With the change in the life styles and demographic profiles of developing countries, noncommunicable diseases are emerging to be important health problems that demand appropriate control program before they assume epidemic proportion. One of these is the problem of cancer. In India, cervical cancer is a significant problem in terms of incidence, mortality and morbidity. Cervical cancer is a disease that can be prevented through both primary prevention and early detection using screening techniques. Several screening modalities are now available for early detection of cervical cancer and its precursor lesions. They all differ with regard to their test characteristics, feasibility and economic considerations. This communication reviews different aspects of these screening modalities and provides different options considering mass application.

Carcinoma of the cervix is one of the leading malignancies in the developing countries including India. In view of this health care program might have to be redefined. Most of the data are available from the developed countries, which rely mainly on cytology screening on regular basis. This however may not be feasible in developing countries because of various constraints. Thus alternative approaches are needed based on risk reduction modalities. This article while dealing with the control approaches based on secondary prevention, reviews several risk factors associated with cervical cancer. The various articles were approached through Medline search including cross-references. The important life styles associated with cervical cancer and which are amenable to primary prevention strategies through health education, behavioral interventions, legislative approaches and modifying the health care seeking behavior were identified through the review process. These factors mainly pertain to early sexual debut, multiple sexual partners, menstrual hygiene and unprotected sex. Role of male partners has also been delineated in the process of cervical carcinogenesis. These factors are essentially conducive to the transmission of an etiological agent; the high-risk types human papillomaviruses, the more proximal cause in the web of causation. Barrier method of contraception and prophylactic vaccine in future could help to check the transmission of the virus. Role of smoking and oral contraceptives has also been discussed. Till the facilities for mass scale screening are developed in developing countries the primary prevention approaches could certainly help to check the incidence of the disease.

This is an attempt to understand the magnitude of cancer problem in India. The incidence data generated by the three population based cancer registries at Bangalore, Bombay and Madras and the population projections of country have been utilised for estimating the present and future load of new cancer cases. It is estimated that the total number of incident cases in males increased from 0.29 million to 0.43 million by the turn of the century as a result of change in size and composition of population and when adjusted for tobacco habits the estimates increased to 0.49 million. In females the incident cases of cancer for three registries increased from 0.32 to 0.42 million by 2001, with cancer of uterine cervix and breast being the major problems. The above results show an urgent need for strengthening and augmenting the existing diagnostic/treatment facilities which are vow fully inadequate to tackle even the present load.
