Brain tumor – metastatic (secondary); Cancer – brain tumor (metastatic)
Definition of Metastatic brain tumor
A metastatic is cancer that started in another part of the body and spread to the brain.
Causes, incidence, and risk factors
Many tumor or cancer types can spread to the brain, the most common being lung cancer, breast cancer, melanoma, kidney cancer, bladder cancer, certain sarcomas, and testicular and germ cell tumors. Some types of cancers only spread to the brain infrequently, such as colon cancer, or very rarely, such as prostate cancer.
Signs and tests
An examination reveals neurologic changes that are specific to the location of the tumor. Signs of increased pressure within the skull are also common. Some tumors may not show symptoms until they are very large. Then, they suddenly cause rapid decline in the person’s neurologic functioning.
Treatment depends on the size and type of the tumor, the initial site of the tumor, and the general health of the person. The goals of treatment may be relief of symptoms, improved functioning, or comfort.
In general, the probable outcome is fairly poor. For many people with metastatic brain tumors, the cancer spreads to other areas of the body. Death often occurs within 2 years.
