I had a 1.9 cm ups removed in October and going thru 35 radiation treatments now. I think we caught mine early and I was told it was superficial. It was on my left shoulder and the 1st CT scan said no other problems. Mid March is my next check up and I am doing well. I have continued everything I was doing other than being able to head to a warmer climate. Seems no one knows much about ups. Good luck 🤞
