My wisdom teeth have not come in yet, they were supposed to 3 years ago, my throat itches and I always have a stuffy nose. You may have a
deviated septum and that causes the nose and throat stuff. As for you having cancer, trust me they would know by your blood work. My friend had no problems no signs, went to the doctor for an after college check up and to do a CBC and other blood work, his numbers for everything came back off the chart. They would know if its cancer.
