"...risk may be as great as a two- to four-fold increase of developing a tumour on the same side of the head..."

This phrase is a bit of a giveaway; it makes me think that this is the same study as another that used very similar language a while ago. The key difference is that this seems to be FUDing whereas the other concluded that more study needs to be done to find the cause of the correlation, eg it might be to do with 'handed-ness'.
