TUESDAY, June 4, 2019 (HealthDay News) -- Breast MRI screening is a good way to detect small tumors, but it's unclear how much it benefits women with a history of breast cancer, a new study finds.

Right now, experts recommend that breast cancer survivors have yearly mammograms to help catch any recurrences early. An unresolved question is whether adding breast MRI to that screening is...

TUESDAY, May 28, 2019 (HealthDay News) -- Some folks are more prone to fainting than others, and the reason might lie in their DNA.

Danish researchers who analyzed millions of gene variants in DNA of 400,000 people have zeroed in on a gene that increases a person's risk for fainting.

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...

What is sickle cell anemia? Sickle cell anemia is a disease of red blood cells that is passed from parent to child. Normally red blood cells contain a protein called hemoglobin A, which carries oxygen to all the organs in the body. With sickle cell anemia, however, the body makes a different kind of protein, called hemoglobin S. The problem is that when a red blood cell with hemoglobin S relea...

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. First recognized in 1938 by a doctor named Henry Turner, the condition occurs when one of the two X chromosomes is either missing or abnormal, with some genetic material missing. Turner Syndrome is relatively common, oc...

What is Prader-Willi Syndrome? Prader-Willi Syndrome (PWS), which was named for the two doctors who first identified it, is a complex genetic disorder that causes short stature, weak muscle tone, incomplete sexual development, and obesity, as well as cognitive disabilities and behavior problems.
