Cancer cells can move to new locations in the body, a process called metastasis

Description
a Cancer cells break away from their original tissue. The metastasizing cells become attached to the wall of a blood vessel or lymph vessel. They secrete digestive enzymes to create an opening. Then they cross the wall at the breach. Cancer cells creep or tumble along inside blood vessels, then leave the bloodstream the same way they got in. They start new tumors in new tissues.
