It was interesting that leukaemia clusters around a nuclear plant in the UK were first blamed on radiation, but it was later discovered that they were due to infections introduced into the local population by migrant labourers building the plant. Can anyone get these infections, or do you need a genetic defect as well in order for cancer to result? Removing STDs from the list of carcinogenic infections are the figures much reduced? Another thought that has often interested me is the possibility that an infection you are given as a child and which apparently self limits is the cause of a cancer you develop when you are an old person. Is there any reality in such an idea?
