Metastasis


Definition:

Metastasis is the movement or spreading of cancer cells from one organ or tissue to another. Cancer cells usually spread through the blood or the lymph system.

If a cancer spreads, it is said to have "metastasized."

Alternative Names:

Metastatic cancer; Cancer metastases

Information:

Whether or not cancer cells spread to other parts of the body depends on many things, 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 spread.
