Is this cancerous?

Lindsey

I had this same thing on my hand on my arm a few months back. It started out as itching with no patch, then it shows up to be a circle patch like this one. It’s bumpy, seeps.. and is super dry if I don’t keep moisture on it. The itch is like a poison ivy itch. Super uncomfortable and is sore/painful at times. Is this a sign of cancer?
