Explain what is meant by metastasis.

(N/A) Metastasis is a characteristic property of malignant tumors. It is the pathological process by which cancerous cells spread from the primary site to other parts of the body. In this process,some cells from the tumor get detached and enter the bloodstream or lymphatic system. Through these circulatory systems,the cells reach distant organs,where they settle and divide uncontrollably to initiate the formation of new tumors,a process known as secondary tumor formation.
