Hi, I have a small movable lump near my right armpit and a dull pain on right side of my breast, under armpit and all down my right breast. I noticed it about 4 weeks and it hasn't gone away. Am getting quite worried now and thinking about making an appointment with my doctor this week. Was wondering if you had any ideas on what could could be the cause of this? I'm imagining the worst!
Kind Regards Davina
