Study: False-Positive Mammograms Have Minimal Effect on Anxiety
Women whose mammograms suggest the presence of breast cancer that is eventually ruled out by further testing experience slightly increased anxiety that does not affect their overall health, according to a new study in the Journal of American Medical Association (JAMA) Internal Medicine. Researchers from the Geisel School of Medicine at Dartmouth College compared 534 cancer-free women whose mammograms initially suggested breast cancer to 494 women whose screenings were negative. The women were interviewed after the first mammogram but before they were cleared of a cancer diagnosis and again a year later. Immediately after their first mammogram, the women who received false-positive results had more anxiety than those who received a clean bill of health but the anxiety leveled off after one year. There was no difference in overall health between the two groups of women. Read more on cancer.
Bullying Victims Feel Psychological Effects into Middle Age
Children who are bullied suffer the psychological affects for years to come, leading to increased risk of depression and other mental health issues, according to a new study in the American Journal of Psychiatry. British researchers have found that children bullied at the ages of 7 and 11 experienced feelings of poor general health at ages 23 and 50 and poor cognitive functioning at 50. The study used surveys that were conducted over 50 years, looking at children who said they were bullied occasionally or frequently at 7 and 11, and comparing the impact at ages 23, 45 and 50.

Earth Day: The Impact of the Environment on Health
April 22 is Earth Day and people across the country are taking action to protect and improve our environment. The quality of our environmental has significant effects on our overall health. Air pollution, such as ground-level ozone and airborne particles, can irritate the respiratory system, induce asthma and even lead to lung disease. In addition, UV exposure due to ozone layer depletion can lead to skin cancer, cataracts and suppression of the immune system. Below are tips to help create a healthier planet today:
- Conserve energy and improve air quality by turning off appliances and lights when you leave a room.
- Keep stoves and fireplaces well maintained to reduce air pollution.
- Plant deciduous trees near your home to provide shade from UV rays in the summer.
- Buy energy efficient appliances produced by low- or zero-pollution facilities.
