Hormone Treatment For Prostate Cancer

What Are The Treatments For Prostate Cancer?

Hormone therapy treatment for prostate cancer is designed to eliminate the male hormones (androgens) from the body. Androgens are necessary for the development and function of the male sexual organs and male sexual characteristics such hair growth and voice changes.

Proper Care

Androgens are primarily produced by the testicles, under control of various parts of the brain. A small amount of androgens is produced by the adrenal glands, which are small glands located above the kidneys and which produce many important chemicals. The most common androgen is testosterone.

Prostate cancer cells may be hormone sensitive, hormone insensitive, or hormone resistant. Cancer cells that are hormone sensitive require androgens for growth.  Therefore hormone therapy for the treatment of prostate cancer only works in the former case.

It is important to note that hormone therapy treatment for prostate cancer does not eliminate prostate cancer cells, but rather it is “palliative therapy” in that its goal is to slow down the progression of prostate cancer. Hormone treatment for early stage prostate cancer, or hormone therapy for patients with metastatic disease may work effectively for several years. However over time, hormone-resistant cells will emerge, and the cancer will grow.

When Is Hormone Therapy For Prostate Cancer Used?

Hormone treatment for prostate cancer may be used as a primary, secondary, or neoadjuvant therapy. Hormone therapy for the treatment of prostate cancer is often used as a primary therapy in older men who are not candidates for surgery or radiation therapy and who are not interested in watchful waiting. It is also used in men who have metastatic disease at the time their prostate cancer is detected.

Men who experience a rise in their PSA after radical prostatectomy, radiation therapy, or cryotherapy are given hormone therapy to slow down the growth of the recurrent prostate cancer. Hormone therapy may be given for a period of time before radical prostatectomy or radiation therapy to shrink the prostate gland and make the procedure easier to perform. This is referred to neoadjuvant therapy.

Hormone treatment for prostate cancer comes with side effects such as fatigue, loss of libido, erectile dysfunction and even osteoporosis. Discuss with your doctor on what to expect, and research for ways to cope with the side effects before you undergo treatment.

Risk Factors Which Have Little Effect On Prostate Cancer

What Cause Prostate Cancer?

There have been many attempts to establish links between various factors and the risk for prostate cancer. The factors listed below are what many would think are risk factors for prostate cancer, but in reality they have little or no effect on the risk for developing prostate cancer.


A vasectomy is a surgical procedure performed to make a man infertile. Some studies have suggested that men who had a vasectomy before the age of 35 may have a slightly increased risk for prostate cancer.

However, results of studies to establish this link have been mixed and are not strong enough to warrant recommendation that men wait to have this procedure or reverse the procedure.


As cigarette smoke contains cancer-causing chemicals (also called carcinogens), some scientists thought smoking may be a risk factor of prostate cancer. In reality, smoking increases your risk of developing lung cancer, as well as other cancers, such as prostate cancer.

Although men who smoke may have a higher mortality rate from prostate cancer than non-smokers, evidence does not suggest a link between smoking and the development of prostate cancer. Smoking has been clearly linked to other illnesses including cancers of the lung, mouth, throat, bladder, kidney, pancreas, and stomach, as well as heart disease, pneumonia, cataracts, and a serious from of gum disease called periodontitis.

Sexual Activity

 This leads to many men asking if a man’s level of sexual activity has any impact on his risk for developing prostate cancer.

Different groups of men have been studied in an effort to establish if sexual activity is a prostate cancer risk factor. Studies on married men with or without children, unmarried men with one or more sexual partners, young men, older men and so on did not provide any strong evidence of a relationship between sexual activity or inactivity and the risk for prostate cancer.

Viruses And Other Infections

Many viruses can infect the prostate, just as they can infect any other tissue in the body. Viral infections can cause inflammation and problems with urination.

However, there are few reports of these infections resulting in higher risk of prostate cancer. Recent studies have looked at a potential relationship between HPV infections in men and the risk of prostate cancer. However, results are inconclusive and more studies are expected to be conducted over the next few years.

