The term bronchial adenoma describes a diverse group of tumors arising from mucous glands and ducts of the trachea (windpipe) or bronchi (large airways of the lung). This term describes all of the following types of tumors: neuroendocrine tumors (carcinoids), adenoid cystic carcinomas (cylindromas), mucoepidermoid carcinomas, mucous gland adenomas, and other mixed seromucinous tumors arising from mucous glands and ducts of the windpipe and large airways.
These tumors are of widely variable malignant (cancerous) potential, although most of them are low-grade malignancies, growing and spreading much more slowly than true lung cancer. Only mucous gland adenomas are truly benign (noncancerous), lacking even the potential to turn malignant.

Bronchodilators
Bronchodilators are medicines that help open the bronchial tubes (airways) of the lungs, allowing more air to flow through them.
Bronchoscopy allows a doctor to examine inside your airway for any abnormality such as foreign bodies, bleeding, a tumor, or inflammation. The doctor uses either a rigid bronchoscope or flexible bronchoscope.
Respiratory System, in anatomy and physiology, organs that deliver oxygen to the circulatory system for transport to all body cells. Oxygen is essential for cells, which use this vital substance to liberate the energy needed for cellular activities.
