Formation
of
cancer
takes
several
stages
and
many directions
in
the
process.
A
normal
cell
has
to
undergot nLtmerous genetic
changes before
being
developed
into
an
uncontrollably growing
canc-er
cell. Looking
from
this angle,
malignant tumor
is
a
pseudo
genetic
disease.
lt
is
very
closely related
to
environmental
factors.
Thus
preventive
measures should be considered.
