The spread of a tumor regionally to lymph nodes by the lymphatic system or to separate organs via the blood stream
If cancer cells get into the lymphatic system or bloodstream they may travel to other parts of the body and start growing there These cancers are called secondary cancers or metastases
The transference of a bodily function or disease to another part of the body, specifically the development of a secondary area of disease remote from the original site, as with some cancers
1963: Stayed in her own house, searched her body each morning and examined her conscience each night for progressive symptoms of the metastasis she feared was in her. — Thomas Pynchon, V.
A "secondary" tumor that is in a location remote from the original "primary" tumor Cancer cells often escape from the primary tumor and take up residence in distant parts of the body such as the lungs, liver, bones, or brain These escaped cancer cells can multiply so that new tumors form at these secondary locations Metastasis can also refer to the process by which metastases form A cancer which has spread is said to be metastatic
{i} transference of disease producing organisms from one part of the body to another via blood vessels (Pathology); rapid change from one subject to another (Rhetoric); change in position or orbit of an elementary particle (Physics)
the tranferrence of a bodily function or disease to another part of the body, specifically the development of a secondary area of disease remote from the original site, as with some cancers
The act or process by which matter is taken up by cells or tissues and is transformed into other matter; in plants, the act or process by which are produced all of those chemical changes in the constituents of the plant which are not accompanied by a production of organic matter; metabolism
The spread of cancer from one part of the body to another Metastasis is the word used for a new tumour caused by the spread of cancer cells from the original site in the body
"The spread of cancer from one part of the body to another Tumors formed from cells that have spread are called""secondary tumors"" and contain cells that are like those in the original (primary) tumor The plural is metastases " SOURCE : http: //cancernet nci nih gov/dictionary html
—The spreading of a cancerous tumor to another part of the body through the lymph, blood, or across a cavity; also sometimes refers to a tumor that has been produced in this way
When a cell or clump of cells separates from a tumor and spreads to another location, it is said to have metastasized Metastasis is one of the main reasons some tumors are difficult to control
n (meh-TA-sta-sis) Transfer of disease from one organ or part to another not directly connected with it It may be due either to the transfer of pathogenic microorganisms (for example, tubercle bacilli) or to transfer of cells, as in malignant tumors The capacity to metastasize is a characteristic of all malignant tumors
