were significantly below 1.0 among female sales<br />

agents (0.69, 0.46 0.98) <strong>and</strong> among ‘‘other workers’’,<br />

i.e., economically active women not classified in<br />

any of the 52 specific occupational categories if the<br />

Comment. Non-melanoma skin <strong>cancer</strong> <strong>and</strong> skin<br />

melanoma (Tables 54, 55) have quite similar SIRs.<br />

Several chemical compounds have been identified as<br />

associated with an increased risk of skin <strong>cancer</strong>.<br />

These include arsenic <strong>and</strong> arsenic compounds, <strong>and</strong><br />

components of oil, tar, <strong>and</strong> combustion products<br />

such as PAHs. Cumulative solar exposure is also<br />

considered a skin carcinogen, which in the context of<br />

outdoor occupations is related to work [130]. In our<br />

study, however, we did not identify patterns of SIRs<br />

that could be related to either occupational solar<br />

exposure or chemical exposures. The highest SIR<br />

was obsersved among physicians, identically in both<br />

genders, which might indicate that there is some<br />

diagnostic bias which overrules the possible weaker<br />

effects of occupational carcinogens.<br />

Skin <strong>cancer</strong> in the upper limbs was studied<br />

separately to reveal the possible effects of dermal<br />

exposure at work. One might speculate that the<br />

excess risk in health care personnel, seamen or<br />

military personnel might be related, e.g., to products<br />

they h<strong>and</strong>le in their work, including disinfection<br />

liquids.<br />

Eye <strong>cancer</strong><br />

The incidence of <strong>cancer</strong> of the eye has remained fairly<br />

stable around 1 per 100 000 in men, <strong>and</strong> a bit lower in<br />

women in all Nordic countries (Figure 40).<br />

Only a modest risk variation across occupational<br />

categories was found (Table 58). For men, the only<br />

significantly elevated SIR (1.35, 95% CI 1.09 1.66)<br />

was found for transport workers, <strong>and</strong> the only<br />

significantly low SIR (0.81, 0.70 0.95) was found<br />

for economically inactive men. No occupational<br />
