Washington, 2 APR ( EFE).- eat soy may be a risk factor for some women who suffer from breast cancer can cause resistance to medications, according to a study presented today at the annual meeting of the American Association for cancer research (AACR).
The benefits of soy, a traditional vegetable in the East which has begun to be used as an additive in foods in the West, have been widely investigated, but this study, conducted by Robert Clarke and Leena Hilakivi-Clarke professors of Medical Center Oncology Georgetown Lombardi, analyzes a new perspective.
In particular, studied the reaction in laboratory rats between soy consumption and its response to tamoxifen, a drug that is usually applied after a primary breast cancer treatment to keep cancer “at Bay”.
The study, which divided rats into several groups, showed that those that had fed during his lifetime with soy or some component to include soy responded well to tamoxifen.
However, that began to consume soy in adult and after developing breast cancer, had a resistance to treatment response.
“these results suggest that Western women who initiated adult soy consumption must quit if they are diagnosed breast cancer,” said Dr. Leena Hilakivi-Clarke said in a statement.
Tamoxifen, which has been used for more than 20 years in the treatment of patients with breast cancer, is a drug in pill form that interferes with the activity of estrogen.
Is used as additional therapy after primary treatment for early stage breast cancer and prevention for women who have a high risk of developing this type of tumors.
