Even light drinking increases cancer risk: Study

Even one to two drinks per day can increase cancer risk, according to a top association of cancer doctors in the US. About 3.5% of cancer-related deaths and 5-6% of new cancer cases were due to alcohol consumption, a study by the American Society of Clinical Oncology (ASCO) said. Breast and colon cancers claim over 90,000 American lives each year, according to the Centers for Disease Control.
