Just by coincidence, I usually see my breast surgeon in October, National Breast Cancer Awareness month, but I saw her early this year because she's on maternity leave again. After my visit, I ran into a friend. When I told her where I was, she suddenly looked alarmed. "I didn't know you had breast ... problems," she said, concerned. "I don't!" I jumped to reassure her. Then I was suddenly tongue...

Every new child is full of surprises. You expect him to look and act like other members of the family, but you never know exactly how his genes will fall together. He could have mom's eyes and dad's hair, but it could just as easily be the other way around. Unfortunately, his genes could also carry the blueprint for a serious disease. If you're pregnant or thinking about starting a family, geneti...

Some girls are born with a genetic condition known as Turner Syndrome, which causes a group of related symptoms including short stature, late sexual development, and infertility.
