Hello Barbara,
of all women, 6.3 percent will get breast cancer, or 63 of 1000 women.
If - through more breastfeeding - only 6 percent of all women will get
breast cancer, then 60 of 1000 women will get breast cancer.

Now you take those "6.3 percent of all women (63 of 1000)" as your new
"100 percent", that is, "all the women who get breast cancer now".
If 63 women are 100%, then 60 women are about 5% less.

>I was just reading the Lancet study someone posted here earlier this week and have a question.  It states in the final paragraphs, " The researchers also calculated what would happen to breast cancer risk if women still had only two or three children but breastfed each for six months longer....nine months per baby.
    They found that the chances of breast cancer would decrease from 6.3
percent to 6 percent, a 5 percent drop."

Unless my math is incorrect-as it may well be-6.3 percent to 6 percent
doesn't equal 5 percent.  Can someone clarify this for me?  I want to
pass
the article on and use pertinent facts in BF class.  Thanks.
