I have a lump on my left tibia. Hard lump. I had it xrayed and then just had an MRI. They called it soft tissue density lump. I have had more bone aches in other areas...especially buttocks, shoulders, and leg. The tibia hurts if I kneel on it and sometimes I get shooting pains. It is tolerable but I an concerned what this growing lump is. I don't know yet if it is cancer.
