Epidemiology of cancer of the cervix: global and national perspective

J Indian Med Assoc. 2000 Feb;98(2):49-52.

Abstract

Cancer of the uterine cervix is one of the leading causes of cancer death among women worldwide. The estimated new cancer cervix cases per year is 500,000 of which 79% occur in the developing countries. Cancer cervix occupies either the top rank or second among cancers in women in the developing countries, whereas in the affluent countries cancer cervix does not even find a place in the top 5 leading cancers in women. The truncated rate (TR) in the age group 35-64 years in Chennai, India, is even higher (99.1/100,000; 1982-95) than rate reported from Cali, Colombia (77.4/100,000, 1987-91). The cervical cancer burden in India alone is estimated as 100,000 in 2001 AD. The differential pattern of cervical cancer and the wide variation in incidence are possibly related to environmental differences. Aetiologic association and possible risk factors for cervical carcinoma have been extensively studied. The factors are: Sexual and reproductive factors, socio-economic factors (education and income), viruses e.g., herpes simplex virus (HSV), human papillomavirus (HPV), human immunodeficiency virus (HIV) in cervical carcinogenesis and other factors like smoking, diet, oral contraceptives, hormones, etc. The accumulated evidence suggests that cervical cancer is preventable and is highly suitable for primary prevention. Sexual hygiene, use of barrier contraceptives and ritual circumcision can undoubtedly reduce cervical cancer incidence. Education, cervical cancer screening of high risk groups and improvement in socio-economic status can reduce cervical cancer morbidity and mortality significantly.

PIP: Cancer of the uterine cervix is one of the leading causes of cancer death among women worldwide. The estimated number of new cervical cancer cases per year is 500,000, of which 79% occur in developing countries. Cervical cancer is ranked highest or second-highest among cancers in women in developing countries, whereas in affluent countries cervical cancer does not even rate within the top 5 leading cancers in women. The truncated rate in the age group 35-64 years in Chennai, India, is even higher (99.1/100,000; 1982-95) than the rate reported from Cali, Colombia (77.4/100,000; 1987-91). The cervical cancer burden in India alone is estimated to reach 100,000 by 2001. The differential patterns of cervical cancer and the wide variation in incidence are possibly related to environmental differences. Etiologic associations and possible risk factors for cervical carcinoma have been extensively studied. The factors are: sexual and reproductive factors; socioeconomic factors (education and income); viruses (e.g., herpes simplex virus, human papillomavirus, HIV); and other factors such as smoking, diet, oral contraceptives, hormones, etc. The accumulated evidence suggests that cervical cancer is preventable and is highly suitable for primary prevention. Sexual hygiene, use of barrier contraceptives, and ritual circumcision can undoubtedly reduce cervical cancer incidence. Education, cervical cancer screening of high-risk groups, and improvement in socioeconomic status can reduce cervical cancer morbidity and mortality significantly.
