Secondary (metastatic) brain tumors are tumors that result from cancer that starts elsewhere in your body and then spreads (metastasizes) to your brain.
Secondary brain tumors most often occur in people who have a history of cancer. But in rare cases, a metastatic brain tumor may be the first sign of cancer that began elsewhere in the body.
Secondary brain tumors are far more common than are primary brain tumors.
Any cancer can spread to the brain, but the most common types include:
Breast cancer
Colon cancer
Kidney cancer
Lung cancer
Melanoma
