A new study of more than 800 breast cancer patients shows the majority still reported some level of pain a year after surgery. Pre-operative pain, chemotherapy and radiation were some of the factors.
A good night's sleep may be critical for maintaining brain health. Researchers in Sweden conducted a study where participants were sleep-deprived for a night. In the morning, there were increased blood concentrations of certain proteins in their brains. These molecules typically rise when a person suffers brain damage, so researchers conclude lack of sleep may promote processes that can damage or kill neurons in the brain.
