Breast cancer is the second most common cancer among American women, only surpassed by skin cancer, with nearly a quarter-million women being diagnosed each year in the United States.1
While many of the factors that increase a woman’s risk of developing breast cancer are out of her control (e.g., age and genetic makeup), some are in her control and may help to minimize risk. One of these risk factors for breast cancer is alcohol consumption.2
Moderate alcohol consumption has been linked with an increased risk of many types of cancer in women, including breast cancer.3,4 A woman can increase her risk of getting breast cancer by as much as 50% by having just 1–2 drinks per day. Higher alcohol intake appears to be correlated with an even further increase in breast cancer risk (about a 7% increase with every additional 10 grams consumed).4
Men also get breast cancer, but instances are rare, with less than 1% of breast cancers occurring in men. Research on male breast cancer has indicated, however, that rates of the condition are on the rise, with potential links being associated with genetics, obesity, and liver cirrhosis from excess alcohol consumption.5
A study published in the peer-reviewed journal Women’s Health looked at the possible mechanisms that explain how breast cancer risk is affected by alcohol consumption. Researchers studied factors such as the age of the onset of menstruation and the age of first pregnancies, along with rates of alcohol consumption in younger years and other breast cancer risk factors.6
They concluded that exposure to alcohol between the time of first menstruation and first pregnancy, which contributes to structural alterations in cells or tissues in the breast that may predispose it to breast cancer development. The risk increases with the duration of time between first menstruation and first pregnancy.6
Researchers also found evidence to support that the consumption of alcohol during adolescence and early adulthood (a time in which binge drinking is very common) may contribute to the increased risk. Binge drinking itself also appears to be a risk factor, with women who binge drink during the weekend but avoid alcohol during the week having a higher breast cancer risk than women who drink moderately throughout the week.6
The type of alcohol a woman drinks may also influence her risk. For example, red wine may contain anticancer properties, and its consumption may be linked to a lower risk of mammographic density than beer or white wine.6 Mammographic density is associated with a higher probability of developing breast cancer.7
Furthermore, alcohol intake contributes to breast cancer risk through its ability to increase levels of estrogen production indirectly in both premenopausal and postmenopausal women.6
You may not be able to change some of the genetic risk factors for breast cancer, such as the presence of the BRCA1 and BRCA2 genes or your own family history of cancer. However, you can make some lifestyle changes that may lower your overall risk of breast cancer:2
Staying healthy in all areas of your life will reduce your overall cancer risk, and it will increase the likelihood that you will survive if cancer does develop.2 Early detection is associated with better outcomes,8 so do not hesitate to get any potential symptoms checked out by your doctor so you have the best possible chance of recovery from breast cancer.
Being aware of the signs and symptoms of breast cancer allows you to check for any concerning changes and ask your doctor about them. You can conduct a breast self-exam regularly to monitor for changes in your breast. Concerning changes to look for include:1
If you notice any of these warning signs, see your doctor right away for further examination and diagnosis. Women between 50 and 74 years old should be having mammograms every 2 years, while women between 40 and 50 can talk to their doctors about recommended screenings.1
