Causes of Brain cancer
The exact cause of cancer remains unknown. Is called a primary brain tumor that starts in the brain itself. It can spread to surrounding areas of the brain and destroy them. Breast cancer, lung, skin, or blood cells (leukemia or lymphoma) can also spread (metastasize) to the brain, causing metastatic brain cancer. These groups of cancerous cells may then multiply in a single region or in different parts of the brain.
Symptoms and Complications
Brain cancer causes symptoms when it pushes on the brain that destroys brain tissue. Symptoms depend on the size and location of the tumor, and the speed at which it multiplies. Although headaches are often a symptom of brain cancer, it is important to remember that most headaches are not caused by cancer but are caused by less serious conditions such as migraine or tension. Headaches caused by brain tumors are often severe, associated with nausea and vomiting and often worse early in the day. They can last long or occur intermittently.
Other symptoms include:
* Dizziness
* Impaired vision as double vision
* Impaired coordination
* Weakness or numbness on one side of body
* Seizures
* Changes in mood, senses, personality or feelings
* A state of confusion or difficulty concentrating
