SIRs were high among chimney sweeps (6.71,<br />
1.38 19.61, based on only 3 cases), <strong>and</strong> tobacco<br />
manufacture workers (Table 23). A low SIR was<br />
observed among the female beverage manufacture<br />
workers (0.59, 0.36 0.92).<br />
Comment. The variation in rectal <strong>cancer</strong> risk between<br />
occupational categories is very small. Workers in<br />
tobacco manufacturing may smoke more than the<br />
general population, <strong>and</strong> hence the increased risk<br />
among females working in tobacco manufacturing<br />
may be explained by smoking, which is an established<br />
risk factor of rectal <strong>cancer</strong> [65]. The increased<br />
risk among male <strong>and</strong> decreased risk among female<br />
beverage workers may well be an example of a<br />
situation where the men <strong>and</strong> women under the<br />
same occupational code do different types of work.<br />
Men may work mainly with beer brewing, while<br />
women with other types of beverages. Earlier studies<br />

suggest that alcohol consumption which may be<br />
high among brewery workers may increase the<br />
risk of rectal <strong>cancer</strong>. Lack of physical activity or<br />
sedentary work has not been clearly associated with<br />
the risk of rectal <strong>cancer</strong> [66].<br />
Liver <strong>cancer</strong><br />
Liver <strong>cancer</strong> is rare in the Nordic countries. The<br />
pattern is very similar in the two genders, although<br />
with a lower rate among women (Figure 22).<br />
Among men, waiters (SIR 4.22, 95% CI 3.47<br />
5.13), cooks, beverage workers, journalists <strong>and</strong> seamen<br />
ranked as the five groups with the highest risk.<br />
At the other end of the scale were farmers (0.47,<br />
0.45 0.50), gardeners, forestry workers, teachers,<br />
fishermen <strong>and</strong> wood workers (Table 24).<br />
In women, the risk of primary liver <strong>cancer</strong> did<br />
not vary much across the different occupations<br />
(Table 25). Significantly elevated risks were seen<br />
