The above table compares the occurrences of prostate cancer diagnoses within our class by year through 2017 to those of the national average as taken from US Government SEER data , specifically, Age-Specific (Crude) SEER Incidence Rates All Ages White Males. Data for projections for 2018 are not available for our age group and beyond.  
The Cohort Size numbers by year comprises those classmates, both grads and those non-grads who are included on the class mailing list (but not those turned back to later classes) -- those with whom we have a fair likelihood of being in contact and hearing from or about should any be diagnosed with PC. The Cohort Size numbers are yearly averages and reflect both mortality and the removal of those previously diagnosed with PC.  The [X]s represent unconfirmed dates of diagnosis.  
The 88 total known cases shown for the class could be understated, i.e. there may still be other classmates with PC out there whom we don't know about. The class is lumped into an average age with a birth year of 1935.  
The cumulative comparison suggests that the class had remained well below the national norm for many years. However, given the small class population size, the differences are not statistically significant and may be explainable as normal sampling variations and/or unreported cases within the class.
