I went to the Dr as I thought I had a new mole. He referred me to the hospital. My appointment is on 4 June. My arm aches sometimes. I looked through old photos and I had this "mole" in October. It concerns me this has got worse and won't be at stage 1 as I thought that would be where I was as I thought I had only had this about 8 weeks. How long does it take to go from stage 1 to stage 2.my appointment is next week.
