What is Cancer?

Cancer refers to any one of a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissue. Cancer also 
has the ability to spread throughout your body. 
Cancer is the second-leading cause of death in the United States. But survival rates are improving for many 
types of cancer, thanks to improvements in cancer screening and cancer treatment.

Prostate cancer is cancer that starts in the prostate gland (cancer of the prostate gland). 
The prostate is a small, walnut-sized structure that makes up part of a man's reproductive system. 
It wraps around the urethra, the tube that carries urine out of the body.

What is prostate gland?
Only men have prostate gland and it is part of the male genital system. It feels like a rubbery mass on rectal examination and is like the size of a large marble. The prostate gland lies on the floor of the pelvis and positions itself between the penis and the bladder.

Prostate cancer is a disease which only affects men. 
Cancer begins to grow in the prostate - a gland in the male reproductive system.  The word "prostate" comes from Medieval Latin prostate and Medieval French prostate. The ancient Greek word prostatesmeans "one standing in front", from proistanai meaning "set before". The prostate is so called because of its position - it is at the base of the bladder.

The prostate is a gland found only in males. It is located in front of the rectum and below the urinary bladder. The size of the prostate varies with age. In younger men, it is about the size of a walnut, but it can be much larger in older men. The prostate's job is to make some of the fluid that protects and nourishes sperm cells in semen, making the semen more liquid. Just behind the prostate are glands called seminal vesicles that make most of the fluid for semen. Theurethra, which is the tube that carries urine and semen out of the body through the penis, goes through the center of the prostate...read more>>

During a digital rectal exam a physician feels the prostate—a small gland that produces seminal fluid—for abnormalities. Annual DRE screenings for males over the age of 50 helps to indicate the sign of prostate cancer.

Prostate Cancer Prevention
You can reduce your risk of prostate cancer if you:
Choose a healthy diet full of fruits and vegetables.
Choose healthy foods over supplements.
Exercise most days of the week.
Maintain a healthy weight.
Talk to your doctor about increased risk of prostate cancer.

Take note that sex is good for you in ways you may never imagined
and that the health benefits extend well beyond the bedroom.


Prostate Cancer
Symptoms, diagnosis and treatment
Prostate gland is an organ of the male reproductive system. It secretes a thick whitish fluid that helps trans­port sperm. All male mammals have some form of pros­tate gland. In men, the prostate is just below the urinary bladder and directly in front of the rectum. It weighs about 20 grams and is about the size of a chestnut. The prostate consists of muscular and glandular tissue and has a tough, fibrous surface.

Sperm is produced in the testicles and travels through two tubes to the prostate. There, the tubes con­nect with the urethra, the channel through which urine flows from the bladder and out of the body. The fluid se­creted by the prostate mixes with the sperm. This fluid nourishes the sperm and helps transport it from the body through the urethra.

Abnormal enlargement of the prostate, a condition called hyperplasia of the prostate or benign enlarge­ment of the prostate, is common among men over 50 years of age. An enlarged prostate can press on the ure­thra. Such pressure can make the passing of urine from the body difficult and may result in bladder infection or kidney damage. In many cases, treatment includes the surgical removal of part or all of the prostate.

Cancer of the prostate may also strike older men. In most cases, it spreads from the prostate to other parts of the body before being detected. The cancer is stimu­lated by the male hormone testosterone, which is pro­duced by the testicles. If the cancer has spread widely, doctors treat it with female hormones or by castration (removing the testicles surgically). If the cancer has not spread beyond the prostate, the diseased tissue is re­moved. See also Reproduction (diagram: Human reproduc­tion).


Prostate cancer prevention
You can reduce your risk of prostate cancer if you:
Choose a healthy diet full of fruits and vegetables. Avoid high-fat foods and instead focus on choosing a variety of fruits, vegetables and whole grains. Fruits and vegetables contain many vitamins and nutrients that can contribute to your health. One nutrient that is consistently linked to prostate cancer prevention is lycopene, which can be found in raw or cooked tomatoes.
Whether you can prevent prostate cancer through diet has yet to be conclusively proved. But eating a healthy diet with a variety of fruits and vegetables can improve your overall health.

