^aLimited to diagnoses for workers with no time in an unknown job category.

^bAggressive is defined as distant stage at diagnosis or underlying cause of death due to same cause as cancer diagnosis.

^cSignificance test for median based on Wilcoxon two-sample test.

^dCumulative exposure (in unit-years) is product of the number of days in each department and job-title and the assigned score, summed over all jobs worked, and divided by 365.25.
