They found no statistically significant effects of mobile phone use on cancer rates, just like very other study that has been done. Those studies which found a correlation between phone use and cancer were conducted on very small groups, so have no statistical significance - if you talk to one person, who then happens to get cancer, that does not mean that 100% of people get cancer, it means your sample size is too small.
Having found no statistical effect, they now want more money to further study... what... the noise? The variation in the amounts of exactly how much nothing is going on? Surely it is now time to put this one to bed and start spending the money on something more worthwhile, like, ooh, I don't know, actual funding of cancer research. Although certain cancer types, such as breast cancer, get plenty of funding due to high-profile campaigning, there are plenty of cancer types that do not get enough funding (such as prostate). It is also worth remembering that cancer is not a single diease, but many many different diseases that manifest themselves in a similiar fashion.
Failing that, rather than pissing money up the wall, they can give it to me, and I can conduct a study into the effects of beer on my sobriety. Since there would be a small number of participants in this experiment (one), it would be necessary to repat the experiment several times in order to be assured of a valid result.
