diagnosis

3 yrs ago I had a rapidly enlarging growth removed from my left thigh it was around 11 centimeters at the time of removal . The ortho guy assured me it was beniegn even though he said he never saw anything like this before . I even saw the Top guy who deals with sarcoma like things and he said it couldn't possibly be sarcoma because these things don't grow that quickly ...NO BIOPSY . Now the tumour has grown back in the same spot bigger deeper and when I try to walk my leg turns purple  Getting to see a sarcoma specialist has been a challange because I live in Canada where we have free health care and just because its free doesn't mean it 's good.  finally have an appt next week after 5 months of this even the cancer center in our area said it has to be seen by Sarcoma Center. Has anyone been throgh this before?
