Brandy...First of all, remember that about 80% of all lumps are benign (non-cancerous).
Next, let me ask you a couple of questions...
1. When you press on it, does it feel like a round ball (like a grape, rubber ball, or eyeball)?
2. Does it move when you push on it, or is it stuck in place?
3. Do you have any redness or itching on the outside?
