What is the metastatic neoplasm?

Metastases are migrated malignancy. Metastatic neoplasm - also known as a metastatic tumor - is a cancer tumor whose cells migrated from the primary place of cancer to the secondary place. As a diagnosis is a metastatic neoplasm in the form of secondary cancer. The metastatic neoplasm consists of abnormal cellular growths of a neighboring organ or tumor cells that attacked the organs of the second place after passing either by blood or lymphatic networks. The discovery of the primary place of cancer sometimes requires a significant battery of tests. The primary place is a place in the human body, where cancer first developed. Metastatic neoplasm cells can be carefully examined for tracks in terms of make -up first cells, sometimes leading to the discovery of the primary place. In order to ensure that both places can be treated, primary should be discovered. Another possibility is that the only tumor cell can pass the lymph trunky or blood capillaries from the organ or tissues a distant area in the body. For example, some forms of metastatic neoplasms inThe brain comes from the tumor of the primary bladder.

Metastatic neoplasm, when he established himself in a secondary place, develops his own blood nets to collect nutrition from neighboring tissues and capillaries. Tumor cells that migrate blood capillaries are back into these blood capillaries or penetrate blood vessel membranes nearby to attack nutrition from blood to grow. As the neoplasm attacks near the blood vessels, it can store its own metastatic tumor cells in the bloodstream to migrate elsewhere.

Metastatic tumor cells that survive killer macrophages and white blood cells that constantly scan blood circulation for patients by microorganisms, often show migration from certain areas of organs to another specific organ area. Medical scientists, pathologists and oncologists have seen certain patterns in the behavior of these migrations that can help in localization of primaryof the places. There is a research of these topics. Sometimes the presence of indicators, such as these in metastatic neoplasms, point to specific organs to perform imaging tests for the location of primary places.
