[Role of nanomaterials in the diagnosis of prostate cancer: An update].

Prostate cancer (PCa) is one of the most common malignant tumors of the genitourinary system in middle-aged and elderly men. The incidence of PCa has been increasing year by year in China in recent years, posing a major threat to the physical and mental health of Chinese men. With the rapid development of nanotechnology, the research of nanomaterials in biomedicine is increasing, which effectively promotes the application of nanomaterials in the early diagnosis of a variety of tumors, including PCa. This article reviews the latest research progress of nanomaterials in the diagnosis of PCa.
