Primary liver cancer is globally the sixth-most frequent cancer and the fourth-leading cause of death from cancer. [7] [10] In 2018, it occurred in 841,000 people and resulted in 782,000 deaths globally. [7] Higher rates of liver cancer occur where hepatitis B and C are common, including Asia and sub-Saharan Africa. [3]
Hepatocellular carcinoma in an individual who was hepatitis C positive. Autopsy specimen. Hepatocellular carcinoma (HCC[1]) is the most common type of primary liver cancer in adults and is currently the most common cause of death in people with cirrhosis. [2] HCC is the third leading cause of cancer-related deaths worldwide.
Liver tumor. Liver tumors (also known as hepatic tumors) are abnormal growth of liver cells on or in the liver. Several distinct types of tumors can develop in the liver because the liver is made up of various cell types. [1] Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths.
Alcohol causes cancers of the oesophagus, liver, breast, colon, oral cavity, rectum, pharynx, and larynx, and probably causes cancers of the pancreas. [ 2 ] [ 3 ] Cancer risk can occur even with light to moderate drinking.
However, liver and stomach cancer are primarily due to infectious causes. Liver cancer is largely caused by infectious hepatitis B virus (HBV) plus hepatitis C virus (HBC) and stomach cancer is largely caused by Helicobacter pylori bacteria. World-wide, the estimated number of people chronically infected with HBV and/or HCV is ~325 million. [8]
Cancer is caused by genetic changes leading to uncontrolled cell growth and tumor formation. The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1][2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4]
HCC occurs in about 85% of patients diagnosed with cirrhosis, and is the fourth leading cause of cancer-related mortality worldwide, according to U.S. government data.
Chronic (rather than acute) infection with hepatitis B virus or hepatitis C virus is the main cause of liver cancer. [60] Globally, about 248 million individuals are chronically infected with hepatitis B (with 843,724 in the U.S.), [61] and 142 million are chronically infected with hepatitis C [62] (with 2.7 million in the U.S.).
