Despite advances in medical science, news about brain cancer incidence is not pleasant. The incidence of brain cancer is estimated at 20 cases per 100,000 people. Every year, in the United States, at least 19.000 people are diagnosed with primary brain cancer and 100.000 with secondary brain cancer. Primary brain cancer alone causes approximately 13.000 deaths each year.
According to the National Cancer Institute (NCI), it is estimated that 22,070 men and women (12,010 men and 10,060 women) were diagnosed with cancer of the brain and other nervous system in 2009; about 12,920 people died of it.
