How can hormone therapy help with treating prostate cancer?
When used with other treatments, hormone therapy can:
- Make a tumor smaller before surgery or radiation therapy. This is called neoadjuvant therapy.
- Lower the risk that cancer will come back after the main treatment. This is called adjuvant therapy.
- Destroy cancer cells that have returned or spread to other parts of your body.
Why does hormone therapy worsen some prostate cancers?
Why does hormone therapy worsen some prostate cancers?

Can prostate cancer spread while on hormone therapy?
In 85% to 90% of cases of advanced prostate cancer, hormone therapy can shrink the tumor. However, hormone therapy for prostate cancer doesn't work forever. The problem is that not all cancer cells need hormones to grow. Over time, these cells that aren't reliant on hormones will spread.
What is the success rate of hormone therapy?
Hormone replacement therapy users had a 100% survival rate at 6 years as opposed to 87% in nonusers. Both groups of tumors were detected by screening mammography, thus detected "early" by current convention. Yet, we observed a survival benefit for those women who had received HRT.
What are the risks of hormone therapy?
Stroke, blood clots, and heart attack. Women who took either combined hormone therapy or estrogen alone had an increased risk of stroke, blood clots, and heart attack (1, 2). For women in both groups, however, this risk returned to normal levels after they stopped taking the medication (3, 4).

Does testosterone help prostate cancer?
Most prostate cancer cells rely on testosterone to help them grow. Hormone therapy causes prostate cancer cells to die or to grow more slowly. Hormone therapy for prostate cancer may involve medications or possibly surgery to remove the testicles. Hormone therapy for prostate cancer is also known as androgen deprivation therapy.
What is the most common treatment for prostate cancer?
Treatments that reduce androgen production by the testicles are the most commonly used hormone therapies for prostate cancer and the first type of hormone therapy that most men with prostate cancer receive. This form of hormone therapy (also called androgen deprivation therapy, or ADT) includes:
How do androgens help prostate cells grow?
Androgens promote the growth of both normal and cancerous prostate cells by binding to and activating the androgen receptor, a protein that is expressed in prostate cells ( 1 ). Once activated, the androgen receptor stimulates the expression of specific genes that cause prostate cells to grow ( 2 ).
What does it mean when your PSA is high?
An increase in PSA level may indicate that a man’s cancer has started growing again. A PSA level that continues to increase while hormone therapy is successfully keeping androgen levels extremely low is an indicator that a man’s prostate cancer has become resistant to the hormone therapy that is currently being used.
What hormones are released when androgen levels are low?
Normally, when androgen levels in the body are low, the hypothalamus releases LHRH. This stimulates the pituitary gland to produce luteinizing hormone, which in turn stimulates the testicles to produce androgens. LHRH agonists, like the body’s own LHRH, initially stimulate the production of luteinizing hormone.
What hormones block androgen production?
block androgen production (synthesis) throughout the body. Androgen production in men. Drawing shows that testosterone production is regulated by luteinizing hormone (LH) and luteinizing hormone-releasing hormone (L HRH). The hypothalamus releases LHRH, which stimulates the release of LH from the pituitary gland.
What does LHRH do to the testicles?
LHRH agonists, like the body’s own LHRH, initially stimulate the production of luteinizing hormone. However, the continued presence of high levels of LHRH agonists actually causes the pituitary gland to stop producing luteinizing hormone. As a result, the testicles are not stimulated to produce androgens.
What is the procedure to remove testicles?
This form of hormone therapy (also called androgen deprivation therapy, or ADT) includes: Orchiectomy, a surgical procedure to remove one or both testicles. Removal of the testicles, called surgical castration , can reduce the level of testosterone in the blood by 90% to 95% ( 5 ).
What hormones are used to treat prostate cancer?

Depression. Elevated cholesterol levels. Most men on hormone therapy experience at least some of these side effects. Before beginning hormone therapy, you should discuss the effects of testosterone loss with your doctor to help minimize them.

What is the surgical removal of the testicles?
