Brain Tumor Awareness Month
May is Brain Cancer Awareness Month. Each year more than 23,000 people in the United States are diagnosed with brain cancer and other nervous system cancers, according to federal statistics. These cancers make up a portion of the nearly 78,000 brain tumors diagnosed each year in this country.
Tumors that start in the brain are called primary brain tumors. Primary brain tumors may spread to other parts of the brain or to the spine, but rarely spread to other parts of the body. Often, tumors found in the brain have started somewhere else in the body and spread to one or more parts of the brain. These are called metastatic brain tumors. Metastatic brain tumors are more common than primary brain tumors. About half of metastatic brain tumors are from lung cancer.
