Clinical Trials for Brain Metastases
What is a Metastatic Brain Tumor?
Brain metastases, or ‘secondary’ brain tumors, originate from cancer in another part of the body. Up to 40 percent of systemic cancer patients develop brain metastases. These tumors can present as solitary masses or as multiple lesions in the brain. As metastatic brain tumors grow, they create pressure on and change the function of surrounding brain tissue. Any cancer can spread to the brain, but the most common sources of brain metastases are cancers from the lung, breast, colon, kidney, and skin.
Brain Tumor Symptoms
Brain tumor symptoms vary widely depending on the type, location, size and growth rate of the tumor. There is no set of symptoms that are attributable to a single type of brain tumor.
General symptoms of brain tumors include:
- New onset or change in pattern of headaches
- Headaches that gradually become more frequent and more severe
- New onset of seizures
- Gradual loss of sensation or movement in an arm or a leg
- Difficulty with balance
- Difficulty speaking
- Personality or behavior changes
- Unexplained nausea or vomiting
- Blurred vision, double vision, or loss of peripheral vision
- Hearing problems
Contact your physician if you have a recent history of cancer and are experiencing any of these symptoms.
