Can you tell me what this is? I was told it may be basil cell cancer but it is sore and infected. (photo)

I have had it for 2 months. Started as a boil I though but grew. It is sore and infected. I clean it with alchohol. I have no insurance to see a doctor and need it treated or removed. 47 years old phoenix arizona I had a basil cell on my shoulder removed in 2014 but this looks nothing like it.
