#574 - The Truth About Breast Cancer -- Part 4

چکیده
Late last month the NEW ENGLAND JOURNAL OF MEDICINE (NEJM) published a study (by David J. Hunter) comparing the levels of DDE and PCBs in the blood of two groups of women, one group with breast cancer, the other without.[1] The Hunter study failed to find a positive relationship between breast cancer and DDE or PCBs in the blood. DDE is a breakdown product of the organochlorine pesticide DDT, which was banned in the U.S. in the mid-1970s; PCBs are a group of 209 chlorinated industrial chemicals, also banned in the U.S. The Hunter study is the largest of its kind to date, comparing 236 pairs of women for DDE and 230 pairs for PCBs.

Having more babies is more protective against breast cancer --having more than 5 is most pr...
