Alcohol consumption has recently been linked to which condition?

• A. Alzheimer's
• B. Parkinson's
• C. Cancer
• D. Diabetes

Answer: (C)

Alcohol use increases cancer risk because ethanol is broken down into acetaldehyde, a toxic compound that can damage DNA and proteins. This, along with the generation of reactive oxygen species and a dampened immune response, helps abnormal cells to grow into cancers. The tissues most exposed to alcohol—such as the mouth, throat, esophagus, liver, colon, and breast—show higher cancer risk as drinking increases, and the risk climbs with more consumption. While alcohol can impact brain health and other conditions, the cancer connection is the most consistently observed in recent research, making it the best answer here. Diabetes risk with alcohol is more complex and influenced by many factors, so it’s not as direct a cancer-related link.
