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 brain tumor is an abnormal growth of tissue in the brain. Unlike other tumors, brain tumors spread by local extension and rarely metastasize (spread) outside the brain. A benign brain tumor is composed of non-cancerous cells and does not metastasize beyond the part of the brain where it originates.A brain tumor is considered malignant if it contains cancer cells, or if it is composed of harmless cells located in an area where it suppresses one or more vital functions.. A brain tumour is any intracranial tumor normally either in the brain itself in the cranial nerves, in the brain envelopes, skull, pituitary and pineal gland, or spread from cancers primarily located in other organs (metastatic tumors).
