<BR> E. Excel international have
successfully found a

on
<BR>that machine " made in E. Excel". Surprise!!!
<BR> This is really a amazing
news.. Do you know that we can check out the
<BR>cancer
<BR>before it become serious? How many life we can save?
<BR> Another most important thing
is all of our products have been proved that
<BR>will be useful to prevent cancer. E. Excel has found the main reason
of
<BR>suffering from cancer. It's because our body cannot repair DNA which
has
<BR>been
<BR>damaged by cancer cells. After the experiment, we found that all of
our
<BR>products have the ability to repair DNA, that means that we can prevent
the
<BR>cancer permanently.

Wonderfull, another source of shoulder pork and ham on this net.
First of all, DNA is not damaged by cancer cells, but damage to DNA is
just one mechanism that leads to cancer. Other mechanisms include defects
in inherited genes which modulate cell growth (oncogenes such as p53 and
bcr -1), enviromental signals that cause metaplasia (tobacco, fat -- derived
estrogens), and failure of senescent cells to undergoe apoptosis (programmed
cell death).
<P>As far as a single test to detect cancer -- 30 years ago CEA was thought
to be the test. It's helpful in known cancer cases, but isn't sensitive
enough to be used as a screen. Ten years ago, a researcher published magnetic
resonance data (never confirmed). Five years ago, everyone thought that
CA-125 screening could detect early ovarian cancer. However, anything which
irritated the pelvis could cause a mild elevation while a higher cutoff
misses some early cases.
<P>In other words, I doubt you have the "gold standard" single test for
cancer (and yes, I checked out your web page.</HTML>
