Objective To analyze the incidence and epidemic characteristics of malignant tumors in urban residents in Jiangmen City and provide evidence for the development of prevention and treatment measures of malignant tumors. Methods Descriptive epidemiological analysis of the incidence of malignant tumors in urban residents in Jiangmen City from 2011 to 2014 was conducted. Results The average annual incidence of malignant tumors in urban areas was 285.82 / 100,000 in 2011-2014.

The incidence of males was 308.58 / 100 000, the incidence of females was 263.27 / 100 000, the sex ratio of males and females was 1.16:1. There was significant difference in the incidence of malignant tumors among different sex groups (P <0.01). There was no significant difference in the incidence of malignant tumors between men and women in different years (all P> 0.05). The number of patients aged 45 and over accounted for 83.71% (6 142/7 337) of the total number of cases. The top 5 malignant tumors were lung cancer, colorectal cancer, liver cancer, breast cancer and nasopharyngeal cancer, accounting for 56.51% of the total number of malignant tumors.
