Lump in breast, no health insurance.

For the past year, I've been feeling a hard little lump in a very specific spot on my right breast. I've repeatedly felt soreness in that particular area, as well. I'm 25 years old, live on my own and have no health insurance. I've only ever worked for minimum wage and can't afford to pay out of pocket. I have no children.

What can I do? I don't really have anyone in my life I can turn to for something like this. Advice would be much appreciated, thank you in advance.
