How does a person get brain cancer?

Primary brain tumors begin when normal cells acquire errors (mutations) in their DNA. These mutations allow cells to grow and divide at increased rates and to continue living when healthy cells would die. The result is a mass of abnormal cells, which forms a tumor.

What is the main cause of brain tumor?

The exact cause of brain cancer is unknown. However, factors that can increase your risk of brain cancer include exposure to high doses of ionizing radiation and a family history of brain cancer. Cancer in another part of your body is also a risk factor.

What is the only known risk factor for brain tumors?

The best known environmental risk factor for brain tumors is radiation exposure, most often from radiation therapy to treat some other condition.

What age group does brain cancer affect?

Cancers of the brain occur in people of all ages, but are more frequent in two age groups, children under the age of 15 and adults 65 years of age and over. Cancers of the spinal cord are less common than cancers of the brain.

What are the main causes of brain cancer?

The exact cause of brain cancer is unknown. However, factors that can increase your risk of brain cancer include exposure to high doses of ionizing radiation and a family history of brain cancer. Cancer in another part of your body is also a risk factor.

How long before a brain tumor kills you?

All too often, it kills with appalling speed; the most common primary brain cancer in adults, glioblastoma multiforme, is also the deadliest. In the United States, only half of patients receiving the standard treatments survive for a year after diagnosis. Fewer than one in ten are alive five years later.

Can you get a brain tumor from stress?

Stress Triggers Tumor Formation, Yale Researchers Find. Stress induces signals that cause cells to develop into tumors, Yale researchers have discovered. Researchers in the Xu lab previously showed that a combination of the two within the same cell could trigger malignant tumors.

How quickly do brain tumors grow?

Higher radiation doses are generally felt to increase the risk of eventually developing a brain tumor, and radiation-induced brain tumors can take anywhere from 10-30 years to form.

Can brain tumor be cured?

Grade I brain tumors may be cured if they are completely removed by surgery. Grade II — The tumor cells grow and spread more slowly than grade III and IV tumor cells. They may spread into nearby tissue and may recur (come back). Grade IV tumors usually cannot be cured.

Are there any early detection signs of brain cancer?

Some symptoms can be quite general. These include headaches, vision problems, and mood changes. Seizures and personality changes can also signal the presence of a brain tumor. If a person notices any early symptoms of a brain tumor, they should speak to their doctor for a thorough diagnosis.
