Detailed explanation-1: -Cancer that spreads from where it started to a distant part of the body is called metastatic cancer. For many types of cancer, it is also called stage IV (4) cancer. The process by which cancer cells spread to other parts of the body is called metastasis.

Detailed explanation-2: -Metastasis. In metastasis, cancer cells break away from where they first formed (primary cancer), travel through the blood or lymph system, and form new tumors (metastatic tumors) in other parts of the body.

Detailed explanation-3: -(meh-TAS-tuh-size) To spread from one part of the body to another. When cancer cells metastasize and form secondary tumors, the cells in the metastatic tumor are like those in the original (primary) tumor.

Detailed explanation-4: -Cancer spreads-or metastasizes-when cancer cells break away from the original tumor and travel through your bloodstream or lymphatic system to other parts of your body.

Detailed explanation-5: -Lymphatic Metastasis Cancer can use the lymphatic system as well as the circulatory system to metastasize. The movement of cancer cells via the lymphatic system into lymph nodes is used in the detection of metastatic disease and tumor staging.
