Is health info on wikipedia accurate?

http://en.wikipedia.org/wiki/Breast_cancer

I just read a Wikipedia article, "Breast Cancer," Wikipedia: The Free Encylopedia. March 22, 2009, http://en.wikipedia.org/wiki/Breast_cancer. I believe that this article is very helpful because it covers the basics facts of breast cancer. I know about these facts because my personal project is on this topic. I have been researching this topic since October.

One sentence from this article that stands out for me is: " Women in the United States have the highest incidence rates of breast cancer in the world; 141 among white women and 122 among African American women." I think that this is interesting because it involves the affect of race compared to the incidence rates of breast cancer.
