Repeated exposure to dental X-rays ups thyroid cancer risk
London: Repeated exposure to dental X-rays increases thyroid cancer risk, a new study has revealed.
Analysing 313 cancer patients, scientists from Brighton, Cambridge and Kuwait found the chances of developing cancer rose with increasing numbers of dental X-rays.
"The public health and clinical implications of these findings are particularly relevant in the light of increases in the incidence of thyroid cancer in many countries over the past 30 years," the Telegraph quoted Dr Anjum Memon, of the Brighton and Sussex Medical School, as saying.
However, Dr Memon was quick to add that the increasing use of sensitive diagnostic techniques does not necessarily account for the entire increase and that other causes warrant investigation.
