My daughter just finished antibiotics for swollen glands and sore throat. She started complaining again. I brought her to the Dr. and her glands are very large and her throat looks bad again. She also has lost 3lbs. in two weeks. They did a monospot on her and it was positive right away. The problem is she had mono when she was 4. She has also had negative mono test in the past. Do you think there is more to the positive ( cancer)??
