According to a recent study sponsored by Cancer Care Ontario in Canada and the Centers for Disease Control in the US, the number of cases of testicular cancer increased by nearly 60 percent between 1964 and 1996. The exact reasons for the increase in incidence are not yet known. The American Cancer Society estimates that testicular cancer will be diagnosed in 7,400 men in 1999. In spite of statistics showing increased incidence in the number of cases, testicular cancer is usually successfully treated.
More men die of breast cancer each year than die of testicular cancer.
