[Bulk] [ RadSafe ] Doubts on Cancer Statistics

[Wes Van Pelt]

Emilio,
The peak in cancer mortality at 1990 is quite striking. You are right to ask
the question. The value plotted is cancer mortality per 100,000 residents.
If the average age of residents decreased after 1990 (due to immigration and
births) the graph would go down even if the chance of cancer mortality at
any specific age were constant.  But this is just a guess.

I could not load your second URL...the longest URL I have ever seen!  Can
someone make it into a tinyURL?

Hello Radsafers, searching for cancer statistics i run across
"http://statecancerprofiles.cancer.gov" where I found a peak in the number
of cancer cases around 1990. Could someone explain the reason of this to me?
shouldn't this behaviour be unsual?

The first one provides a clearer view of what i'm talking about, the second
page was a string-generated one I made to check he tendencies in every
state, although it takes a few seconds to load:
