>I agree that it is very frustrating never to hear anything about the published studies showing both that breastfeeding protects a mother against breast cancer and that having been breastfed protects children against cancer in general and breast cancer (in daughters) specifically. If anyone needs those references, I can provide them easily. There is a chapter on bf and cancer in my new book (sorry I always seem to be hyping my book) by Marc Micozzi of the National Museum of Medicine. He started out very skeptical about the issue and became a "convert" as he did his research and writing of the chapter. He has an MD as well as a Ph.D. in Anthropology, so maybe his credentials will lend credibility to his chapter as far as doctors are concerned. I gave my local ob/gyn a copy of the recent studies on bf and cancer and his response was "Well, the medical community doesn't accept these data." He wouldn't or couldn't explain what the heck that meant! I have a talk I give to classes and community groups on bf and breast cancer. Maybe each of you who are lactation consultants can schedule public talks during breast cancer awareness month (October I think) and try to get the word out. One of my overheads shows a time-line of decades from 1900 to 2000, and suggests that the rising breast cancer incidence rates can be traced to the fact that there were three sloppily overlapping cohorts of women: (1) those like my mother, born in the early decades of the century, who were both breastfed as children and breastfed their own children born in the 1930s and 1940s [actually my mother was born in 1920 and breastfed her children born in 1948 and 1955 (me) but bottlefed the middle one born in 1953 (which explains a LOT, we also joke). After bottle-feeding one in 1953, she switched back to breastfeeding with me in 1955 even though it wasn't the cool thing to do at the time.], (2) those born in the 1920s, 1930s, and 1940s, who were breastfed as children but did NOT breasfeed their own children born in the 1950s and 1960s (thereby losing the second source of protection), and (3) those born in the 1950s and 1960s who both were NOT breastfed and did NOT breastfeed their own children (thereby losing both the first and second sources of protection). The relationship can't be expected to be exact, because all along their were some women who breastfed even when it wasn't cool, and because women breastfeed for different lengths of time and for different numbers of children. Thus, I'm sure there is no way to prove that the recent rapid rise in breast cancer is due to the aging of the cohort that was neither breastfed nor did breastfeed their own children, but it is an interesting thought, and gets people talking. I'd love to hear what the rest of you think. When I showed my overhead explaining this to the above-mentioned ob/gyn he said "Hmmmmm. Interesting." ---------------------------------------------------------------------------- ------- Katherine A.
