It seems like the soreness dissipates once my period starts but I cannot tell for sure if the swelling completely goes away. Relative to my armpit on the right side, it seems like there is a mass or growth on the left. I have a doc appt. scheduled for this week but I thought I would check to see if anyone has experienced this. Cancer runs in my family so I am a bit worried. Any advice or relevant comments would be appreciated. amsp00 Mon, 25 Feb 2008 00:00:00 GMT You are doing the right thing and having it checked out.  Any time there is an unknown cause for a lump or swelling it should be investigated ASAP.   Good luck to you!
