'Self-seeding' of cancer cells may play a critical role in tumor progression

Cancer progression is commonly thought of as a process involving the growth of a primary tumor followed by metastasis, in which cancer cells leave the primary tumor and spread to distant organs. A new study shows that circulating tumor cells -- cancer cells that break away from a primary tumor and disseminate to other areas of the body -- can also return to and grow in their tumor of origin, a newly discovered process called "self-seeding."
