I have this same problem. But mine is located on the corner of the Jaw, under the left ear..... It freaks me out cuz I have had a problem with a fibroid cyst in the left breast back in 2001. I had that removed. Now along with the Jaw defect. I have something that the description, well it matches the definition of a Chest Wall Tumor. I have no clue what it is & how would I get it fixed when I don't have Ins. ?View Thread
