Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
This editorial highlights the connection between what youngsters eat and drink (and those not so young) and its connection with breast cancer incidence. This is important data and again puts breast cancer under the spotlight, but is it not reminiscent of the episode in Fawlty Towers where Basil is serving a German group of tourists, and agrees with Manuel to absolutely not talk about "the war"! The war in the case of breast cancer is not diet or alcohol or any other possible spurious correlation you concoct with increasing breast cancer incidence in women, but female intake of exogenous hormones as HRT or contraception. The raw data is available on cancer sites, the demography of contraceptive using countries shows without fail that the more the contraceptive use, the less the birthrate, and the more of breast cancer. The two graphs in the Western world over the last 50 years are those of declining birthrates and increasing breast cancer. The driver of the graphs is not diet or alcohol - for one reason because they do not reduce birthrate- but exogenous female hormone use which does reduce birthrate and does cause cancer, it is classed as a category 1 carcinogen.
I wrote a short book called The Screech Owls of Breast Cancer which tries to show the obvious connection between female hormones and breast cancer.
