My son has cancer in his head (not brain but soft tissue) - he has given me no details

Hi SwimWalker. Welcome to our community. So sorry to hear such bad news. There are a couple of people here who have had proton as a first line treatment 

All I know is that Proton beam is still radiotherapy but it can be more finely tuned to avoid normal tissue. So in that respect it can be used in a palliative setting. after ordinary xray radiotherapy has been used. 
Will it be to ease symptoms? 
I hope the Marsden can do something for him. 
Best wishes 

1. I got the relayed info totally wrong. He's actually going to a clinic in Reading tomorrow - I haven't spoken to him face to face recently as he gets tired very easily, it's a Whatsapp life. He seems to be thinking that it's a new type of treatment. Anyway I expect I'll get an update in a few days. 

No worries. Let us know how he gets on. Fingers crossed
