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.
Given that several liver tumors appear similarly on these imaging modalities, a multi-phase contrast-enhanced imaging study such as CT or MRI may be used to provide more information. [ 3 ] [ 4 ] The significance of making a specific diagnosis is that, unlike other benign liver tumors such as hemangioma and focal nodular hyperplasia, hepatic ...
A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.
Liver tumor types by relative incidence in adults in the United States (liver cancers in dark red color). [14] The most frequent liver cancer, accounting for approximately 75% of all primary liver cancers, is hepatocellular carcinoma (HCC). [15] HCC is a cancer formed by liver cells, known as hepatocytes, that become malignant. In terms of ...
In the overwhelming majority of cases, liver spots pose no threat and require no treatment, though they occasionally have been known to obscure the detection of skin cancer. However, despite being a benign condition, liver spots are sometimes considered unsightly and some people choose to have them removed.
Focal nodular hyperplasia is a benign tumor of the liver (hepatic tumor), which is the second most prevalent tumor of the liver after hepatic hemangioma. [1] It is usually asymptomatic, rarely grows or bleeds, and has no malignant potential. [2]
Pre-cancerous, or pre-malignant tumours, are not cancerous but can develop to be so and therefore it is important for doctors to monitor these tumours closely. Several kinds of benign tumour can ...
Surgical removal of the tumor is associated with better cancer prognosis, but only 5–15% of patients are suitable for surgical resection due to the extent of disease or poor liver function. [58] Surgery is only considered if the entire tumor can be safely removed while preserving sufficient functional liver to maintain normal physiology.
