10 Symptoms of Carcinoid Tumor

8. Cough

The tumor may originate from the lungs. In this case, the carcinoid tumor will cause the affected patient to cough. The person may even start to cough blood. Many people also complain that it becomes difficult for them to breathe. They feel pain in their chest, and they feel tired all the time. Even if the carcinoid tumor develops outside the lung, it can still produce respiratory symptoms like wheezes. These symptoms are caused by the different chemicals that can make the passage of the airways narrower.
