Alcohol Use and Breast Cancer: A Critical Review

Abstract

The objective of this study was to outline the biological pathways of alcohol‐attributable breast cancer, the epidemiological risk relationship between alcohol consumption and breast cancer, and the global burden of breast cancer incidence and mortality attributable to alcohol consumption, with a focus on light drinking. First, the literature regarding the biological mechanisms of how alcohol affects the risk of breast cancer was reviewed and summarized. Second, a search of meta‐analyses that evaluated the risk relationship between alcohol consumption and breast cancer was conducted. Last, the burden of alcohol‐attributable breast cancer incidence and mortality was estimated by means of a Population‐Attributable Fraction methodology. Data on alcohol consumption were obtained from the Global Information System on Alcohol and Health, and data on cancer incidence and mortality were obtained from the GLOBOCAN database. Alcohol consumption affects breast cancer risk through the alteration in hormone levels and the associated biological pathways, the metabolism of ethanol resulting in carcinogens, and the inhibition of the one carbon metabolism pathway. The systematic review found 15 meta‐analyses on the risk relationship between alcohol consumption (also light consumption) and the risk of breast cancer. All but 2 of these analyses showed a dose–response relationship between alcohol consumption and the risk of breast cancer. An estimated 144,000 (95% confidence interval [CI]: 88,000 to 200,000) breast cancer cases and 38,000 (95% CI: 2,400 to 53,000) breast cancer deaths globally in 2012 were attributable to alcohol, with 18.8% of these cases and 17.5% of these deaths affecting women who were light alcohol consumers. All levels of evidence showed a risk relationship between alcohol consumption and the risk of breast cancer, even at low levels of consumption. Due to this strong relationship, and to the amount of alcohol consumed globally, the incidence of and mortality from alcohol‐attributable breast cancer is large.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • There is currently not enough epidemiological evidence to assess if the pattern of alcohol consumption modifies the risk of breast cancer.

    “there is currently not enough epidemiological evidence to assess if the pattern of alcohol consumption modifies the risk of breast cancer 151.”
  • Alcohol may alter one carbon metabolism by inhibiting folate absorption and folate cycle enzymes, leading to increased homocysteine concentrations.

    “First, alcohol may alter the one carbon metabolism by inhibiting folate absorption, leading to increased homocysteine concentrations 150, 151, and by inhibiting folate cycle enzyme methionine synthase and the trans‐methylation enzymes methionine adenosyltransferase and DNA methyltransferase 150, 152.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
