Hepatocellular Carcinoma (HCC) is a type of liver cancer that originates in the liver cells, known as hepatocytes. It is the most common form of primary liver cancer and often occurs in individuals with chronic liver diseases, such as cirrhosis or hepatitis B and C infections. Risk factors include heavy alcohol consumption, obesity, and exposure to certain toxins. Diagnosis of HCC typically involves imaging tests like ultrasound, CT scans, or MRI, along with blood tests to check for liver function and tumor markers. Treatment options may include surgery, liver transplantation, or targeted therapies, depending on the stage of the cancer and the overall health of the liver.
