[Mortality from uterine cervix cancer in Rio Grande do Sul]

The mortality from cervical cancer was studied by checking the death rates in Rio Grande do Sul (RS) and in its 24 microregions. Each tendency (linear regression), in the period from 1970 to 1989, was also investigated. We have also studied the relative rates of this kind of cancer, the comparison with the rate in other places and the risk factors. The data were obtained at the Office of Health in Rio Grande do Sul as well as in the Statistics and Geography Brazilian Institute and World Health Organization. The average mortality rates/100,000 women in RS (1970-1989) was 3.8, with ascending tendency. Important differences in the death rates in the 24 microregions in RS were observed and they ranged from 2.5 to 6.7. The cervical cancer was the fourth cause of death in women from RS (mortality by cancer), in 1989. Papillomaviruses and smoking were important factors in the development of cervical cancer.
