Researchers in Wisconsin say sleep-disordered breathing - commonly known as sleep apnea - can increase a patient's risks of dying from cancer.

According to their study, the lack of oxygen from sleep apnea can help cancerous tumors grow.

People who had severe sleep apnea were almost 5 times more likely to die from cancer than people who have no sleep-breathing problems.

Obese teenagers who have no symptoms of heart disease already have heart damage.

That's according to a new study presented to the European Society of Cardiology.

Scientists found that obese teens, who showed no signs of heart disease, had damaged hearts with thicker walls.

Researchers say more studies are needed to determine if the heart damage can be reversed if the teens lose weight.

According to researchers in St. Louis, folic acid may reduce some childhood cancers, especially kidney cancer and brain tumors.

The FDA has mandated foods are fortified with folic acid since 1998 and researchers say since that time, certain cancer rates among children have dropped.
