Looking at the SEER data (
seer.cancer.gov/statfacts/html/prost.html) for 2004-2008 it is clear that our group here is skewed younger. However, there are some commonalities.
If you group the categories together so they match up as much as possible, you can see that in the SEER data, the largest bunch of guys was in the 55-64 age group (30.7%). The same is true for our group, only more so. 40.3% of our respondents were in that group.
The national data shows more of a spread across the later years than ours does. Nearly a quarter of men nationally are diagnosed at 65 and up, but only 12.6% of our group.
The biggest difference is that we have far more in the 44 and under category--more than 10 times the national average.
This all makes sense when you consider that demographic group least likely to be online is 65 and older, precisely where most (59.6%) of PCa diagnoses are received.
