how can cancer spread from one part of the body to another
Through the lymphatic system, cancer can spread to other parts of the body. Lymphoma: A cancer of the lymphatic system. Lymphoma begins when cells in the lymph system change and grow uncontrollably. Sometimes a tumor is formed. Malignant: Refers to a tumor that is cancerous. It may invade nearby healthy tissue or spread to other parts of the body. Mass: A lump in the body. Metastasis: The spread of cancer from the place where the cancer began to another part of the body. Cancer cells can break away from the primary tumor and travel through the blood or the lymphatic system to the lymph nodes, brain, lungs, bones, liver, or other organs.
