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.
They can arise in several parts of the body, and thus form sub-types of diseases such as stomach cancer and pancreatic cancer. [ 1 ] [ 2 ] [ 3 ] The WHO defines "Hepatoid carcinoma" as "An adenocarcinoma with morphologic characteristics similar to hepatocellular carcinoma, arising from an anatomic site other than the liver".
Liver metastasis is the more common of the two liver cancers. [3] Instances of liver cancer are increasing globally. [8] [9] Primary liver cancer is globally the sixth-most frequent cancer and the fourth-leading cause of death from cancer. [7] [10] In 2018, it occurred in 841,000 people and resulted in 782,000 deaths globally. [7]
A neoplasm (/ ˈ n iː oʊ p l æ z əm, ˈ n iː ə-/) [1] [2] is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia . The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger ...
Some symptoms that are more closely associated with liver disease include yellow skin (also called jaundice), abdominal swelling due to fluid in the abdominal cavity, easy bruising from blood clotting abnormalities, loss of appetite, unintentional weight loss, abdominal pain, nausea, vomiting, or feeling tired.
Cancer of the stomach, also called gastric cancer, is the fourth-most-common type of cancer and the second-highest cause of cancer death globally. [2] Eastern Asia (China, Japan, Korea, Mongolia) is a high-risk area for gastric cancer, and North America, Australia, New Zealand and western and northern Africa are areas with low risk. [5]
Hyperplasia of parietal cells causes an abnormal release of HCl into the duodenum, which causes the ulcers of the duodenum. Excessive HCl production also causes hyperperistalsis, [ 14 ] a condition marked by excessive rapidity of the passage of food through the stomach and intestine and inhibits the activity of lipase , causing severe fatty ...
GISTs may present with trouble swallowing, gastrointestinal bleeding, or metastases (mainly in the liver). Intestinal obstruction is rare, due to the tumor's outward pattern of growth. Often, there is a history of vague abdominal pain or discomfort, and the tumor has become rather large by time the diagnosis is made.
