What is metastasis?

ANSWER

Cancers continue to grow and spread by direct extension or through a process called metastasis, whereby the malignant cells travel through the lymphatic or blood vessels -- eventually forming new tumors in other parts of the body.

The term "cancer" encompasses more than 100 diseases affecting nearly every part of the body, and all are potentially life-threatening.
