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. Sometimes cells in the adrenal cortex change and become cancerous. This type of cancer is called adrenocortical carcinoma.
A pituitary tumor is an abnormal growth in the pituitary gland. The pituitary is a small gland at the base of the brain. It regulates the body's balance of many hormones. Most pituitary tumors are noncancerous (benign). Up to 20% of people have pituitary tumors. Many of these tumors do not cause symptoms and are never diagnosed during the person's lifetime. The pituitary gland is a pea-sized endocrine gland located at the base of the brain. The pituitary helps control the release of hormones from other endocrine glands, such as the thyroid, sex glands (testes or ovaries), and adrenal glands.
