Full-term pregnancies and incidence of ovarian cancer of stromal and germ cell origin: a Norwegian prospective study

Br J Cancer. 1997;75(5):767-70. doi: 10.1038/bjc.1997.136.


Associations between the incidence of stromal and germ cell ovarian cancer and pregnancies were examined in a follow-up of 1.1 million women aged 20-56 years. Stromal tumours (41 cases) showed no clear associations. Germ cell tumours (71 cases) were related to high-age childbirths and short time since birth.
