6 months after septoplasty and bump on septum is still present - can this be corrected? (photos)

I had septoplasty about 6 months ago and since then I've had a hard bump/lump on my nasal septum. It is probably protruding cartilage. When I went for a check up visit 2-3 weeks after the operation, my surgeon simply said that I should not worry about it. But although it doesn't impact my breathing, it is bothering me psychologically. Could this be easily fixed? I'm really irritated with this bump.
