Researchers analyzed information from almost half a million study participants and found that a person's risk of developing colorectal cancer increased when alcohol consumption increased.

Specifically, people who had more than two drinks a day were more likely to develop cancer of the colon or rectum than people who had fewer than two drinks a day. People who had more than three drinks a day were the most likely to develop colorectal cancer.

The study didn't find any relationship between colorectal cancer and types of drinks. This means that in general, the risk of developing cancer of the colon or rectum would increase whether someone drank two glasses of wine each night or two gin and tonics.

This study reinforces the idea that to minimize your risk of developing colorectal cancer, it's best to drink in moderation.
