Alcohol Cancer Lawsuit Investigation [2025 Update]

The Link Between Alcohol Consumption and Cancer

​The consumption of alcoholic drinks has been conclusively linked to an increased risk of developing various cancers.

The National Cancer Institute reports that drinking alcohol increases the likelihood of cancers such as those of the mouth, esophagus, pharynx, larynx, liver, and breast.

This elevated risk is attributed to the production of cancer-causing chemicals during alcohol metabolism, particularly acetaldehyde, which can damage DNA and proteins.

Even moderate alcohol consumption, defined as up to one drink per day for women and up to two for men, has been associated with a heightened risk of certain cancers.

Combining alcohol with tobacco use, specifically cigarette smoking, amplifies these health effects, further increasing the chances of developing cancer.

Given these findings, reducing alcohol intake is a crucial component of cancer prevention strategies.

Public awareness campaigns and updated warning labels on alcoholic beverages are among the measures being considered to inform consumers about these risks.

Individuals are encouraged to assess their drinking habits and make informed decisions to mitigate their cancer risk.

What Types of Cancer are Linked to Alcohol Consumption?

Studies have confirmed that alcohol use increases the likelihood of developing several types of cancer, with the National Cancer Institute and Surgeon General warning that no level of consumption is entirely safe.

Research shows that the cancer risk alcohol consumption poses is not limited to heavy drinkers—non-drinkers have a significantly lower risk compared to those who consume alcohol regularly.

One of the most well-documented risks is breast cancer risk, with studies indicating that even low to moderate drinking raises the chances of developing the disease.

Additionally, alcohol has been linked to breast cancer recurrence, meaning individuals who have already had breast cancer face heightened risks if they continue drinking.

Beyond breast cancer, alcohol consumption is associated with multiple other cancers, affecting key organs and structures in the body.

Types of cancer potentially linked to alcohol consumption include the following:

• Colorectal cancer – Studies indicate that even moderate alcohol consumption raises the likelihood of colorectal cancer.
• Breast cancer – Drinking alcohol increases breast cancer risk, and for survivors, it can also elevate the likelihood of breast cancer recurrence.
• Oral cavity and throat cancer – Alcohol damages the cells in the oral cavity, increasing the risk of mouth, pharynx, and voice box cancer.
• Esophageal cancer – Esophageal cancer has been strongly linked to alcohol use, especially among those with a genetic inability to properly metabolize alcohol.
• Liver cancer – Chronic alcohol consumption leads to cirrhosis, which significantly increases the risk of liver cancer.
• Laryngeal cancer: Alcohol consumption is linked to cancer of the larynx (voice box). ​
• Stomach cancer: Heavy alcohol consumption has been associated with an increased risk of stomach cancer.
• Ovarian cancer: Some studies have indicated a potential link between alcohol intake and ovarian cancer. ​

It’s important to note that the risk of developing these cancers increases with the amount and frequency of alcohol consumption.

Even moderate drinking has been associated with a higher risk of certain cancers, emphasizing the importance of being aware of these potential health risks.​

How Does Alcohol Use Cause Cancer?

Alcohol consumption increases the risk of cancer through multiple biological mechanisms, particularly when excessive alcohol use occurs over a prolonged period.

When the body metabolizes alcohol, it converts ethanol into acetaldehyde, a toxic compound that can damage DNA and proteins, leading to cancerous mutations.

Drinking too much alcohol also generates oxidative stress, which further harms cells and weakens the body’s ability to repair DNA damage.

Over time, this damage accumulates, increasing the likelihood of cancer in vital organs such as the liver, esophagus, and colon.

Studies show that even moderate alcohol consumption throughout adult life raises the risk of certain cancers, including breast and colorectal cancer.

Given these carcinogenic risks, health organizations are pushing for increased awareness and updated warning labels on alcoholic beverages.

About the Surgeon General's Warning on Alcohol and Cancer Risk

In January 2025, U.S. Surgeon General Dr. Vivek Murthy issued a pivotal advisory highlighting the significant link between alcohol consumption and cancer risk.

This announcement underscored that alcohol is the third leading preventable cause of cancer in the United States, responsible for approximately 100,000 cancer cases and 20,000 cancer deaths annually. ​

Since 1989, U.S. alcoholic beverage labels have included warnings about risks such as impaired driving and consumption during pregnancy, as mandated by the Alcoholic Beverage Labeling Act of 1988.

However, these labels do not specifically address cancer risks.

Dr. Murthy’s advisory advocates for updating these warnings to inform consumers about the carcinogenic potential of alcohol, aligning with practices in countries like Ireland, which plans to implement such warnings by 2026.

Despite the established risks, public awareness remains alarmingly low.

Surveys indicate that only about 45% of Americans recognize alcohol as a cancer risk factor.

This gap in knowledge contributes to misconceptions about the safety of moderate drinking.

Recent studies have debunked the notion that moderate alcohol consumption offers health benefits, emphasizing that even low levels of intake can increase cancer risk.

The advisory highlights that alcohol consumption elevates the risk for at least seven types of cancer, including breast, liver, and colorectal cancers.

The carcinogenic effects are primarily attributed to ethanol, which metabolizes into acetaldehyde—a toxic compound that can damage DNA and proteins, leading to mutations that may result in cancer. ​

Dr. Murthy recommends not only updating warning labels but also reassessing current guidelines on alcohol consumption limits.

The advisory suggests that existing recommendations may not adequately reflect the cancer risks associated with alcohol.

The alcohol industry has expressed concerns over these proposed changes, citing potential impacts on consumer behavior and sales.

Organizations like the Distilled Spirits Council of the United States argue that moderate drinking is associated with lower overall mortality rates, though these claims are increasingly challenged by recent research.

What is the Alcohol and Cancer Lawsuit Investigation?

The Alcohol and Cancer Lawsuit Investigation examines whether alcohol manufacturers failed to properly warn consumers about the cancer risks associated with drinking.

Scientific research has shown that alcohol increases the risk of multiple cancers, including breast, liver, and colorectal cancer, yet most alcoholic beverage labels do not disclose these dangers.

Lawsuits may be investigated to determine if companies knowingly withheld critical health information while marketing alcohol as a relatively safe product.

Studies have identified harmful chemicals like acetaldehyde, a toxic byproduct of alcohol metabolism, which damages DNA and contributes to cancer development.

In the event of litigation, plaintiffs may argue that consumers were misled about the long-term health consequences of drinking alcohol.

Legal investigations could lead to new labeling regulations, public health campaigns, and financial compensation for individuals affected by alcohol-related cancers.

As more evidence emerges, experts are assessing the viability of claims against alcohol manufacturers and industry groups.

As we’ve mentioned, there is NOT an active Alcohol Cancer Lawsuit.

TorHoerman Law: Experienced Personal Injury Attorneys

Research has confirmed that alcohol increases the risk of several cancers, yet consumers were not adequately warned about these dangers.

Potential lawsuits would address the fact that companies that manufacture and market alcoholic beverages may have failed to disclose the harmful chemicals produced when alcohol is metabolized.

Legal action has not been taken against major alcohol manufacturers related to these risks.
