I was very interested to read Graham Parfitt's comments about mobile phones (Letters, November 23).

I recently spent some time in the Royal Sussex County Hospital and, during my stay, I was told by a doctor how dangerous these phones could be to health.

I also met a doctor on my return home who told me about the increase in brain cancer due, he thought, to the constant use of mobile phones.

I have a son now dying of brain cancer. Thanks to his high profile in business he seemed never to be off his mobile - and though he retired this year, it was all too late.

I hope a warning from the medical world will very soon come out - the young today seem to be glued to their mobiles.
