Answer: Cancer cells can spread by growing into the surrounding blood vessels or lymphatic channels and then circulating to the lymph nodes in the region or beyond to vital organs, such as the liver or lungs. Some experts have estimated that less than one cell in a million can survive long enough to help form a metastatic tumor. Cells that do survive begin the growth of another tumor. Sometimes, the tumor cells fall or move to a nearby structure. This occurs most commonly in certain abdominal cancers, such as ovarian cancer or cancer of the appendix. Cells that break off an ovarian tumor may form sheets of cells along the lining of the abdominal cavity and grow on another organ in the abdomen, such as the bladder or the outside of the colon. This process is known as seeding.
