Bilateral testicular cancer.

Although the case we described is not common, the incidence of testicular cancer, as well as bilateral testicular cancer, is rising. The primary care physician can help reduce morbidity in these patients by encouraging monthly self-examinations of the testicles and by paying attention to high-risk subgroups, such as those with a family history of testicular cancer, a personal history of cryptorchidism, infertility, or a contralateral testicular volume less than 12 mL. The primary care physician should, in at least these cases, discuss the option of a testicular biopsy to rule out CIS in the contralateral testicle. Treatment and follow-up options can then be explored to reduce further sequelae from this disease.