Medical Prostate Cancer

Digital Rectal Examination Of The Prostate

A digital rectal examination of the prostate allows a doctor or experienced health care professional to determine if the prostate is enlarged, hard, or see if there are any irregularities in it. The digital rectal examination procedure also gives your doctor an idea of how extensive any abnormality of the prostate might be and helps the doctor to plan and direct a potential biopsy, in which a sample of tissue is removed and examined under a microscope. Additional testing can determine the cause of any abnormality.


The prostate gland is located just in front of the rectum, which means that part of it can be felt through the rectum. The doctor gently places a gloved, lubricated finger into the rectum to feel the part of the prostate that is just under the skin of the rectum. A digital rectal examination (DRE) should be performed as part of any screening process for prostate cancer and should be performed by a physician, physician’s assistant, or nurse practitioner who is experienced in performing these procedures.

A digital rectal examination can help detect both prostate and rectal cancer. The digital rectal examination and standard screening is often part of a thorough physical examination of an adult man. The DRE is also used after a man is diagnosed with prostate cancer to help determine if the cancer has spread beyond his prostate gland and is used to detect cancer that has returned after treatment.

What Does A Digital Rectal Examination Involve?

The doctor may ask you to bend over the edge of the examination table or lie on the table on your side with your knees held close to your chest for this procedure. The procedure may cause some discomfort, but it is not painful and is usually very brief.

Why Is A Digital Rectal Examination Needed?

DRE and PSA testing are usually done together because neither test alone provides adequate testing for prostate cancer. About one fifth of prostate cancers do not produce enough PSA to make the blood PSA level abnomal. The PSA test therefore may not detect these cases.

DRE alone does not provide adequate screening for prostate cancer. It is difficult for a doctor’s finger to reach all parts of the prostate gland through the rectum, although it reaches the back part of the gland, where most prostate cancers begin. Small prostate cancers may be difficult to feel and therefore difficult to detect through DRE.

To give you a better idea of what is involved in a DRE, watch the digital rectal examination video by a doctor who explains what to expect from a DRE.

Three Ways To Prevent Prostate Cancer

How To Prevent Prostate Cancer?

Prostate cancer is influenced by a number of different factors. It is therefore not possible to identify a single reason why prostate cancer occurs. However, there are three ways to prevent prostate cancer or stop the prostate cancer from forming.

How You Can Prevent Prostate Cancer

1) Blocking The Effects Of Hormones

Hormones appear to play a role in the development of prostate cancer. High levels of androgens may encourage the development of prostate cancers in some men.

Finasteride (Proscar) and dutasteride (Avodart) are drugs that lower the body’s levels of a potent androgen called DHT. Both drugs are used to treat benign prostatic hyperplasia (BPH).

One large study found that finasteride reduced the risk of developing prostate cancer by about 25 percent. Men at risk for prostate cancer are encouraged to consult their doctors about how to prevent prostate cancer with the use of finasteride in their own situation.

2) Diet For Prevention Of Prostate Cancer

Some cases of prostate cancer might be prevented by altering potential risk factors such as diet. 

Men who eat a lot of red meat or who consume a lot of dairy products appear to have a greater chance of developing prostate cancer, including a more aggressive form of prostate cancer.

Eating five or more servings of fresh fruits and vegetables each day is also recommended. Fresh fruits and vegetables contain antioxidants which block the actions of free radicals that can damage cells.

Lycopene, an antioxidant, is believed to help prevent prostate cancer. High levels of lycopene can be found in tomatoes, pink grapefruit and watermelon.

Beans, along with whole-grain bread, cereals, wholemeal pasta and brown rice are other healthy dietary choices. Dietary soy such as tofu, soybeans or soy milk may also lower prostate cancer risk by inhibiting the growth of cancer cells.

Vitamins A, C, D and E, as well as the mineral selenium, actually reduce prostate cancer risk. Talk to your doctor before taking any dietary supplements or high-dose vitamins.

