Metastasis

Lymph node metastases, CT scan

A CT scan of the middle abdomen showing a large tumor mass due to metastasis (spreading cancer) in abdominal lymph nodes.

Also known as: Metastatic cancer and Cancer metastases

Definition

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.

Information

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.
