Could this growth be sarcoma?
I just noticed this strange protrusion today since it's on the back of my arm. It's kind of flat and barely noticeable even when running my fingers over to feel it. It's very squishy, only slightly tougher than the surrounding skin and doesn't feel like a ball in my flesh. It just feels like my skin but swelled. No pain. Is this what a sarcoma looks like? Is it a flat sarcoma? I'm very scared and of course I'll be going to my doctor as soon as possible but I need peace of mind right now. What's the typical appearance of a sarcoma on the extremities?