3) Exercise

The best way to prevent prostate cancer or any other disease is regular exercise. Although it has not been clearly established that regular exercise reduces a man’s risk of prostate cancer, keeping fit will help maintain a healthy weight and heart. Reducing body fat and lowering male hormone levels may indirectly lead to a reduction in prostate cancer risk.

Prostate Cancer Screening Guidelines And Tests

What Are The Test To Carry Out?

Since the early 1990s, the American Cancer Society and the American Urological Association have recommended two prostate cancer screening tests:

1) The Digital Rectal Examination (DRE)

This is a physical examination in which the doctor inserts his or her gloved finger into the rectum to detect any irregularity in the nearby prostate gland’s surface.

2) The Prostate-Specific Antigen (PSA) Test

This prostate cancer screening test is a blood test that measures levels of a protein made by the prostate. Prostate -specific antigen testing uses chemical methods to provide a PSA number indicating how much of the protein is in the blood.

A combination of both the DRE and PSA is most effective in finding prostate cancer. Screening for prostate cancer in men without symptoms can detect tumors at an earlier stage, allowing for earlier treatment and potentially more favorable results.

Prostate Cancer Screening Guidelines

  • It is recommended that a baseline screening be done at age 40 and possibly again at age 45 before beginning annual prostate cancer screening at age 50.
  • Annual prostate cancer screening is recommended after the age of 50 for men who have at least a 10-year life expectancy.
  • Men at high risk, such as African Americans and men who have a first-degree relative (father, brother or son) diagnosed with prostate cancer at an age younger than 65, should begin prostate cancer screening tests at age 45.
  • Men at even higher risk (with several first-degree relatives who had prostate cancer at an early age) could begin testing at age 40. If the results of this initial prostate cancer screening test are less than 1 ng/ml, further testing might not be needed until age 45.
  • Understand from your doctor the benefits, side effects and potential risks of PSA screening.
  • Ask questions regarding early prostate cancer detection and treatment so that you can make informed decisions about testing.
  • As discussed earlier, digital rectal examination (DRE) and Prostate-Specific Antigen (PSA) testing are most effective when used together to detect prostate cancer.
  • A PSA of less than 4.0 ng/ml does not mean that you do not have prostate cancer.
  • Conversely, an abnormal DRE or a high PSA level does not necessarily mean that you do have prostate cancer. Some elevations in PSA may be due to benign (not cancerous) conditions of the prostate. If you do have a PSA result of 4.0 ng/ml or higher, your doctor will work with you to determine the cause of this elevated PSA level.

Cause Of Prostate Cancer

Is Working The Graveyard Shift A Cause Of Prostate Cancer?

The causes of prostate cancer are hormone-dependent, just like breast cancer. While male and female hormones are crucial to prostate and breast cancer development respectively, female hormones also play a role in prostate cancer while male hormones also play a role in breast cancer.

Both cancers are also impacted by another hormone called melatonin, which is linked with the sleep-wakefulness cycle. A link between breast cancer in women and night shift work has been established. Working at night exposes women to light when they should be asleep in the dark. It is also believed that men working night shifts and exposed to “light pollution” may increase the risk of contracting prostate cancer.

At night, the body’s internal clock says it should be dark. But when exposed to light at night, the brain produces less melatonin. Melatonin serves a critical function in suppressing cancer formation in other organs at the gene level.


Melatonin ins produced in a tiny body located at the brain’s centre called the pineal gland. A grain-size group of neurons in the brain which serves as our internal clock tells the pineal gland to produce melatonin. This internal clock is reset by natural light outside that we encounter every morning on waking up.

This internal clock serves as our body’s chief biological pacemaker, synchonizing all our internal biorhythms, even at tissue and cellular levels, to a 24-hour circadian cycle. We human beings are active during the day and are programmed to sleep at night. Our bodily functions are timed so that the most important biorhythms such as alertness, metabolism and performance are optimal during the day, while sleep is optimal at night. DNA synthesis, healing, recovery and renewal occurs mainly at night.

