The extremely complicated processes that take place in detail during metastasis (Greek: emigration) have been researched in recent decades, but have still not been fully clarified. [[Epithelium]]ien are known to be the uppermost cell layer - the covering tissue - of the skin and mucous membrane tissue. They sit on a very firm membrane, the so-called [[basement membrane]], which is the first major obstacle for a cancer cell willing to emigrate. | The extremely complicated processes that take place in detail during metastasis (Greek: emigration) have been researched in recent decades, but have still not been fully clarified.

Absiedlungen von Tumorzellen, die über das Blut, die Lymphe und andere Ausbreitungswege zu anderen Gewebeorten gelangen und dort ihre zerstörerische Funktion entfalten.
The extremely complicated processes that take place in detail during metastasis (Greek: emigration) have been researched in recent decades, but have still not been fully clarified. Epitheliumien are known to be the uppermost cell layer - the covering tissue - of the skin and mucous membrane tissue. They sit on a very firm membrane, the so-called basement membrane, which is the first major obstacle for a cancer cell willing to emigrate.
To be able to move elsewhere, it must first break through the basement membrane. Then it must also penetrate the basal membrane of a vessel to enter its interior and be carried by the fluid in the vessel (blood or lymph). Later, it must adhere to a favorable site, again penetrate the vessel wall and the basement membrane, now to the outside, and - in order to settle and multiply at that site - form new blood vessels for its supply.
