We calculated age standardized rates (ASR) using the direct method adjusted to the World Standard Population. Years of life lost (YLL) due to those cancers were calculated using Japanese life tables. Average lifespan shortened (ALSS) measure was calculated as a ratio of YLL to the expected lifespan. We used the bootstrap method to calculate the 95% confidence interval (95% CI) for the ALSS measure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The ASR for death remained mostly stable over the study at about two deaths per 100\u2009000 women for cervical cancer, and three deaths for ovarian cancer. The ALSS values report that women who died from cervical cancer lost on average 28.3% of their lifespan (95% CI: 27.7\u201328.9) in 2000 and 26.6% (26.1\u201327.2) in 2020. Women who died from ovarian cancer lost on average 26.9% (26.5\u201327.4) and 23.5% (23.1\u201323.9) of their lifespan in 2000 and 2020,
