Metastasis is the movement or spreading of cancer cells from one organ or tissue to another. Cancer cells usually spread through the bloodstream or the lymph system.
Metastatic cancer; Cancer metastases
Whether or not cancer cells metastasize (spread to) to other parts of the body depends on many factors, including:
- The type of cancer
- The stage of the cancer
- Original location of the cancer
Treatment depends on the type of cancer and where it has metastasized.
