(February 9, 2013 - Insidermedicine Week in Review) From California - Mammography screening every two years is as effective as yearly screening for older women, according to a report published in the Journal of the National Cancer Institute. Researchers reviewed data on over 140,000 women between 66 and 89 years of age. Nearly 3,000 of the women had breast cancer. They found no difference in the rates of advanced breast cancer among women screened annually or biennially. Nearly 50% of women aged 66-74 who were screened annually had false positives, whereas only 29% of women screened biennially had false positives.

From Chicago - The number of Alzheimer's patients could triple by 2050, according to a report published in Neurology. Researchers studied nearly 11,000 Caucasian and African-American individuals aged 65 and older. Participants were followed between 1993-2011 and were assessed every three years for the presence of dementia. Researchers also examined data on death rates, education and future population estimates from the US Census Bureau. Results showed that nearly 14 million people are expected to have Alzheimer's disease by 2050, a threefold increase from the 4.7 million individuals affected in 2010.
