A cohort of 127,547 US postmenopausal women was analyzed over three decades for ovarian cancer incidence by estimated residential radon zone. Women in zones above 4 picocuries per liter had a 31 percent higher adjusted risk of ovarian cancer than those in zones below 2 picocuries per liter. Mortality from ovarian cancer was also significantly elevated, with the strongest signal for serous ovarian cancer, the most lethal subtype.
