I have a lump on the side of my nose. Is my nose just asymmetrical or could I have nasal cancer? (photo)

On the left side of my nose I have a soft 'lump' which is not very noticeable but I am able to feel it. It is not inside the nose but rather under the skin. I had also had a nose piercing at the age of 18 (I am now 42). The right side of my nose is flat and straight, whereas the other side is 'swollen'.
