Fertility is a priority for many young women with breast cancer, yet new research has found many have little knowledge about fertility issues, leading to confusion and conflict around planning for a family.

Young black athletes with sickle cell trait might be susceptible to sudden death
The sickle cell trait could be a cause -- albeit rare -- of sudden death in young African-American competitive athletes, most commonly during football training, according to a scientific poster that will be presented at the American College of Cardiology Scientific Sessions, April 1-3, in New Orleans.

New evidence from cardiac researchers at the Intermountain Medical Center Heart Institute in Utah demonstrates that routine periodic fasting is also good for your health, and your heart.

Hypothermia proves successful in younger cardiac patients too
Young adult patients with genetic heart diseases, such as hypertrophic cardiomyopathy (HCM), substantially benefitted from therapeutic hypothermia, which could further extend the role for this treatment strategy in new patient populations, according to a scientific presentation at the American College of Cardiology (ACC) Scientific Sessions in New Orleans, April 1-3.
