Breast cancer soy study suggests increased tumor resistance

A new Georgetown University study suggests that eating high levels of soy may increase your chances of developing a breast cancer tumor that aggressively resist treatment.

The research, done by researchers from the Lombardi Comprehensive Cancer Center, shows that soy can make tumors resistant to certain drugs used to treat them, especially for women who started eating it later as adults.

Professors in the study have gone as far as to suggest that women stop ingesting soy if they're diagnosed with breast cancer.

"Since the jury is still out, I tell my patients with cancer to stay away from soy until definitive testing is in," Dr. Regina Hampton, whose practice is based in Lanham, said.

However, the Soyfoods Association of North America disputes the findings. They cite a 2009 American Medical Association study that showed just the opposite - that soy food decreased the risk of death and recurrence of breast cancer. They even said that at high levels, soy appeared to be as effective as tamoxifen, a drug used to treat cancerous tumors.
