Yes, we have a ways to go. The latest edition of Gofman's book makes it clear that the problem of excessive radiation of girls' and women's breasts is NOT a thing of the past. Anyone who wants to learn how to prevent breast cancer needs to know what Gofman is talking about so that they can protect themselves and their loved ones from excessive medical irradiation. In recent years, attention has focused on chemicals that can disrupt the hormone system. Often these chemicals mimic or block estrogen.
Some people think it is.
Some say not, arguing that organochlorines are 100 to 10,000 times less potent than natural hormones. Organochlorines are not necessarily bound in this way. Many organochlorines have half-lives measured in years. No one has suggested that chemical exposures explain ALL unexplained breast cancers. The possibility seems too important to ignore.
