D15: Benign neoplasm of other and unspecified intrathoracic organs
D15.0: Benign neoplasm: Thymus
When there is abnormal growth of tissue, then this is also referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant. The tumor you have is benign. Benign tumors do not destroy the healthy tissue and do not spread throughout the body.
The thymus gland is a small organ which forms part of the immune system. The thymus gland lies below the neck and is partly surrounded by the lungs. Immune cells mature in the thymus gland. The thymus gland is at its largest in children and adolescents. Later in life, the thymus gland gradually shrinks since it is no longer required.
