[net.med] odd cancer incidence statistics

pgf@hou5h.UUCP (Paul Fox) (09/28/83)

I was once told (or perhaps I read) a couple of strange "facts" about
cancer, and I was wondering if anyone out there could refute or 
substantiate them.  I don't even know where to start looking for the answers.
The first was that among the patients of mental hospitals, the recovery
rate from cancer is on the order of 100% (or at least very high).  The 
implication was, I suppose, that those patients were less worried about their
illness-- maybe cancer is partially psychosomatic?  The other statistic was
that there is a higher incidence rate of cancer among people whose last
names begin with the letter 'S'.  This may of course be a restatement of
the percentage of *all* people whose last names begin with 'S' (i.e. more
of the people who have cancer have last names that begin with 'S'...).

I was just curious about this stuff... makes for good trivia, even if you don't
understand any of the actual issues.

I heard somewhere that there was some evidence that uptight or neurotically
anxious people had a higher-than-average risk of getting cancer in the first
place.  If this were true, then what Paul Fox heard about people
in mental institutions having higher cancer cure rates can probably be
explained in the following manner:  Some one whose psychology causes
him to mismanage stress or experience undue anxiety will have psychosomatic
effects resulting in a greater tendency to develop some type of cancer.  If
that person is placed in a mental institution before the cancer is discovered,
his environmental situation changes in such a manner as to reduce stressful
or anxiety-producing situations and demands.  Since the development of cancer
in this individual was partly related to that stress, a reduction in stress
might make his body better able to fight off the cancer than someone whose
immune functions were impaired for other reasons.  Note that I am implying
that healthy immune function helps recovery and that anxiety impairs immune
function.
