Signs of Maxillary Sinus Tumors
Maxillary sinuses are glands located behind our cheekbones. Occurrence of tumors in the maxillary sinuses is common. According to the definition presented by the National Cancer Institute, tumors are masses consisting of extra tissues, which are formed with newly produced cells that are created without any need. Tumors can be benign or malignant. A benign tumor is usually not known for causing any health issue. A person will suffer from severe health problems due to benign tumors only if these tumors impede the sinus drainage or block the airflow. The malignant tumors, on the other hand, are formed of cancerous cells. As the disease progresses, the malignant tumor in the maxillary sinuses tends to spread outside the sinus glands affecting tissues of other body parts.
