(CBS) - Fewer Americans are getting screened for cancer. Researchers in Miami found the number of people who underwent preventive screenings during the last decade decreased significantly. The study found people were not getting screened for breast, cervical and prostate cancer as often as the government says they should. The only exception was colorectal cancer screenings. The authors think rising health insurance costs and conflicting opinions about some of the guidelines may have lead to the decline.
(CBS) - An MRI is an effective way to screen patient's for Alzheimer's disease, according to a new study from the University of Pennsylvania. Researchers found the test was accurate 75 percent of the time. They say testing a patient's spinal fluid with a lumbar puncture is even more accurate, but an MRI is non-invasive and costs less. Researchers say for the 25 percent of cases that are borderline, a lumbar test would be advisable.
(CBS) - Kindness may be the key to prevent bullying. A new study of 9 to 11 year olds found children who were assigned to perform acts of kindness like sharing their lunch or giving their moms a hug reported increased feelings of happiness. Classmates were also more likely to choose them to work on school projects. Researchers say the more a child has acceptance from his or her peers, the less likely he or she will be bullied.
