Definition: After a remission of cancer, if signs or symptoms of cancer reappear, that is called a "recurrence," where cancer cells can reappear in the site of the primary tumor or can show up in a new location.
Also Known As: relapse, return, reappearance
Examples:
Most breast cancer recurrence happens in the first three to five years after initial treatment. The recurrence can be local (in the same breast or in the surgical scar) or it can be a distant recurrence (lymph nodes, bones, liver or lungs).
