Reproductive factors and prognosis of uterine cervical cancer in Norway.
Based on Norwegian registry and census data, the influence of reproductive factors on excess mortality from cervical cancer was examined. Parity level had no impact on the excess mortality. In parous women, a beneficial effect of an early first birth was found, most pronounced in 20- to 39-year-old women with squamous cell carcinoma.