The resetting of the internal clock takes place every morning when one wakes up and the eyes perceive natural sunlight outside. This natural light is the cue the pacemaker needs to tell the pineal gland to pace itself so it produces the most melatonin at night.

However, if the pineal gland is routinely stimulated by light at night, it might be tricked into turning down or even switching off its melatonin production. When this happens, all our bio-rhythms including those of our sex hormone levels and genes known to be controlled by circadian rhythms, become unregulated.

Over years of shift work, his kind of pacemaker resetting throws cellular biorhythms into disarray. In this way, the prostate in men and breasts in women may become more susceptible to cancer development. A link between light pollution and lymphoma has also been observed.

Body Checkup

About 10% of genes are directly subject to this chief pacemaker’s oversight. These circadian genes help to suppress cancer formation. In particular, the Per1 gene is known to inhibit the growth of prostate cancer cells. When the functioning of such genes is disrupted by light pollution, the bio-rhythms of sex hormone levels may also go awry. This may affect some other circadian genes as well. This could in turn cause prostate cancer.

Recent epidemiological studies in Japan and the United States suggest that workers who have to rotate shifts face a higher risk of prostate cancer compared to those who have day shifts only or night shifts only. In March 2009, the Danish government agreed to compensate 40 female nurses and flight attendants with breast cancer who had worked a night shift at least once a week for 20 years. It may be a matter of time that prostate cancer sufferers who have worked night shifts for years will also be eligible for compensation.

Medical Prostate Tests

The Prostate PSA (Prostate-Specific Antigen) Test

What Is Prostate PSA Test?

The prostate-specific antigen (PSA) test is commonly used to detect prostate cancer.  PSA liquefies semen so sperm are better able to travel up the female reproductive tract.

When the prostate is healthy, very little PSA escapes into the bloodstream. Sometimes, due to diseases or an enlarged prostate gland, the walls between the prostate and the bloodstream may break down and allow more PSA into the blood. PSA can be detected by a blood test.

The PSA Test

Abnormal levels of prostate-specific antigen often indicate that a man has prostate cancer. Testing for high PSA levels allows doctors to assess a man’s prostate cancer risk. Generally, when cancer is present, the higher the PSA level is, the larger the prostate cancer is and the more likely it is to have spread beyond the prostate.

However, the PSA levels alone do not provide enough information to distinguish between benign prostate conditions and cancer. PSA testing only serves as a screening means to indicate if a prostate problem exists. The doctor takes the PSA test results into account, along with other factors, before deciding if additional testing is required.

Prostate PSA Levels – What Do They Indicate?

PSA is measured in terms of nanograms per milliliter, or ng/ml. A PSA of 4 to 10 ng/ml is considered slightly elevated, 10 to 20 is moderately elevated, and above 20 is highly elevated.

One high PSA reading does not necessarily require more tests. This is because certain factors can cause PSA levels to rise or fall. For example, bed rest may lead to a drop in PSA levels, while cycling may lead to a rise in PSA levels. Before having a PSA test, you may want to refrain from sexual activity for 1 to 2 days. If you have had a cystoscopy, schedule your PSA test only several weeks after your cystoscopy.

If your PSA level is slightly elevated, your doctor may choose to monitor your PSA levels to determine if they continue to rise over time. If levels continue to rise, he or she may suggest more extensive tests.

PSA test results alone is not sufficient to determine if a man has prostate cancer. Most men with abnormal PSA levels are not diagnosed with cancer. Only 25 to 30 percent of men with PSA levels higher than 4 ng/ml will be biopsied and diagnosed with cancer. 15 in 100 men over 50 will have elevated PSA levels but only 3 of these will have prostate cancer. Conversely, there are men with extremely low PSA levels who had biopsies showing cancer there is a way to treat erectile dysfunction with cialis.

Because of this, doctors generally recommend the use of the digital rectal examination (DRE) as well as the  PSA test to detect prostate cancer.


