Dr. Vineet Talwar, Director of Medical Oncology at RGCIRC, challenges the common belief that moderate drinking is harmless, asserting that there is no truly “safe” limit for alcohol consumption. He explains that alcohol is a potent carcinogen that triggers cancer development by producing acetaldehyde, a toxic chemical that damages DNA and prevents cells from repairing themselves. Dr. Talwar highlights that even occasional drinking increases the risk of various malignancies—specifically oral, liver, esophageal, and breast cancers—the latter of which is exacerbated by alcohol’s ability to raise estrogen levels. Ultimately, he stresses that the health risks are dose-dependent, meaning that while heavier drinking is more dangerous, the safest choice for cancer prevention is complete abstinence.
