Sometime using a visual aid helps to make a point.
The link below is to a page containing a series of statistically based graphs that plot and display various facts about
prostate cancer, arranged by age and age groups. (The page can also be displayed by googling "prostate cancer age graphs" and clicking on the relevant line).
I invite you to click on the link. If you do, you will see a series of graphs, and for
every one of them, you will also see that the number of men aged 38 "at first diagnosis" is
virtually off each graph, it is such a small number!
It even looks to me, with my poor graph reading skills, that these graphs are saying that a 38-year-old man probably has a about
a 99 % change of
not having PCa!
A picture is worth a thousand words?
Take a look and see for yourself!
