Abstract
Hepatocellular carcinoma is one of the most common malignancies, responsible for over one million deaths annually worldwide. Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer accounting for 7.5% and 3.5 % of all cancers among men and women respectively. The disease is associated with environmental exposure to hepatitis B virus and hepatitis C virus. Cirrhosis is the most common association of HCC, being the underlying disease in 80%-90% of patients with primary liver cancer in most countries. Its high prevalence in Egypt is mainly due to the incidence of hepatitis C viral infection this is due to the mass anti-belharzial campaign therapy.
