Soy, Phytoestrogens, and Breast Cancer

[Guest guest]

I have read controversial info about soy. The latest I read said something

along the lines of: " eat soy to *prevent* breast cancer, but if you are ever

diagnosed with breast cancer, stop eating soy. "

This makes no sense to me. Soy is a phytoestrogen. I would think, then, it

could " promote " an already-growing E+ tumor, correct?

And I think I read, too, that flax is also a phytoestrogen (lignan not

isoflavone) but do not quote me on that!

Can someone explain this confusion about soy and phytoestrogens? Thanks in

advance.

Here is a site that gives a list of natural estrogen containing foods.

Do we avoid all of them?

My Dr. said not to drink soy milk, but if you look in most food labels there is

soy, so what do you do, stop eating. I just eat less. Vicky

Is natural estrogen different from estrogen replacement pills??? If I'm triple

negagative, I can't have any hormone replacement.. so where does that lead me

with eating those foods!! I eat many of those just out of regular healthy

eating habits!!

YIKES

Michele,

I assume if you are triple negative that means you are er- which means

your cancer is not fueled by estrogen so, I can't see a problem with

you eating foods with natural estrogens in them. Of course best to

check with your doc. I am er+ so I try to avoid the xenoestrogens ie,

in plastic, pesticides, meats that have hormones and antibiotics in

them. I am really not too concerned about the natural estrogens in

various foods. I put out that list just to show that natural

estrogens are in a lot of the foods, that are good for us, and we

shouldn't go crazy avoiding them. It is easy to go too far in either

the conventional or alternative sense. I try to let my body be my

guide with a little research into various therapies.

My herbalist said not to flip out over this list. She

says eat around, without making a whole diet of any

one thing. The oncologist says soy is the big one to

watch out for. He says an occasional meal including

for example tofu (which was my favorite and which I

have dropped) is even okay; that what we do not want

to see is *steady levels* of estrogens going in. The

occasional spike is not worrisome according to this

one. He has ties to Hopkins so I'm assuming his

information is reasonably good.

Hope it helps.

My surgeon said not to eat soy nuts but the medical oncologist said

that it was ok to eat soy foods.

Thanks Ruth,

That made perfect sense!! I never thought of it that way, I was thinking of it

in a completely different aspect. Thanks for setting my mind straight and at

ease!

This is what the national cancer socity says: (in a nutshell - they

don't understand what's really going on, although it appears that

the estrogens from soy could link up to estrogen receptors on ER+

cells just as your body estrogen could).

http://www.cancer.org/docroot/NWS/content/NWS_1_1x_Soy_and_Breast_Can

cer.asp

I think their bottom line is just to try to keep as healthy as you

can. And remember - even this *reduces* risk, but doesn't make the

risk zero.

I would think it would be better for a weaker phytoestrogen to bind

with the estrogen receptors rather than the xenoestrogens in

pesticides, plastics and hormone enhanced meat. My personal opinion.

I avoid the xenoestrogens, where possible, and am judicious about the

phytoestrogens just because the jury is still out on them. The

current thinking seems to be (I will find the reference if anyone

would like it) that phytoestrogens consumed from adolesence to

perimenopause protect against breast cancer. However, consuming them

after menopause has no protective effect.
