In a nutshell

This study aimed to examine the effect alcohol consumption has on patients with breast cancer. This study concluded that low, moderate and high levels of alcohol intake were not associated with an increased chance of mortality as compared to non-drinkers.

Some background

Alcohol intake is a known risk factor for breast cancer incidence. The effect alcohol consumption has on patients who already have breast cancer is unclear. Some studies have noted an increase in mortality risk with high intake, while other studies have not found any significant effect.

Methods & findings

This study examines the effect alcohol consumption has on overall rate of deaths (mortality), mortality specific to breast cancer and non-breast cancer mortality. It included 1116 women with a family history of breast cancer and who also have breast cancer. Their average number of drinks taken per week was assessed. Low alcohol intake was considered 3 or less drinks per week. Moderate to high alcohol intake was more than 3 drinks per week.  

This study followed patients for 9 years and in this time there were 211 total deaths. Of these, 58 deaths were related to breast cancer. Low, moderate and high levels of alcohol intake were not associated with an increased chance of mortality as compared to non-drinkers.

The bottom line

This study concluded that low, moderate and high levels of alcohol intake were not associated with an increased chance of mortality as compared to non-drinkers.

The fine print

These patients are on a high risk breast cancer register due to family history. These results may not be applicable to all patients.
