Strategies for Liver Cancer Prevention: Understanding Causes, Risks, and Preventive Measures
Liver cancer is a serious health concern, with approximately 25,000 males and 11,000 females developing the disease each year in the United States alone. To effectively reduce the risk of developing liver cancer, it is crucial to prevent and manage key risk factors such as hepatitis B and C infections, aflatoxin exposure, liver conditions, lifestyle factors, and to understand broader risk contributors.
Prevention and Treatment of Hepatitis B and C
Hepatitis B and C infections are leading causes of liver cancer. Vaccination is highly effective and recommended, especially for high-risk populations such as people with multiple sexual partners, injecting drug users, healthcare workers, and infants. Early vaccination provides long-term protection against hepatitis B[1][4]. Early detection of hepatitis B and C through screening enables timely antiviral treatment, reducing progression to chronic liver disease and liver cancer[3]. Practice safe sex, limit the number of sexual partners, use condoms, and avoid sharing needles to minimize transmission risk of hepatitis B and C viruses[1].
Reduce Exposure to Aflatoxin
Aflatoxins, carcinogens produced by certain molds, can contaminate food crops such as peanuts and grains. Limiting consumption of contaminated foods and improving food storage conditions help reduce exposure, especially in regions with high aflatoxin prevalence.
Screening and Treating Liver Conditions
Regular screening of individuals with chronic liver disease, including viral hepatitis, fatty liver disease, or cirrhosis, is essential to detect early liver cancer or precancerous liver conditions. Treat underlying liver diseases such as metabolic dysfunction-associated steatotic liver disease (MASLD, formerly NAFLD), alcohol-related liver damage, and chronic hepatitis to prevent cancer development[2][5].
Lifestyle Changes
Avoid tobacco use, as it is linked to many cancers, including liver cancer[1]. Limit alcohol consumption, as excessive alcohol intake is a major risk factor for liver damage and cancer[2][5]. Maintaining a healthy weight and engaging in regular exercise can help reduce the risk of liver cancer[1][2]. Eating nutrient-rich foods and avoiding processed/junk foods can support liver health[1][4].
Understanding Risk Factors
Major risk factors for liver cancer include chronic hepatitis B and C, aflatoxin exposure, excessive alcohol use, obesity/metabolic syndrome, and certain genetic or environmental factors. The global burden of liver cancer is rising due to population aging and growth, emphasizing the need for widespread preventive efforts[2][4].
Speaking with a healthcare professional about risk factors for liver cancer is recommended. A doctor can help a person determine the underlying cause of their symptoms and provide additional steps to reduce their risk of developing liver cancer. Some foods that can become contaminated by aflatoxin include cocoa, millet, maize, peanuts, rice, sesame seeds, spices, wheat, and fig. As liver cancer progresses, a person may experience symptoms such as nausea, swelling in the abdomen, and jaundice.
Certain infections and conditions that can increase a person's risk of liver cancer include hepatitis B and C, hepatitis D, non-alcoholic fatty liver disease, and cirrhosis. Maintaining a healthy diet and regular exercise can help reduce the risk of liver cancer for people with obesity. Smoking can cause liver cancer and quitting smoking is recommended. Excessive alcohol consumption can lead to cirrhosis, increasing the risk of liver cancer, and reducing alcohol intake is advised.
People of certain races and ethnicities, such as Asian Americans and Pacific Islanders, have higher rates of liver cancer. It is important to consult a doctor if unusual symptoms like jaundice, unexplained weight loss, fatigue, or pain in the back or near the right shoulder blade occur. By treating any underlying conditions, a person may help reduce their risk of developing liver cancer.
