Liver cancer is one of the fastest-growing causes of cancer-related deaths worldwide, and India is no exception. While genetics and environmental factors play a role, three major contributors consistently stand out: chronic alcohol consumption, hepatitis infections, and long-term liver damage. Understanding how these factors are interconnected is essential for early prevention, timely diagnosis, and effective treatment.
At Action Cancer Hospital, a leading Medical Oncology Hospital, specialists emphasize awareness as the first step toward reducing the burden of liver cancer. This blog explores how alcohol and hepatitis independently and collectively increase the risk of liver cancer, and what individuals can do to protect their liver health.
Liver cancer primarily refers to hepatocellular carcinoma (HCC), which originates in liver cells. In most cases, liver cancer does not develop suddenly. Instead, it evolves over years of chronic liver damage, inflammation, and scarring (cirrhosis).
The liver is a vital organ responsible for detoxifying harmful substances, metabolizing nutrients, and supporting immunity. When repeatedly injured—by alcohol, viruses, or toxins—the liver’s ability to regenerate becomes impaired, paving the way for cancerous changes.
Alcohol is processed almost entirely by the liver. Excessive and prolonged alcohol consumption overwhelms the liver’s detoxification process, leading to a range of liver diseases:
Each stage represents increasing liver damage. Cirrhosis, in particular, significantly raises the risk of liver cancer.
Alcohol breaks down into acetaldehyde, a toxic compound that damages DNA and prevents cells from repairing themselves. Chronic alcohol use also:
