Intro:
Liver cancer, also known as hepatocellular carcinoma (HCC), is when tumor cells begin to grow out of control and eventually take over the liver’s healthy cells. Liver cancer can be divided into several categories: primary, secondary, and benign liver tumors. The primary causes include hepatitis B and C virus (HBV) (HCV), cirrhosis (a disease in which liver cells become damaged and are replaced by scar tissue), and alcohol consumption. Understanding liver cancer’s high-level statistics is crucial, as it can help individuals take preventive actions against the disease and recognize its early symptoms.
Incident Rate:
Liver cancer ranks as the 6th most common cancer worldwide. It is the 5th most common cancer in men and the 9th most common cancer in women. China, the United States, and Japan are the top three countries with the most incident rates. As of 2022, China has 367,657 diagnosed liver cancer patients, accounting for 42% of the world's total. The United States and Japan account for 5% and 4.7% of the global cases, respectively. As of 2024, 41,630 new cases have been reported worldwide.
Survival Rate:
The overall relative survival rate of liver cancers for people who are diagnosed for over 5 years or more is around 21.7%. The survival rate for localized stage (confined to Primary Site) liver cancer is 44%. The regional stage (spread to Regional Lymph Nodes) is estimated to be around 24%. The distant stage (cancer has metastasized) is around 20% of survival. If unknown, the survival rate is at its lowest of 12%.
