My sister just underwent surgery for abnormal cervical cells, upon biopsy she was told that the outer cervix tested negative but her inner cervix tested positive for abnormal cells. She was told to wait 3 months and get reassessed and see if the situation improves and if not contact an oncologist. She's very young, 26, and I worry that waiting could cause the abnormal cells to spread into a more aggressive cancer. Should she get a second opinion or trust that 3 months will not change anything?
