Cellphone Causes Cancer..True?

I was really curious when i hear lots of people saying that cellphones can cause cancer..so i decided to do some research on the internet on whether cellphones cause cancer..this is the article i found..

-3-case control studies-
First, the patients with brain cancer did not report more cellular phone use overall than the controls. This finding was true when all brain cancers were considered as a group, when individual types of brain cancer were considered, and when specific locations within the brain were considered. In fact, most of the studies showed a tendency toward a lower risk of brain cancer among cellular phone uses, for unclear reasons.
Second, none of the studies showed a "dose-response relationship" -- a tendency for the risk of brain cancer to increase with increasing cellular phone use, which would be expected if cellular phone use caused brain cancer.
Third, the studies did not show a clear link between the side of the head on which the brain cancer occurred and the side on which the cellular phone was used (with the possible exception of the Swedish study).
Results of the long-term cohort study, which linked data on all of the 420,095 cellular telephone users in Denmark between 1982 and 1995 to the Danish Cancer Registry, agree with the findings of the case-control studies. Cellular phone use, even for more than 10 years, was not associated with an increased risk of developing brain tumors or cancer overall, nor was there an association with any brain tumor subtypes or with tumors in any location within the brain. As in the case-control studies, no link was found between brain tumor risk and RF dose, as assessed by length of cellular phone use, date since first subscription, age at first subscription, or type of cellular phone used.

In summary, there is now considerable epidemiologic evidence that shows no consistent association between cellular phone use and overall risk of brain cancer. Some uncertainty remains regarding a possible association with acoustic neuromas. Several large studies now in progress will add markedly to the evidence within a few years.

I read a number of articles and a few articles states that it is inconclusive..so it's up to you to believe whichever article you want about whether cellphones really do cause cancer or not..thanks

I just took out some important points..you can read the entire article here..
