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.

A brain tumor is an abnormal growth of tissue in the brain. If the tumor originates in the brain, it is called a primary brain tumor. Primary brain tumors can be benign or malignant. Benign brain tumors. Benign brain tumors are not cancerous.They grow slowly, have distinct borders and rarely spread. Benign tumors can still be dangerous, though. They can damage and compress normal parts of the brain, causing severe dysfunction.enign brain tumors are not cancerous. They grow slowly, have distinct borders and rarely spread.
