Alcohol use is common and widely accepted, yet many are unaware of research proving its link to cancer. To address potential questions on this important topic, Red Door Community hosted an educational webinar featuring Erin Pelligrin, RD, LDN, Senior Director of Culinary Nutrition and Education of Unite for HER – a national nonprofit supporting cancer patients with integrative therapies and resources.
Erin presented the latest data in a clear, supportive manner, encouraging informed choices. Based on this presentation, we share these key findings and practical strategies for anyone seeking to understand the connection between alcohol and cancer.
The Science Is Clear
In 1987, the International Agency for Research on Cancer (IARC) classified alcohol as a Group 1 carcinogen—confirmed to cause cancer in humans.
The 2025 U.S. Surgeon General’s Advisory, Alcohol and Cancer Risk, emphasizes that this link has been well established since the late 1980s and has only grown stronger. Currently, alcohol is partially associated with at least seven types of cancer:
- Breast
- Mouth
- Throat (pharynx)
- Voice box (larynx)
- Esophagus
- Liver
- Colorectal
According to the World Health Organization, while higher alcohol consumption increases cancer risk, even low to moderate intake—as little as one drink per day—may raise the risk for certain cancers.
Alcohol and Cancer Treatment
For those undergoing cancer treatment, alcohol may interfere with therapy, weaken the immune system, worsen side effects, and interact with medications. Many oncologists recommend avoiding alcohol during and after treatment.
Making Informed Choices
Understanding the link between alcohol and cancer doesn’t mean making drastic changes overnight. Having an awareness of the facts will empower you to make decisions that align with your wellness goals. If you are considering a change in your alcohol consumption behaviors, consider these tips:
- Talk to your healthcare team about your personal situation
- Set alcohol-free days or weekly limits
- Choose non-alcoholic drinks at gatherings
