As two different types of diseases,Parkinson’s disease is a common degenerative disease of the nervous system,while the tumor is a malignant proliferative disease. Epidemiological studies suggest that the incidence of Parkinson’s disease is related to the incidence of cancer,but the common pathogenesis of the two has not been completely clear until now. The research on the pathogene-sis of these diseases will help provide a basis for screening and early diagnosis of two diseases,and provide clues for searching for more effective intervention measures.
