Liver tumour - the most common type of liver tumour is metastasis.
Other conditions affecting the liver (mainly the Stomach- and intestinal tract) tumours are 20 times more likely to metastasise than tumours originating primarily in the liver.
A Maydiseases can be diffuse, affecting the whole liver, and nodular, circumscribed diseases. A Maytumours are nodular diseases, distinguishing between benign and malignant lesions.
Benign tumours are very common: they occur more frequently in women, and most of them are associated with the use of contraceptives. The three most common benign lesions are haemangiomas, true hepatocellular tumours (adenomas) and focal nodular hyperplasia (a form of the liver containing its own tissue elements but in a different proportion to intact liver tissue).
Tumour-like lesions in the liver can be regenerative nodules, solitary or multiple cysts, echinococcal (parasitic) cysts, abscesses caused by infection, and haematomas caused by injury.
A Mayprimary malignancies include hepatocellular carcinoma and cholangiocellular carcinoma. Both diseases are usually diagnosed at an advanced stage due to their asymptomatic nature and therefore have a very poor prognosis.
