I had a lump removed from my left breast in 2008, and now the same breast is hurting me again, could it be another lump.?

Yes. A dangerous breast lump (i.e., cancer / precancer) is seldom painful. If there is a dominant lump in your breast, a physician's office visit is indicated at once. Mere discomfort around an old operative site is something you should mention at your next annual physical exam.
