COMMENT A tumour formed by metastatic cancer cells is called a metastatic tumour or a metastasis. The process by which cancer cells spread to other parts of the body is also called metastasis.<BR>Metastatic cancer has the same name and the same type of cancer cells as the original, or primary, cancer. For example, breast cancer that spreads to the lung and forms a metastatic tumour is metastatic breast cancer, not lung cancer.
