But our dramatic progress in detecting and treating cancer has also led to growing awareness of the problem of tumor dormancy: a patient appears to be cured, only to have the same cancer return years or even decades later. In breast cancer or melanoma, for example, recurrences 25 years after initial treatment have been reported.
但我们在检测和治疗癌症方面所取得的重大进展也引起了对肿瘤休眠问题的更多重视：病人往往似乎被治愈了，但却在数年甚至数十年之后复发。比如在乳腺癌和黑素瘤方面就有25年后再度复发的报告。
