WHat's metastasis?

 

[Shuttaa]

Metastasis, or metastatic disease, is the spread of a disease from one organ or part to another non-adjacent organ or part. It had been previously thought that only malignant tumor cells and infections have the capacity to metastasize.
Some cancer cells acquire the ability to penetrate and infiltrate surrounding normal tissues in the local area, forming a new tumor. The newly formed "daughter" tumor in the adjacent site within the tissue is called a local metastasis[/color][/color]
