I Found A Hard Lump On My Chest And I Think I May Have Cancer

Hello everyone first I would like to say that I take full responsibilty for the positon I am in and now understand repurcussions of my bad life decisions.  I was a smoker for 24 years now and I just recently quit.  And, a few days ago I found a hard lump on my chest and I researched online what it may be and everything points to cancer.  I recently was let go from my job and had to move out of state to stay with a friend until I could find work. I have no medical insurance or income; and even to go to urgent care would cost around $400.00.  I have no money and would really like to go and have this checked out and a little help with my current living expspenses would be appreciated as well.
