Armpit and Breast

Hi everyone

for a while, I've had a tiny red mark and tiny bruise on my breast. Recently I've started with pain deep in my armpit. 
 

todya I went to the doctors and she examined my breast and found a small lump so has referred me. Now I'm completely terrified.

 

anyone else had this? Outcome? Treatment? Or at I been paranoid
