Hi, I have to have 10 fractions of targeted radiotherapy for a  metastasised tumour in my thigh muscle.  Apparently this tumour is uncommon as my primary tumour is in my lung which had already metastasised to my liver and brain.   So I understand the radiotherapy is only palliative.  What I dont know is what the side effects of the radiotherapy may be - the immediate ones and longer term.  I would like to be as prepared as I can be, can you advise?   I am not worried about the treatment itself.  Many thanks
