#550 - Cancer Trends

چکیده
U.S. cancer trends are increasingly bleak. There are two ways to judge cancer trends: by incidence rates and by death rates. Cancer incidence refers to the number of new cases of cancer per 100,000 population, ageadjusted. Similarly, the cancer death rate is the number of cancer deaths per 100,000 population, age-adjusted. The purpose of adjusting for age is to eliminate trends that might occur simply because the average age of the population is increasing. In other words, ageadjusting eliminates the argument, "Cancer only SEEMS to be getting worse because people are living longer."

متن کاملTrends and variability in stratospheric mixing: 1979–2005
Changes in climate are likely to drive changes in stratospheric mixing with associated implications for changes in transport of ozone from tropical source regions to higher latitudes, transport of water vapour and source gas degradation products from the tropical tropopause layer into the mid-latitude lower stratosphere, and changes in the meridional distribution of long-lived trace gases. To d...
متن کاملFlame retardants and their metabolites in the homes and urine of pregnant women residing in California (the CHAMACOS cohort).
Organophosphate flame retardants (PFRs), used in consumer products since the 1970s, persist in the environment.
