Americans drink an average of about 2½ gallons of alcohol a year.

An analysis of 62 research studies says it’s not safe. The thread that runs through those previous studies is that alcohol is consistently tied to breast, colorectal and liver cancer.

Data from more than 100 million adults showed a breast cancer link in nearly 40% of all the studies, making it the most common cancer associated with drinking.

In the study, researchers from Florida Atlantic University, Case Western Reserve University and the Rutgers New Jersey Medical School’s emergency department found that beer, wine and liquor all showed cancer connections in multiple studies. So no type of drink is inherently safer than another.

Even a few drinks in a week showed an elevated risk of cancer, although heavier and more frequent drinking increased risk more.

The researchers noted that despite alcohol being classified as a Group 1 carcinogen, warning labels and public health messages rarely mention cancer risk.

Following breast cancer, colorectal cancer was the second most frequently identified cancer in 13 studies. Liver cancer appeared in 10.

The study revealed some interesting tidbits. Some studies found alcohol was associated with a reduced risk of glioma, a type of brain tumor, and multiple myeloma, a blood cancer.

The wealthier among us tend to drink more alcohol overall, but those with lower socioeconomic status face worse outcomes when they do, because of barriers like not having access to quality health care.

The researchers say Americans need straightforward information about the risks of alcohol. Without that, how can they decide if the next drink is worth it?
