A sub-site-specific analysis of the relationship between colorectal cancer and parity in complete male and female Norwegian birth cohorts.
Register and census data for complete cohorts of Norwegian men and women born between 1935 and 1969 have been used to examine the relationship between reproductive factors and the incidence of colorectal cancer.
Among 1.1 million men and 1.1 million women under observation, 491 male and 859 female cases of colorectal cancer were diagnosed during the period of follow-up.
Our hazard model estimates clearly show that in these young cohorts, women with 2 or more children run a lower risk of having a malignant tumor in the cecum or ascending colon than do other women of the same age and in the same birth cohort.