The most effective weight lifting methods

When it comes to lifting weights, it is important that you know how to lift correctly in order to gain maximum muscle gains. You may already know that the more muscle your body has, the more calories it must burn just to stay stable and upright. More calories being burned means an easier task of burning stubborn belly fat and losing weight.

As i stated in a previous post, muscle building is an adaption process which is carried out by the muscles so that they can learn to cope with the excessive stress and strain that they have to deal with. After a while, muscle building gains slow down to the body becoming used to the excessive strain on the muscles. In order to combat adaption, it is important that you vary your workout to promote maximum muscle fiber tear.

Lift Correctly

During weight lifting, it is essential that you lift the weights correctly in order to promote maximum fiber tear and muscle mass gains. In order to complete a proper weight lifting “rep”, you must fully extend and fully contract the muscle. For example during a bicep curl, you must fully extend the bicep so that the arm is straight, and then fully contract the bicep so that the weight nearly touches your face. I see so many people in the gym completing “half reps” as such just so they can prove how much weight they can lift. It is not necessary to prove how much weight you can lift and you will be much better off if you lift a weight which you can perform a full rep with. Performing full reps ensures that the entire muscle is hit and all of the fibers are torn, resulting in maximum muscle mass gains.

As you can see from the image, the shoulders are fully extended and contracted in order to hit the entire deltoid muscle and promote maximum fiber tear.

There are a number of different methods which you can use to combat the adaption process and promote maximum muscle mass gains.

Slow Reps

Slow reps can be extremely beneficial at for combating adaption as they promote extra fiber tear due to the slow movement of the weight. Performing slow reps can be very painful but they are completely worth it as it ensures that the muscles are hit deeply. When performing slow reps, always ensure that you perform a “complete rep” making sure that you fully extend and contract the muscle you are aiming to build.

Adult, Body, Close-Up, Exercise, Fit, Fitness, Girl

Shortend rest between sets – Shortening the amount of time you rest in between each set can be beneficial for combating adaption as it gives your muscles a more complete and thorough workout. While you rest in between each set, the muscles refuel themselves with glycogen which also toughens the fibers and makes them more difficult to tear. Taking shorter rest between sets means that the muscles will not be fully replenished with glycogen and will be easier to tear. If you take a 1 minute break in between each set, try taking only 30 seconds break in between each set in order to promote maximum fiber tear.


Signs And Symptoms Of Prostate Cancer

What Are The Signs And Symptoms Of Prostate Cancer?

This blogpost explores the potential prostate cancer signs and symptoms that men may experience before prostate cancer is diagnosed. Seeing a doctor and arranging for prostate cancer screening when one experiences these symptoms will help save lives.

The Warning Signs Of Prostate Cancer

1) Weak Urination Or Inability To Urinate

As the prostate surrounds the urethra, obstructive urinary symptoms may mean prostate trouble. Having a weak urinary system, failing to empty the bladder, being unable to urinate, straining, waiting too long to start urinating or having the urine stream stop and start during urination are potential prostate cancer warning signs.

These symptoms may also indicate the occurrence of benign prostatic hyperplasia (BPH), the overgrowth of normal prostate cells which is not cancerous. BPH usually grows along the urethra (causing urinary symptoms) in what is called the transition zone. 80 percent of prostate cancer grow in the outer part of the prostate (the peripheral zone) and do not cause urinary symptoms.

2) Painful Or Frequent Urination

Frequent urination, an urgent need to urinate, and painful urination may also be physical symptoms of prostate cancer. However, they are also more likely to indicate an infection of the prostate or urinary tract.

Benign enlargement of the prostate, bladder cancer, or some other irritation in the bladder, such as a bladder stone, may also cause these symptoms.

3) Inability To Urinate Or Kidney Failure

If severe symptoms such as an inability to urinate and kidney failure are due to prostate cancer and not to BPH, the prostate cancer is typically larger and more likely to have spread locally or elsewhere.

