Question for the Docs here : how safe is Soy product

I was reading an article about soy product, the article said:

Soy is an excellent source of high quality protein and is low in artery clogging fat. It is also rich in important nutrients such as iron,zinc, and often calcium. However, the most serious side effect of soy is its potential to increase the risk of breast cancer in those who are predisposed. Any woman who has had breast cancer, or who is at risk, should discuss the pros and cons of soy with her physican.Soy also has been shown to interfere with thyroid function.

What does this tell us?_:mad:
