Secondary cancers (metastases)

When a cancer starts in one place in the body and spreads elsewhere, this is a secondary cancer or a ‘metastasis’.

The place in the body where a cancer first starts is the ‘primary cancer’. Sometimes, cancer cells can break off from the primary cancer and spread elsewhere in the body. Cancer can then grow in another part of the body.

When this happens, this is secondary (metastatic) cancer.
