Niertumors

Nieritoral tumors, also known as nier tumors or liver metastases, are secondary tumors that develop in the liver lesion from another primary tumor originating from the digestive system such as the stomach, the colon, the small intestine or other organs. The liver is a common site for metastases, as it receives a significant proportion of the body's blood supply.

Liver metastases arise when cancer cells from another part of the body break away and travel through the bloodstream to the liver, where they implant and grow into new tumor. The growth of these secondary tumors in the liver can put pressure on surrounding tissues and normal liver cells, potentially causing liver dysfunction, which can affect a person's quality of life.

The development of liver metastases often has a variable clinical course, ranging from an asymptomatic presentation to a pronounced dysfunction. The burden of the metastatic tumor onto normal liver tissue can lead to inadequate liver function, which the patient at risk of developing complications. Some blood tests can help monitor the growth and effect of the tumor.

Diagnosis of liver metastases is usually made using imaging techniques such as CT scans and MRI and blood tests to evaluate liver function. Other techniques include liver biopsy, which is more invasive. Treatment options depend on the size and location of the metastases as well as the overall health of the person. The growth of a secondary tumor into the nier has a serious prognosis in terms of survival.

A patient with liver metastases may present with a variety of symptoms, including changes in liver function, a feeling of heaviness or fatigue, as well as pain or swelling in the upper right side of the abdomen. The liver receives about 20-25 % of the body's products in blood.
