Dear levaeh: Without evaluation, it is impossible to speculate on what this might be. The general rule of thumb is that a new lump should be evaluated. There are many possible explanations for lumps. Most breast cancer is not painful.
oops, sorry...i thought i was in the support forum, not the ask the doc forum. levaeh, i'm sure a doctor will address your question soon.......
hon, you should go see a doctor. i understand your fear, i'm going for a biopsy on friday. i'm really new to all of this, just started a couple days ago on this site. unfortunately, no one can tell you what the problem is except a doc. i tried it myself in my post. the hardest thing is not knowing, having to wait and being afraid. you'll not get the peace of mind you need unless you find out what the cause is. i hope this helps, i know how bad the fear can be. i wished i could be of more help to you....
