Objective To understand the current prevalence of cervical and breast cancers and their influencing factors in women aged 30-64 years in Xiangyang city.
Methods A questionnaire survey was conducted to collect information of demographic characteristics, past medical history, family tumor history, menstrual and reproductive history and the prevalence of common gynecological diseases among married women aged 30-64 years in Xiangyang. Cervical cancer screening was performed primarily by high-risk HPV typing detection, followed by Thinprep cytologic test, colposcopy and pathological examination. Breast cancer screening was performed through visual inspection, palpation and color Doppler ultrasonography, followed by X-ray mammography and pathological examination.
Results A total of 318067 women participated in the screening in 2017, among which 91143(28.66%) cases had non-HPV genital tract infection and 91143(28.66%) cases had benign uterine disease; 826(259.69/105) cases had cervical precancerous lesions, including 385 cases of CINⅡ, 425 cases of CINⅢ and 16 cases of adenocarcinoma in situ; 79(24.84/105) cases were cervical cancer, including 18 cases of microinvasive carcinoma and 61 cases of invasive cancer; 44097(13.86%) cases had benign breast disease and 80(25.27/105) cases were breast cancer. Multivariate regression analysis indicated that age, family history of cervical cancer, multiple pregnancies, delayed menopause and reproductive tract infection may be risk factors for cervical cancer, while age, high level of education and family history may be risk factors for breast cancer.
Conclusion The incidence of cervical and breast cancers in Xiangyang city is at a moderate level. Regular screening and active control of high-risk factors are of great significance to the prevention and treatment of cervical and breast cancers.
