The isothiocyanates and glucosinolates in moringa do have antitumor properties. The plant is also antiviral against some known cancer causing viruses such as Epstein Barr virus.
You are right, phytoestrogens are anticancer, not cancer promoting. If phytoestrogens were cancer forming then we would have trouble from eating plants since all plants we consume contain phytoestrogens or phytoestrogen-like compounds.
Glucosinolates are also found in cruciferous vegetables and are also known to have anti-estrogenic effects. Although, they are also goitrogenic. Therefore, it would be a good idea to take something like seaweeds with the moringa to counter the goitrogenic effects. Red seaweeds, such as dulse, are particularly antiviral and anticancer.
I just saw that you already replied to my question on whether He Shou Wu stimulates estrogen production in women in this older thread:

Not really. Again they are referring to phytoestrogens. Phytoestrogens do possess extremely weak estrogenic activity, but at the same time they antagonize real estrogens and the even stronger xenoestrogens. The estrogenic effect of he shou wu is 1/300th that of the body's estradiol.

It's good that I checked. So I guess your reply above also applies to my same question on Moringa, right?
Correct.
Thanks, Hv! Good to know that Moringa is useful against cancer.
I'm still wondering though. I see some sites mention that some herbs such as Moringa and He Shou Wu are "estrogenic", which I interpret to mean as a warning that these herbs can stimulate the body to produce more estrogen (estradiol). Is it really possible for these herbs to stimulate human estrogen production? If so, by what mechanism would that be?
Estrogenic refers to having a property of estrogen. What they are referring to is the fact that these plants contain compounds that have extremely weak estrogen-type effects. But this is also true of all the plants we eat including onions, garlic, peaches, parsley, yams, seaweeds, peas, rhubarb, etc.
