Cervical cancer mortality is increasing in Spanish women younger than 50.

Spanish women seem to have low cervical cancer mortality rates and some studies suggest the trend is stationary; however, this fact remains unclear because a great number of uterine cancer cases are classified as site unspecified. The main goal in this paper is to study mortality trends due to cancer of the cervix in young Spanish women. The percentage of uterus cancer deaths recorded as site unspecified has fallen from 90% in 1965 to 25% in 1995. Mortality by cervical cancer decreases in women aged 25-49 born before 1939-1948 and increases in women born later. This result is shown in each 5-year age group and seems independent from the percentage of unspecified site uterine cancer. In conclusion, Spanish women aged under 50 are suffering an increase in cervix uteri mortality rates; this rise can be related with behavioural changes occurring from 1970-1975 on.
