Cancer usually recurs within a few years.

The longer the survival time, the lower the probability of tumor recurrence. According to incomplete statistics, if the patient's tumor has not shown recurrence and metastasis for more than five years, the patient's tumor can be considered cured. For most tumor survivors, if the tumor has not recurred and metastasized for more than five years, the probability of future recurrence may only be between 5 and 10%.
