It could also be argued that, because the acoustic neurons on that side of the head are being used more, they're more likely to be cancerous, or that both are caused by a similar issue.
That sounds pretty convoluted to me. It could be true, but it probably isn't. If, as the paper abstract seems to indicate, long-term (but not short-term) cellphone users are getting fourfold more acoustic neuroma on the side of the head they use their cellphone on, as compared with the other side of their head, I'd say that the most likely explanation is that cellphone use is responsible.
