Most prostate cancers depend on the male hormone testosterone for their growth. Removing testosterone, or blocking its action, causes prostate cancer cells to regress. This is generally referred to as hormonal therapy but correctly called Androgen Deprivation Therapy (ADT). Unfortunately, resistant cells eventually develop which can survive and grow in the absence of testosterone. ADT can very effectively improve symptoms and quality of life. As well, ADT may also prolong life. ADT is generally used in the treatment of more advanced prostate cancer, but may be useful in combination with surgery or radiation.
ADT can be achieved in a variety of ways:
- Surgical removal of the testes.
- Medications that cause the testicles to stop making testosterone.
