Generally, the recurrence rate of cancer is higher in the first to second year of a five-year period, but the time of recurrence varies among different patients and they should be rechecked on time. Different cancers have different recurrence rates, for example, lung cancer, breast cancer and cervical cancer have higher recurrence rates. In addition, the recurrence rate of different patients is also different. If the life is irregular and the diet is not controlled after the standard treatment, the possibility of recurrence is also higher than other patients, therefore, there is no specific recurrence time. However, in general, most of the patients with recurrence have recurrence within 1~2 years after treatment. It may be due to the fact that some tiny lesions are not removed cleanly, which leads to the recurrence of the disease. Therefore, in the clinic often 1~2 years after the treatment of the review is more frequent, may be every 3 months to review, 2 years after the review can be 6 months, the purpose is to timely detection of problems. It is recommended that patients follow the doctor’s advice time on time for review, usually pay attention to changes in lifestyle, do not stay up late, do not eat spicy and stimulating food, try to improve the prognosis and reduce recurrence.
