LOUISVILLE, Ky. (WDRB) -- Some people are in the midst of "Dry January" this month. 

The "Dry January" month challenges people to go the entire month without consuming alcohol. According to the National Institutes of Health, participants report better sleep, more energy and other improvements in their skin and hair.

Decreasing alcohol consumption can also improve overall health. A new report from the U.S. Surgeon General linked alcohol use to an increased risk for at least seven cancers including breast cancer. The study suggest daily drinks should be limited to one.

Dr. Jeffrey Hargis with Norton Cancer Institute said even a little bit of alcohol can increase a person's risk. Hargis said moderation is important.

"Even when you look at small amounts there is an increase risk of breast cancer and it increases so a little bit of alcohol on a daily basis is an increase but it is even higher if there is an excessive amount of drinking, two drinks a day, something like that," Hargis said.

The surgeon general's report also notes alcohol consumption is the third-leading preventable cause of cancer in the U.S. Patients who have a family history of obesity or breast cancer are also at a higher risk.
