Final answer:
Risk factors for hepatocellular carcinoma include chronic hepatitis B or C infection, alcohol abuse, and exposure to certain environmental toxins like aflatoxins.
Step-by-step explanation:
Some associated risk factors of hepatocellular carcinoma include, but are not limited to, chronic infections with hepatitis B or C viruses, excessive alcohol intake, and exposure to aflatoxins or other environmental toxins. Chronic hepatitis infection can lead to cirrhosis, which heavily predisposes individuals to developing liver cancer. Similarly, cirrhosis from excessive alcohol consumption or due to other causes such as Wilson's disease, which involves copper overload in the body, can also increase the risk of developing hepatocellular carcinoma.
