Gentlemen. My son is a serving Royal Marine (17 years) He has just been casevaced from Norway having suffered a siezure and subsequentlly diagnosed with a brain tumour. He is to have surgery in 2 weeks time. He is a signaller and has used Bowman Radios a great deal earlier in his career. I have become aware of a rumoured link between Bowman and brain tumours. If anyone on this site has any knowledge, good or bad, that can be shared with me I will be most grateful.
