Cancer on right kidney?

my daughter had a kidney problem when she was little. apparently it was a birth defect that went unnoticed. then when she was 17 ( she's almost 19 now) she had it removed because it died and became infected and cause great pain. perhaps if the cysts popped it could cause an infection through the blood stream. having a kidney removed isn't as much as someone donating a kidney. get a second opinion. either way it sounds like there will continue to be pain. good luck
