, oh, no. I am so sorry you are dealing with skin cancer on top of MS. I hope you are able to get to that dermatologist soon and get treatment going. If you are interested, we do have a sister site dedicated to skin cancer, which you are welcome to check out -- https://skincancer.net/. Again, I hope you are able to get treatment going and that it's not too invasive or disruptive to your life AND (most importantly) that you are able to get rid of the cancer.
