Figures: NCI SEER and the American Cancer Society. Lifetime risk is SEER's 13.0%, from 2021–2023 data; SEER counts in situ disease separately, which is why this figure is invasive cancer. The survival figure is for cases diagnosed 2015–2021, and ACS notes the localized group "only includes invasive cancer. It does not include ductal carcinoma in situ." "Relative survival" compares people with the diagnosis to the general population; individual outcomes vary.
