Detailed explanation-1: -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-2: -In metastasis, cancer cells break away from where they first formed and form new tumors in other parts of the body.
Detailed explanation-3: -Most cancer cells that break free from the primary tumor are carried in the blood or lymph system until they get trapped in the next “downstream” organ or set of lymph nodes.
Detailed explanation-4: -Intravasation is the entry of tumor cells into the blood-stream. Newly formed tumor vessels are often defective, a property that may facilitate the entry of tumor cells into the circulation [9, 10]. At the invasion front, tumor cells also may invade preestablished host vessels [1].
