The document discusses various liver problems including cancer, cysts, hepatitis, and fibrosis. Liver cancer begins in the liver cells and is one of the most common cancers worldwide. Symptoms of liver problems include weight loss, abdominal pain, and jaundice. Liver cysts are fluid-filled sacs in the liver that are usually benign, though large cysts can cause pain or infection. Hepatitis is liver inflammation that can be caused by viruses and results in jaundice, fatigue, and abdominal pain. Fibrosis occurs when scar tissue replaces healthy liver cells, preventing the liver from functioning properly and causing symptoms like abdominal pain and jaundice.
