Sounds bad! But did you read the conclusion of the study: "We conclude
that soya consumption can affect hormones that regulate growth of
neoplastic cells, and that this may account at least in part for
decreased cancer risk in populations with high legume consumption."

Other studies have shown possible associative risks between soy
consumption and other forms of cancer. Indeed, some of the links I
offered note the higher incidence of esophegal and other alimentary
cancers in Asia -- thought to possibly be from a higher intake of soy.

So let us eat more soy!

No, let's do more research before we take ONE study and make unfounded
generalizations from it.
