Can eggs, chicken or whey protein cause rise in psa - am mcrpc patient on 2nd line rx

Sorry for long post but its not as easy for me to make these shorter
as it used to be.

Want to ask some very targeted questions on your experiences
with certain foods that can help with dietary protein and that they might stimulate cancer with then could cause
rise in psa, specifically about men who are like me metastatic
castrate resistant and that decisions about if drugs being taken
are working is based a lot on psa - and to see if those certain
foods themselves might be some of the culprit in stimulating the cancer that
then causes psa to rise ?

Please don't include any pointers to or discussions of studies
that do or do not show how certain foods, ie eggs, dairy, whey protein,
chicken
might cause pca to spread and thus result in psa rise -
just interested in your own experiences please ! have read lots
of these studies before.

Also please don't suggest any other foods that might be better in helping to
add protein to one's diet than
the ones am discussing - I know all that but due to IBS and other issues,
cannot eat them. including dairy like yogurt or cheese.

Finally, am not interested if these certain foods can contribute
to causing cancer - I already got it re mcrpc status - and have
not had those foods for over 30 years in any case.


Why am I asking ?

My protein and albumin is low, and thus more is needed both during this
time being on desparate 2nd line medications, but also if infusion
chemo would happen - these levels are very, very important doctors tell me.

and due to my ibs issues, many, many foods, including many protein
sources cannot be eaten. That is, soy, red meat, cheese, and many
others.

Also, I need to get the biggest bang for the buck as to protein -
that is, 1 scoop of some whey protein has 24 gm of protein
whereas 1 jumbo egg, for example, has only 8 and 1.5 oz of chicken,
has about 8.

And will not and would not eat multiple eggs or amts of chicken daily
since would take lots of eggs or chicken to get to goal of 50 gm
or more of protein a day, esp if those foods could indeed lead to further
spread of pca which could lead to psa rise.

And can't eat any other stuff that might have protein in large amount.


But it was fun to have for first time in 30 years, an egg the other day,
but alas have had to give up so much food over the years that was easy to let that
go for now.

And until I find out if eggs, whey or chicken might contribute
to pca and thus could cause higher psa, won't even eat eggs.


As for the whey protein powder, will wait for your feedback before
even experiementing with it, that is will then try 1/3 scoop and wait
3 days, since with my ibs history, bad stuff can happen up to
3 days after injesting things ! And then see how it goes.

===> Thus, in your experiences taking whey protein powder,
and/or eating eggs or lean plain chicken,

--- did you find your psa going up from that (or rather that the foods
might have stimulated the cancer and psa went up from that) ?

again, goal here is not wanting to have psa go up for any reason other than
pca rx not working and/or further spread of pca - thats bad enough.

especially since psa levels can reflect if rx is working or not
and treatment decisions could be made based on it, ie stop the rx,
even though the cause of the psa rise might be just eating some
of these items, vs that rx really not working !

Unfortunately, individual experiences with food and psa can't be very instructive. I quit eating dairy, eggs and red meat after my PCa came back after surgery. Then I had radiation, and my psa has stayed undetectable for 2.5 years. I have no idea whether my diet has had any impact because I can't know what would have happened if I had been eating all those foods still. The experience of cashlessclay with diet and PCa has been described and discussed on this forum and is very interesting. He has been sticking with a very restrictive diet and his psa has stayed quite low despite having a case of advanced PCa. It seems to be working for him, but there is no proof that other people would have similar results.

this is OP - thanks to all so far for the info.

for me, Lupron failed after 2 yrs; started zytiga which probably has failed since psa went way up
while taking it - been about 3 months - after all studies say that it like any rx, might not work at all
or might work for a short time - and although for some folks it works longer, studies say that is
not a common case at all.

so dr is giving it one more try to see if it brings psa down or not

and after zytiga would perhaps be desperate attempt with xtandi or other such rx

but then would move to chemo -- and for that one needs to have good protein/albumin levels
which I need even now

so that's why posted this - since if during this time still on zytiga I would start adding protein
sources that might stimulate pca which then would cause psa to rise even more than it is rising -
that could mask effectiveness of zytiga - and perhaps be enough to tip the data to conclusion that its not working even if that tipping point might have been caused by dietary stuff that caused pca to increase and then that caused psa to increase.

so I guess staying off all these new proteins that I might try, that have controversial results in studies if they do or do not cause pca to grow more (and given all the rest of ok protiens that I cant try due to ibs)
-- until I know for sure zytiga is not working - perhaps that's the best way to go ? I don't think
it will be long until knowing that, alas.

as to "we still have arrows in the quiver" of other rx to try that people/drs often say - I don't think its meaningful to put any hopes
in that stuff - I know the path am on as to advanced pca and know alas where that it going -
just like it has gone for so many of us. of course will probably try some of that other stuff I guess …

thanks for allowing me to re-clarify why I posted this - and wish I could be more succinct and more positive !

Hello TomHW,

I know you are walking down some challenging roads. I'm mindful of you.

I like your thoughts about the "arrows left in the quiver" ...

Just when I needed help the most, some of my toughest treatments helped me the most.

Stay connected to your medical team. Rely on the expertise of your doctors ...

Often, I ask my doctors what the "next steps" will be. It helped me mentally prepare, in advance, for treatments that I have needed. No matter what treatments you might pursue in the future, we have members here who have experiences to share.

Keep forging ahead, TomHW.

Stay strong ---keep looking forward,
