Thanks for your helpful response (the info on cancer cells not being able to
regulate their growth and cell division...in other words, they're "sick"?) is
useful.

We have 5 samples of five foods set aside (cheddar cheese, cantaloupe, orange
slices, halved strawberries, and yes, cubes of bread) withour any treatment to
use as a control sample.  4 other samples of each of the foods are what we will
be observing to tie in the idea of how scientists/doctors "control" the
spread/progress of cancer.  These four samples were all treated with five drops
of the fungu penicillium (diluted in sterilized water), and THEN:

One sample also treated with two drops of water,
Another                  "         "      "       "     " peroxide
"                             "         "      "       "     " antibacterial
soap

We are observing the growth of the fungus for four weeks.  I guess the idea is
that, in the case of the peroxide and anti-bacterial soap, for instance, if the
growth is slower, then we could tie in how certain cancer treatements also retard 
the growth of cancer in the body.  At least that is the line of thought
we are considering at the moment.

Thanks for any other "expansion" ideas you may be able to provide!

Sincerely,

MARY KINAHAN-OCKAY
