Approximately 2 months ago I had a core biopsy on my lower leg. Consultant thought it was basal cell carcinoma or Bowens Disease. I have heard nothing until today when I received a letter saying an appointment had been made for me to attend the Cardiovascular Ultrasound Unit for US Ankle / Brachial Pressure Index. I'm not sure why? I vaguely remember consultant saying if I needed another operation with a skin graft they would have to test out my arteries first or something similar. I'm really worried this is something sinister that I haven't been told about. Many thanks in advance.
