Hi Jimmy, I guess it would depend on how good the nurses are at doing IV's.  I
was never even offered the choice of a port and only found out about them later
after reading about it online and then talked with some while doing radiation
after I finished AC who had ports.  At our health care facility they are only
used if one has a problem with their veins.
Some people love them.  Others have problems with them--discomfort and it still
hurts when they use it to access it.  It is helpful for those who have bad
veins which often requires several sticks before they can access the vein.
Interestingly, I had 56 chemo-related infustion and can only use my right
arm/hand.  Usually they get it in the first time.  Once or twice they had to do
2 or 3 sticks, but I didn't have a problem with that.  Now these are trained
nurses doing it.  I do have a hard time with some of the lab techs because I
supposedly have rolling veins -- whatever that is. So, I guess it depends on
how well trained the chemo nurses are.  At our health care facility only RN's
start chemo.
Personally, I am glad I didn't get a port.  However, I don't know if I'd feel
that way if the nurse's did have a hard time.  If at all possible perhaps you
could get info about the oncology staff re. such.  One thing, although AC cam
leak I think that is rare.  The biggest problem, from what I gather, is whether
or not the nurse or whomever can start the IV in the first place.
One suggestion--your wife could try it without a port and if she doesn't like
the way it goes or does have a problem, then a port could be put in if she'd
want.
I forgot to mention one of the reasons a port would not have been the best of
choices in my case was because  with my breast cancer there was also dermal
lymphatic involvement.  The port itself wouldn't have been the problem, per se,
but disturbing the upper chese area where it usually is put, would have been.
However, there are also different types of devices that can be used and I did
see someone with IBC (inflammatory b.c.) who had an external port on her thigh.

My wife had Stage IV breast cancer and because of the amount and
frequency of the chemo given, was not given a choice. She had an
internal port at the oncologist's insistence, and was happy she had
one. She had chemo 3 times weekly for 6 months, in addition to a 3 day
pump each wek. That was followed up by weekly chemo for another 6
months! Her veins would not have handled all those sticks, and the onc
nurse prided herself on getting IVs on first stick.

I had colon cancer, and also had an internal port for the chemo, but
it became infected and had to be removed, and replaced with tubes
hanging from my chest. A real bummer to keep them dry while taking a
shower....

A surgeon put in both our ports.
