Once
scientists
have
discovered
some
antigen
related
to
cancer,
they
will
then
separate and
proliferate
to
produce
vaccine
which can
help
to
start
up
the
immunity
sYstem
of
the
human
body.
Unlike
traditional
vaccine,
cancer
vaccine cannot
prevent
cancer. Using
it
after the excision
of
tumour
can
help to
prevent
cancer
from moving
and
relapsing.
This
function
of cancer vaccine
is
important
since dOU
of
the
casb
death of cancer were caused
by
minute
cancerometastasis.
These
cancerometastasis
are
verY
small groups
of
cells which cannot be destroyed
by
conventional
surgeiy, radiotherapy
or
even
chemotherap\
They
will
then
form
new
tumours, causing death.
Cancer vaccine
can
start
up
the
immunity
system
of
the human
body
to
destroy
these
groups
of
cancer
cells
before
they
grow
any further.
It is
foreseeable
thal
cancer
vaccine
may become one
of
the
standard
treatment
of
cancer,
bringing
new
hope
to
cancer
patients.
