Income disparities in loss in life expectancy after colon and rectal cancers: a Swedish register-based study.

Background: Differences in the prognosis after colorectal cancer (CRC) by socioeconomic position (SEP) have been reported previously; however, most studies focused on survival differences at a particular time since diagnosis. We quantified the lifetime impact of CRC and its variation by SEP, using individualised income to conceptualise SEP.

Methods: Data included all adults with a first-time diagnosis of colon or rectal cancers in Sweden between 2008 and 2021.