Spread into the base of the bladder may have blocked the ureters that carry urine from the kidneys to the bladder. Or it may block the urethra where it courses through the prostate.

4) Blood In Urine

Blood in the urine may be caused by conditions other than prostate cancer. However, if prostate cancer is present, blood in the urine may signal that caner has spread to the urethra or bladder and that the disease is relatively advanced.

5) Erectile Dysfunction

Some men may be unable to have and maintain an erection. This will prompt your doctor to screen for prostate cancer although the erectile dysfunction may be unrelated to cancer. Some people take a drug called Cialis to have an erection although you should be careful of Cialis side effects if you have heart disease. If prostate cancer is present, erectile dysfunction could be due the invasion of the nearby nerves, that normally help a man achieve erections, by the cancer.

In rare cases, aggressive local spread of prostate cancer may also cause a prolonged painful erection known as priapism.

6) Blood In Semen

Blood in ejaculated semen is most commonly associated with prostatitis, an inflammatory conditions of the prostate. In men over the age of 55, this may occasionally be a sign that prostate cancer is present.

7) Abdominal Pain Or Digestive Symptoms

Locally advanced prostate cancer can invade or surround the rectum and produce obstructive symptoms similar to colorectal cancer symptoms, although this is rare.

A tough tissue separates the prostate from the rectum and tends to serve as a barrier to prevent prostate cancer from invading the rectum directly. When the invasion does happen, it may cause constipation, abdominal pain and cramping, rectal pain, bleeding or intermittent diarrhea.

 Weight Loss, Fatigue, Or Generalized Weakness

As cancer advances, it metastasizes to other sites in the body. Five percent of prostate cancer cases are sometimes diagnosed because of the signs and symptoms of metastasis.

General symptoms of any advanced or metastasized cancer of any kind, as well as symptoms of metastasized prostate cancer, would include weight and appetite loss, tiredness and weakness.

9) Back Or Pelvic Pain

Back or pelvic pain are common symptoms of prostate cancer and a host of other different conditions. However, unrelenting pain in the back or pelvic region is one of the common signs and symptoms of advanced prostate cancer.

This is because prostate cancer typically first spreads to the bones, specifically the pelvis and spine. Besides low back pain, bone pain in other areas is also possible, as prostate cancer can also spread to the ribs and bones in the extremities.

In some cases, a broken bone is the first sign of bone metastasis. Fractures, especially in hip bones that have been weakened by cancer, cause pelvic pain.

10) Pain, Numbness Or Weakness In The Legs

Extensive metastases in the spine can compress the nerves in or near the spinal cord and cause pain, numbness, or weakness in the lower extremities, problems with bowel or urinary control, or even paralysis.

Nerves in or near the lower part of the spinal cord affect the legs, bladder, and intestines, which is why compression of the spinal cord can cause these problems. 

11) Clotting Disorder

On rare occasions, men with advanced prostate cancer experience severe bleeding, usually from multiple sites. Release of substances from the prostate cancer into the bloodstream is believed to cause both clotting in the body as well as destruction of a substance necessary for clotting. As a result, the normal clotting process which normally prevents excessive bleeding is affected.

12) Mental Changes And Other Symptoms

Prostate cancer invading the bones can force large amounts of calcium out of the bones and into the bloodstream. Higher-than-normal levels of calcium in the blood (also known as hypercalcemia) can cause mental changes, nausea, vomiting, and abdominal pain.

How To Tell If Urinary Symptoms May Be Due To Prostate Cancer, And Not BPH

Symptoms due to prostate cancer may appear more suddenly over a matter of months. Urinary symptoms due to benign enlargement of the prostate tend to progress slowly over the years.

Younger men who have obstructive or irritative urinary symptoms should be evaluated for prostate cancer. This is because BPH usually appears after age 60. Several studies have also suggested that African-American men more often have obstructive symptoms at a younger age.

As benign prostatic hyperplasia (BPH) and prostate cancer share the same symptoms, be as specific as you can when you describe your symptoms to your doctor.
