Alcohol Use and Cancer Risk

According to the Centers for Disease Control and Prevention (CDC), the consumption of alcohol is associated with increased risk of developing more than ten different types of cancers.

When we drink alcohol, our bodies break it down into a substance called acetaldehyde. This substance can cause damage to our DNA, which is like the instruction manual for our cells. When DNA gets damaged, cells can start growing out of control, potentially leading to cancer.

The correlation between alcohol and cancer underscores the importance of moderating alcohol intake. The CDC highlights several types of cancer where alcohol consumption significantly elevates risk, including cancers of the mouth, throat, voice box, esophagus, colon, rectum, liver, and breast (in women). Studies indicate that consuming three or more alcoholic drinks per day heightens the risk of stomach and pancreatic cancers. Even prostate cancer has shown associations with alcohol consumption.

All forms of alcoholic beverages—whether wine, beer, or liquor—contribute to this heightened risk. The quantity consumed directly correlates with the risk level, emphasizing the importance of moderation in alcohol consumption.

The 2020–2025 Dietary Guidelines for Americans advocate for responsible alcohol consumption. Adults of legal drinking age are advised to either abstain from alcohol or limit intake to two drinks or less per day for men and one drink or less per day for women. The guidelines strongly advise against alcohol consumption for individuals under the legal drinking age, pregnant women, those with health conditions made worse by alcohol, individuals engaging in activities such as driving, and those recovering from alcohol use disorders.

November is Stomach and Pancreatic Cancer Awareness Month

Alcohol use can increase the risk of stomach (gastric) cancer and pancreatic cancer. Early detection is key, yet both cancers are often difficult to diagnose in early stages because symptoms may be mild or easily mistaken for other conditions. Knowing the warning signs can help you act sooner.

Possible symptoms of stomach cancer may include:

  • Ongoing stomach pain or discomfort

  • Heartburn or indigestion that doesn’t go away

  • Feeling full after eating only a small amount

  • Nausea or vomiting

  • Unexplained weight loss

  • Fatigue or weakness

  • Blood in vomit or stool (which may appear dark or tar-like)

Possible symptoms of pancreatic cancer may include:

  • Belly or back pain that doesn’t improve

  • Jaundice (yellowing of the skin or eyes)

  • Loss of appetite or unplanned weight loss

  • Changes in stool, such as greasy, floating, or pale stools

  • Nausea or vomiting

  • New diagnosis of diabetes or sudden difficulty managing diabetes

These symptoms can be caused by many other health issues, but if you notice any of them—especially if they persist—it's important to contact your health care provider. Early conversation and screening can make a difference.
