Testicular cancer future or investigational therapies

Surveillance
For stage I cancers that have not had any adjuvant (preventive) therapy, close monitoring for at least a year is important, and should include blood tests (in cases of nonseminomas) and CT-scans (in all cases), to ascertain whether the cancer has metastasized (spread to other parts of the body). For other stages, and for those cases in which radiation therapy or chemotherapy was administered, the extent of monitoring (tests) will vary on the basis of the circumstances, but normally should be done for five years (with decreasing intensity).

Fertility
A man with one remaining testis can lead a normal life, because the remaining testis takes up the burden of testosterone production and will generally have adequate fertility. However, it is worth the (minor) expense of measuring hormone levels before removal of a testicle, and sperm banking may be appropriate for younger men who still plan to have children, since fertility may be lessened by removal of one testicle, and can be severely affected if extensive chemotherapy and/or radiotherapy is done.

Less than five percent of those who have testicular cancer will have it again in the remaining testis. A man who loses both testicles will normally have to take hormone supplements (in particular, testosterone, which is created in the testicles), and will be infertile, but can lead an otherwise normal life.
