Hormone therapy for prostate cancer
Androgens, such as testosterone, are male hormones that encourage cancer cells to grow. Also known as androgen deprivation therapy (ADT), this treatment lowers the level of androgens in your body.
Although hormone therapy doesn’t cure prostate cancer, it helps slow its growth or shrink a tumor, allowing other treatments, such as radiation therapy, to be more effective.
You may benefit from ADT if your cancer returns after treatment. ADT is also an option if your cancer spreads so far beyond the prostate that surgery or radiation is not a good treatment option.
Hormone therapy options include:
- Medications to lower testosterone levels: LHRH agonists shrink testicles and reduce testosterone production. Administered via injection or implants every 1-6 months, they provide medical castration but may initially increase testosterone levels.
- Medications to lower or stop androgen production: Anti-androgens block androgens from promoting cancer growth. These daily oral medications connect to androgen receptors, preventing androgens from growing cancerous tumors. Multiple options are available for effective treatment.
- Orchiectomy: The goal of orchiectomy is the same as hormone therapy. This surgical procedure removes the testicles to reduce androgen levels, potentially slowing cancer growth or shrinking tumors. Artificial testicles can be used for a natural appearance.
