all primary benign and malignant brain tumors* is 11.5 cases per 100,000
person-years. The rate is higher in males (12.1 per 100,000 person-years)
than females (11.0 per 100,000
person-years).1

The incidence rate of all primary benign brain tumors
is 4.6 per 100,000
person-years.1

An estimated 34,345 new
cases of primary benign and malignant brain tumors were expected to be diagnosed
in 1998.1

The incidence rate of
primary malignant brain tumors is 5.8 cases per 100,000 person-years. This
rate is higher in males (7.0 per 100,000 person-years) than females (4.7

in 1998 were attributed to primary malignant brain
tumors.2b |

chance of dying from a brain
tumor.2c

lifetime risk of being diagnosed with a primary malignant brain tumor and
a 0.38% chance of dying from a brain
tumor.2c |
Survival

The five-year relative
survival rate following diagnosis of a primary malignant brain tumor (excluding
lymphoma) is 26.6% for males and 27.9% for
females.3
