Disease relapse is the reappearance of disease symptoms after a period of remission. Recurrence can occur in various diseases including cancer, mental illnesses and autoimmune disorders. Recurrence may occur due to incomplete treatment, resistance to treatment, or genetic predisposition.

In some cases, lifestyle factors such as Diet and exercise can affect the likelihood of relapse. Early diagnosis and prompt treatment are very important to manage recurrent disease and prevent complications. Patients with a history of relapse may require ongoing care and monitoring to ensure that new symptoms resolve quickly.
