Would a itchy lump on the armpit be a sign of cancer?

Sorry to jump in but.. One of my friends think she has breast cancer. And here's why.
She told me, plus another friend of ours, that she had a painful, irritated, and yet incredibly itchy, lump on her armpit, and she also told us that her breasts were.. hurting? Would that be a sign of Breast Cancer? She also told me that she feels cold and dizzy, and that her body hurts too.

    I'm not a medical professional but just wanted to say it's always always always worth getting these things checked. Your mate should book an appointment with her gp soon. It's all a very simple process and chances are it's fine but it's so difficult to tell without the proper tests. 

    I've had lumps before that were benign. But my breast cancer lump was painful and itchy! Is there a particular reason your friend hasn't been to the doctor's?
