The spine is made up of strong bones called vertebrae. A vertebra can break just like any other bone in the body. When the vertebral body collapses, it is called a vertebral compression fracture. These fractures happen most commonly in the thoracic spine (the middle portion of the spine), particularly in the lower part.
When cells in the adrenal cortex become abnormal, they can form non-cancerous, or benign, tumours called adrenal cortical adenoma. Sometimes cells in the adrenal cortex change and become cancerous. This type of cancer is called adrenocortical carcinoma.It is the most common cancerous tumour of the adrenal gland. Tumours can also start in the medulla of the adrenal gland. When chromaffin cells in the medulla become abnormal, they can lead to a tumour called pheochromocytoma.Most pheochromocytomas are non-cancerous, but some are likely to become cancerous.hen cells in the adrenal cortex become abnormal, they can form non-cancerous, or benign, tumours called adrenal cortical adenoma.

Most pituitary tumors begin in the larger, front part of the pituitary gland known as the anterior pituitary. This part of the gland makes several hormones that control other endocrine glands. 1  Growth hormone (GH, also known as somatotropin) promotes body growth during childhood.2  If too much is made in a child they will grow very tall.his part of the gland makes several hormones that control other endocrine glands. 1  Growth hormone (GH, also known as somatotropin) promotes body growth during childhood. 2  If too much is made in a child they will grow very tall.
