As far as I know chemo is one of the few things that is an absolute no for
BF.  Maybe you can help her work out a plan, BF for a short period of time
while she is healing from surgery (usually 4-6 weeks), then wean and begin
chemo.  Colon cancer can be vicious and her choice is BF for x amount of
time and die or BF briefly to turn on baby's immune system, then wean, do
chemo and maybe live to raise baby.  Bluntly, a dead mom doesn't help
anybody.  It is such a sad situation.  Another thought - after surgery she
may have radiation.  I think it depends on the kind of Ca.  My dad had both,
with excellent results.  Another problem is contact with baby if she has
radiation.  A good radiologist may be able to assess this risk.  I think it
is a reasonable concern.   This isn't a win-win situation.  And
unfortunately a very pregnant woman with diagnosed cancer is in an extremely
vulnerable emotional state.  I just don't see bf, other than a very brief
time.  You'll have to help her and her family through this, deal with
choices, grief, etc.  It's a very scarey time.  My 36 y.o. daughter is
currently getting radiation for Ca.  She has 4 children 4-15 yrs. old.  I
can personally tell you Ca is hell - for all involved.
