A weird lump on the wall of my throat

Recently I just remembered about this lump that I've found on the wall of my throat about 2 years ago, now it's still there and about the same size. The surface of the lump is about as big as the surface of a pennie, it's not completely flat and it hasn't caused much problem around that area aside from bad breathe and smell that I can smell with my own nose at times. Sometimes I can get a whiff of a very strong and sweet smell, sometimes I can get a whiff of a very bad foul smell. I was thinking that this could be a tumor, if anybody knows what this lump could be, please help!

I also uploaded a picture, hope this helps.
