Can soy help to prevent prostate cancer?
Question: I am a 61-year-old African-American diagnosed with prostate cancer about 2 years ago. I am currently on hormonal therapy and doing well after completing intensity modulated radiation therapy (IMRT). I have three brothers that I’m also concerned about. Do soy products help prevent or slow the progression of prostate cancer? Answer: There is some evidence that an increase in soy may decrease both the risk and recurrence rate of prostatic cancer. There is no direct evidence that a diet high in soy will slow the progression of known recurrent prostate cancer.
