The risk of cancer decreased with a start as a male seafarer after 1985, with a significant trend for total cancer ( P < 0.001), lung cancer ( P = 0.001) and, for tanker seafarers, leukaemia ( P = 0.045).
The risk of cancer decreased with a start as a male seafarer after 1985, with a significant trend for total cancer ( P < 0.001), lung cancer ( P = 0.001) and, for tanker seafarers, leukaemia ( P = 0.045).
Increased cancer risks were primarily associated with an early start in seafaring (< 1985) and there was a decreasing trend in cancer with later first employments.
