If some studies fail to show a link between mobile phone use and cancer, doesn’t that mean the technology is safe?
A study with negative results (no association) does not balance out one with positive results (showing an association). We don’t have to be sure that the technology ALWAYS causes damage; we need to be concerned if it SOMETIMES causes damage. It may cause damage only after sufficient exposure, or after a latency period; it may cause damage to some people and not others. It is only by looking at all the studies together that we can form a picture of whether health concerns have some justification. It is no consolation to a parent that their child may not be affected, if there is a chance that their child will be affected. There is every prospect that the studies that fail to show a link may simply be studying the particular people who are not affected, or the people who are not affected YET. Many of the negative studies didn’t include long-term users so the people studied might have gone on to develop cancers. We will have a clearer picture as more studies are carried out but, in the mea
