Alcohol Intake Increases Risk of Certain Breast Cancer Types

Posted in Alcoholism

Breast cancer detection can be an overwhelming thing for any female, regardless of age. What may prove even more shocking for some is the realization that actions of their own could have contributed to the condition.

In a recent Science Daily release, it was discovered that when alcohol intake increases, the individual is at a higher risk for certain types of  breast cancer. According to a study known as the Women’s Health Initiative (WHI) study, alcohol can increase the risk of lobular and hormone receptor-positive breast cancer. At the same time, it may not increase the risk of ductal carcinomas.

While alcohol has already been established as a potential risk factor for breast cancer in general, there are still few studies that are actually completed on the relationship between the use of alcohol and the risk of breast cancer according to subtypes. Very few studies actually examine whether the cancer is in the milk ducts or in the milk-producing lobules.

In the WHI study, researchers examined data from 2,944 women who had developed invasive breast cancer. Data was collected on these women that included the tumor subtypes, alcohol consumption, demographic and lifestyle characteristics, hormone status, family history of diseases and reproductive history.

Researchers determined that alcohol use has a strong relation in terms of the risk of lobular carcinoma, more so than ductal carcinoma. It is also more strongly related to breast cancer that is hormone-receptor-positive as opposed to hormone-receptor-negative.

Overall, those women who drank one or more drinks per day had doubled their risk of lobular breast cancer, the type that accounts for roughly 70 percent of all breast cancers diagnosed.
