The incidence of brain tumors

Research by American scientists confirm that the detected annually in the U.S. up to 40,000 new cases of cancer of the brain. Almost half of these tumors - is the primary tumor, and the rest - metastatic (ie, secondary).


Brain tumors can occur at any age. In fact, brain tumors are the second most frequent cause of death from cancer in people under the age of 35 years. In this case a small peak of deaths occur in the age category of 6 to 9 years. Still, most brain tumors have been reported in middle-aged and elderly. The greatest risk in this case is typical for the age over 60 years. Each year, about 1 in 5,000 people in this age group falls ill brain tumor.

Tumors of the spinal cord occur, for example, less than a brain tumor. Each year up to 10,000 U.S. residents fall ill primary or secondary tumors of the spinal cord. In addition, spinal cord tumors may occur in people of any age group, but more often they occur in young and middle age.

By studying the epidemiology of CNS tumors, researchers can learn which types of tumors are characterized for different age groups. In turn, these data help to identify the factors that influence the occurrence of certain tumors.
