Only joking: still no evidence of any harmful effects. The study looked at 400,000 people, many of whom have been using mobiles since 1984, and it included both analogue and digital handsets. As The Register notes:
the study found that long-term mobile phone users had a slightly lower incidence of cancer than the general population, though this can be attributed to being from the upper-income demographic, still one of the most important factors in illness and life expectancy.
The report’s conclusion:
We found no evidence for an association between tumor risk and cellular telephone use among either short-term or long-term users. Moreover, the narrow confidence intervals provide evidence that any large association of risk of cancer and cellular telephone use can be excluded.
