Testicular cancer is a malignancy that most commonly originates in the germ cells of 1 or both of the testicles.1,2 Although rare, testicular cancer is one of the most frequently diagnosed cancers in young adult men between the ages of 30 and 39 years.1 For reasons that have yet to be identified, the incidence rates for testicular cancer has been on the rise for the past several decades, although this increase in rates has slowed in recent years.1 According to the American Cancer Society, approximately 9910 men in the United States will be diagnosed with testicular cancer in 2022, and approximately 460 will die from the disease.1 How much do you know about testicular cancer?
Testicular cancers that originate in germ cells can be classified as seminomas or nonseminomas.1 Seminomas, which grow and spread slowly, can be subclassified as classical or spermatocytic. Classical seminomas comprise >95% of cases and are usually diagnosed in men aged 25 to 45 years. Spermatocytic seminomas, which are less common, are typically diagnosed in men aged >65 years.1,2 Nonseminomas, which tend to grow and spread more quickly than seminomas, are usually diagnosed in men in their late teens to early 30s.2 The overall 5-year survival rate for testicular cancer is 95%; 99% for localized disease, 96% for regional disease, and 73% for distant disease.2 Public awareness of the disease needs to remain a priority to improve survival rates and patient quality of life.
