At what age is testicular cancer most frequently diagnosed?
I read on the National Cancer Institute site that the age testicular cancer is most often diagnosed is in men who are between 20 and 39 years of age. They also say that it's the most common type of cancer in men between the ages of 15 and 34, though it accounts for only 1 percent of all cancers in men in the U.S.
The American Cancer Society website expands the age when testicular cancer is most often diagnosed to include men between the ages of 20 and 54.
