i had an excision of a melanoma that ,mix weeks later, I was told was stage 1a, but now a wider excision will happen this week. I am very worried they have wasted time and that it has regrown since the first excision because they took so long. My fear is that the second excision will have seedlings of cancer in it. Anyone else had such an experience? Will,the histology delay mean the next chunk,they take out may well be cancerous? What are the chances of this.?
