10) Bleeding in the mouth
Bleeding can occur due to mouth sores or low platelet count. Unexplained bleeding in the mouth is a genuine warning sign of mouth cancer. You should rush to the hospital if the bleeding continues for more than half an hour or you start feeling dizzy. Bleeding can occur due to low platelet count in patients receiving treatment for mouth cancer, e.g. radiations. Your doctor may order a complete blood report to evaluate your condition further.
