Holly, I can’t comment on bone mets specifically to the foot but my wife had radiation to mets in pelvic bone, right and left femurs with very good results. She had minimal side affects (only minor rash at radiation site). Pain relief started quickly around half way thru the 10 treatments for each met and she continues to be pain free from those mets today. I know not everyone responds the same to radiation, but for her it has been the easiest treatment regimen she has had while fighting melanoma. Good luck. George
