Abnormalities discovered in a pap test

DEAR ASK THE DOCTOR: I went for my regular pap test last february and the results came back abnormal.  I was referred to a specialist 6 months later who then performed another pap and took a biopsy sample.  At the follow up appointment with the specialist she said the last results came back fine but wanted to repeat the procedure to be sure.  I just recieved a call from her office stating that there were still abnormal cells and she is sending me for a second opinion.  Should I be concerned about going to another doctor?  Why is she sending me for a second opinion?  What kind of abnormalities would show up?
