JK...Most studies find that death rate from various causes (including
cancer, heart attacks, etc.) is similar between men with PCa and the
general population.  But as Newschaffer, et. al. point out, such
studies are frought with bias (cause of death reporting).

Causes of Death in Elderly Prostate Cancer Patients and in a Comparison
Nonprostate Cancer Cohort; Craig J. Newschaffer, Koichiro Otani, M.
Kathleen McDonald, Lynne T. Penberthy; Journal of the National Cancer
Institute, Vol. 92, No. 8, April 19, 2000

A more recent study (J Urol. 2005 May;173(5):1526-9; Higher than
expected association of clinical prostate and bladder cancers; Singh A,
Kinoshita Y, Rovito PM Jr, Landas S, Silberstein J, Nsouli I, Wang CY,
Haas GP.) concludes that, "Patients with PCa have higher incidence of
bladder cancer and those with bladder cancer have a higher incidence of
PCa."...Best wishes and good health, ron

Years ago, it seems that there was a higher frequency of cancer occurrence
in people who have had prostate cancer previously.  However, I wonder if
they culled out those who had radiation treatment; which I imagine is very
much a cancer causer.

I remember this question being raised a couple of years ago on
this group.  A doctor who was participating at that time said that
it is thought that people who have any form of cancer are thought
to have a little higher chance than others of getting other cancers.
The theory was that if you have a genetic predisposition to cancer
then it may show up in more than one form.

However I'm not aware of any statistics for or against that view.
