cancer...
Nearly six years after stopping a five-year regimen of the breast cancer drug anastrozole, women at high risk for breast cancer were 50% less likely to have been struck by the disease, new research shows.
The trial included more than 3,800 postmenopausal women at high risk for breast cancer. They were deemed to be at high risk for a variety of reasons, including having two or mor...
Estrogen therapy may help younger women live longer after having their uterus and ovaries surgically removed, new research reports.
The study found that when women under 60 received hormone replacement therapy (HRT) after surgery, their risk of dying during the 18-year follow-up period decreased by almost one-third compared to women taking a placebo.
New British research is bolstering the theory that elevated levels of sex hormones in the uterus could play a role in autism risk.
Prior studies had already implicated higher uterine concentrations of male sex hormones -- androgens -- in increasing the odds for an autism spectrum disorder, noted a team led by Simon Baron-Cohen. He directs the Autism Research Center at the University o...
New insight into why women get more migraines than men could lead to better treatments, researchers say.
The results of lab and animal experiments suggest changing levels of the female sex hormone estrogen make cells around a key nerve in the head and connected blood vessels more sensitive to migraine triggers. And that increases migraine risk.
A new international review suggests that having more body fat may protect premenopausal women from developing some types of breast cancer.
"We found strong evidence of an inverse association of body mass index [BMI] with risk of breast cancer diagnosis before menopause, with lower breast cancer rates among women who were heavier compared with women who were leaner," said study author...
A pregnancy drug that has been banned for decades may increase the risk for attention-deficit/hyperactivity disorder (ADHD) generations later, new research suggests.
The study found that the grandchildren of women who took a synthetic estrogen, diethylstilbestrol (also known as DES), to prevent pregnancy complications between 1938 and 1971 are more likely to have the disorder.
Newer versions of the birth control pill carry a similar increased risk of breast cancer as earlier ones that were abandoned in the 1990s, a new study reveals.
Women taking modern formulations of the pill have a 20 percent increased risk of breast cancer compared with those who've never been on hormonal contraception, the study of almost 2 million Danish women found.
