While the role of alcohol consumption has been established as a risk factor for breast cancer, most of the research has focused the relationship on hormonally sensitive breast cancers.  A new study published in the Journal of the National Cancer Institute takes a look at the risk of alcohol and breast cancer subtype.  While the study reconfirmed a higher breast cancer risk from alcohol overall and a higher risk for hormone-receptor positive cancers, it found that the associated alcohol/breast cancer risk was observed in invasive lobular cancer but not for invasive ductal cancers.

This suggests a distinct etiology for these sub-types  of breast cancer and further research is needed.



Does normal intake of alchohol lead to breast cancer or by excessive consumption? Does it mean that one in 100 individual has a risk of breast through alcohol consumption?
