Definition of Brain Cancer

Brain cancer is a disease of the brain where the cancer cells (hazardous) growing in the brain tissue. Cancer cells grow to form a mass of cancerous tissue (tumor) that interferes with brain tissue functions such as muscle control, sensation, memory, and normal body functions other. Tumors composed of cancer cells called tumors hazard (malignant), and are composed of cells that are not cancer (noncancerous) are called benign tumors (benign). Cancer cells that develop from brain tissue are called primary brain tumors. These statistics suggest that brain cancer is not uncommon and likely growing at roughly 20,000 people per year.

Definition of Brain Cancer metastatic

Cancer cells that develop in organs such as lung (type of primary cancer tissue) can go to other body organs like the brain. Tumors formed by cancer cells as it is spread (metastasize) to other organs is called metastatic tumors. Metastatic brain tumor is a mass of cells (tumor) derived from other organs and has spread into the brain tissue. Metastatic tumors in the brain are more common than primary brain tumors.

Causes of Brain Cancer

Primary brain tumors arise from many types of brain tissue (eg, glial cells, astrocytes, and brain cell types other). Metastatic brain cancer is caused by the spread of cancer cells from organs to the brain. However, the causes for the change of normal cells into cancer cells in both tumor-metastatic and primary tumors are not completely understood. Data collected by scientists showed that people with certain risk factors (situations or things that relate to those that increase the likelihood of developing problems) were more likely to develop brain cancer.

Individuals with risk factors such as having a job at oil refineries, such as chemists, who embalm, or the rubber industry workers showed brain cancer rates are higher. Some families have several members with brain cancer, but heredity as a cause for brain tumors has not been proven. Other risk factors like smoking, radiation exposure, and viral infections (HIV) has been suggested but not proven to cause brain cancer. There is no strong evidence that brain cancer is contagious, caused by head trauma, or caused by the use of hp (cell phone).
