@ddljohn-- Did your doctor tell you which class your LSIL is in?
The pap smear test results are classified into five different categories. Class I is a normal result. Class II is mild dysplasia which means that cells are abnormal but there is no growth (low risk for cancer). Dysplasia is the term used for abnormally sized and shaped cells.
Class III classification is moderate dysplasia which means that new cells are growing in an abnormal manner (moderate risk for cancer). Class IV is "carcinoma in situ" which is cancer that has not spread but remained in the location where it started. Finally Class V is invasive cancer, or cancer which has spread.
The fact that your doctor asked you to come back in 6 months for another pap smear means that you must be in either level II or level III. If you were in another level, you would have definitely been kept for more testing.
You should get the HPV testing done in the meantime to find out if that's the reason for your abnormal pap. And don't miss your second pap smear. From your description, it doesn't appear that there is much to worry about. Sometimes doctors are busy and don't go through all the details, don't be afraid to call your doctor up for a more detailed conversation.
