What are the side effects of prostate hormone therapy?
Current issues in hormone therapy. Hormone therapy is also called androgen suppression therapy. The goal is to reduce levels of male hormones, called androgens, in the body, or to stop them from fueling prostate cancer cells. Androgens stimulate prostate cancer cells to grow. The main androgens in the body are testosterone and dihydrotestosterone (DHT).
What hormone is responsible for prostate cancer?
Hormone therapies, which are treatments that decrease androgen levels or block androgen action, can inhibit the growth of such prostate cancers, which are therefore called castration sensitive, androgen dependent, or androgen sensitive.
What drugs cause prostate cancer?
Does hormone therapy stop prostate cancer from spreading? 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 medications stop the body from producing testosterone?
Certain medications — known as luteinizing hormone-releasing hormone (LHRH) or gonadotropin-releasing hormone (GnRH) agonists and antagonists — prevent your body's cells from receiving messages to make testosterone. As a result, your testicles stop producing testosterone.
What is the best way to block testosterone from cancer cells?
Anti-androgens block testosterone from reaching cancer cells. These oral medications are usually prescribed along with an LHRH agonist or before taking an LHRH agonist.
What is the medication that blocks testosterone from reaching cancer cells?
Medications that block testosterone from reaching cancer cells. These medications, known as anti-androgens, usually are given in conjunction with LHRH agonists. That's because LHRH agonists can cause a temporary increase in testosterone before testosterone levels decrease.

Side effects of hormone therapy for prostate cancer can include: Loss of muscle mass. Increased body fat. Loss of sex drive. Erectile dysfunction. Bone thinning, which can lead to broken bones. Hot flashes. Decreased body hair, smaller genitalia and growth of breast tissue. Fatigue.
What happens after prostate cancer treatment?
After treatment of prostate cancer, if the prostate-specific antigen (PSA) level remains high or starts rising. In locally advanced prostate cancer, to make external beam radiation therapy more effective in reducing the risk of recurrence. In those with a high risk of recurrence after initial treatment to reduce that risk.
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.
Where is prostate cancer located?
Prostate cancer occurs in the prostate gland, which is located just below the bladder in males and surrounds the top portion of the tube that drains urine from the bladder (urethra). This illustration shows a normal prostate gland and a prostate with a tumor.
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 is the risk of prostate cancer recurrence?
Early-stage prostate cancer with an intermediate or high risk of recurrence. Men with early-stage prostate cancer that has an intermediate or high risk of recurrence often receive hormone therapy before, during, and/or after radiation therapy, or after prostatectomy (surgery to remove the prostate gland) ( 7 ). Factors that are used to determine the risk of prostate cancer recurrence include the grade of the tumor (as measured by the Gleason score ), the extent to which the tumor has spread into surrounding tissue, and whether tumor cells are found in nearby lymph nodes during surgery.
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 inhibit prostate cancer?
Early in their development, prostate cancers need androgens to grow. Hormone therapies, which are treatments that decrease androgen levels or block androgen action, can inhibit the growth of such prostate cancers, which are therefore called castration sensitive, androgen dependent, or androgen sensitive.
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 is the flare of LHRH?
When patients receive an LHRH agonist for the first time, they may experience a phenomenon called " testosterone flare ." This temporary increase in testosterone level occurs because LHRH agonists briefly cause the pituitary gland to secrete extra luteinizing hormone before blocking its release. The flare may worsen clinical symptoms (such as bone pain, ureter or bladder outlet obstruction, and spinal cord compression ). The increase in testosterone is usually countered by giving another type of hormone therapy, called antiandrogen therapy, along with the LHRH agonist for the first few weeks of treatment.
What does it mean when your PSA is low?
Undetectable or low PSA levels usually mean that the treatment is working . If your PSA levels go up, it’s a sign that the cancer has started growing again. If this happens, your cancer is considered castrate-resistant, and hormone deprivation therapy is no longer an effective treatment.

If this happens, your cancer is considered castrate-resistant, and hormone deprivation therapy is no longer an effective treatment.

Huggins found that some types of prostate cancer cells need certain male hormones -- called androgens -- to grow. Androgens are responsible for male sexual characteristics, like facial hair, increased muscle mass, and a deep voice. Testosterone is one kind of androgen.
