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.