Choose healthy foods over supplements. No studies have shown that supplements play a role in reducing your risk of prostate cancer. While there has been some interest in vitamins and minerals, such as vitamin E and selenium, to lower prostate cancer risk, studies haven't found a benefit to taking supplements to create high levels of these nutrients in your body. Instead, choose foods that are rich in vitamins and minerals so that you can maintain healthy levels of vitamins in your body.

Exercise most days of the week. Exercise improves your overall health, helps you maintain your weight and improves your mood. There is some evidence that the men who get the most exercise have a lower incidence of prostate cancer when compared with men who get little or no exercise.

Try to exercise most days of the week. If you're new to exercise, start slow and work your way up to more exercise time each day.

Maintain a healthy weight. If your current weight is healthy, work to maintain it by exercising most days of the week. If you need to lose weight, add more exercise and reduce the number of calories you eat each day. Ask your doctor for help creating a plan for healthy weight loss.

Talk to your doctor about increased risk of prostate cancer. Men with a high risk of prostate cancer may consider medications or other treatments to reduce their risk. Some studies suggest that taking 5-alpha reductase inhibitors, including finasteride (Propecia, Proscar) and dutasteride (Avodart), may reduce the overall risk of developing prostate cancer. These drugs are used to control prostate gland enlargement and hair loss in men.


However, some evidence indicates that men taking these medications may have an increased risk of getting a more serious form of prostate cancer (high-grade prostate cancer). If you're concerned about your risk of developing prostate cancer, talk with your doctor.


What does the prostate gland do?
It secrets a protein-like mixture rich in albumin for the sperms to live on and it also acts as a transport medium for the sperms. Semen is a mixture of sperms and a collection of fluids secreted by the seminal vesicles, bulbo-urethral glands and the prostate gland.

Cancer of the Prostate Gland
It is the most common cancer in men worldwide (21%), followed by lung cancer (19%) and bowel cancer (15%). Every year it is the second most common cause of cancer death in men (12%) behind lung cancer (34%) and ahead of bowel cancer (11%). Treatment depends on the staging of the cancer and may comprise a combination of surgery, radiotherapy and hormone therapy.

Screening and early detection of prostate cancer
There is a protein in the blood called Prostate Specific Antigen, PSA. It is produced by cells in the prostate gland and is thought to play a role in preventing semen form coagulating.

According to certain researchs, 60% of men with early stage prostate cancer already have an elevated PSA level above the highest value found in the normal population             (4 ng/mL). Therefore, the blood test of PSA can be used to screen for the presence of this cancer.

PSA levels usually begin to rise 2-3 years before prostate cancer begin to invade the surrounding tissue. Therefore annual tests allow early detection of most cancers while it's still confined within the prostate gland.

Infection and benign enlargement of the prostate may also cause elevated PSA levels in the blood. The level of PSA in benign hypertrophy of the prostate is relatively stable or rise slowly. The PSA level in prostate cancer is 10 times higher for any given gland size that when no cancer is present.

The symptoms of prostatitis will be recognised by your doctor and the PSA levels will fall to normal after treatment.

Take note
A few men with prostate cancer may have normal PSA levels. Thus, the test should be used in combination with rectal examination and rectal ultrasound examination.

Monitoring of prostate cancer
PSA and Prostatic Acid Phosphatase blood levels may be used to monitor the treatment of prostate cancer.

A fall in both markers suggest a good response to treatment. A stable level shows control has been achieved. Rising levels will detect recurrence after treatment. However, a small proportion (10%) of usually advanced cancer will stop producing PSA. The standard marker Acid Phosphatase is then available for assessment.

Prostate enlargement
Married men experience prostate enlargement more than single men.
A history of prostate enlargement in your family also increases the odds that you too will experience the problem.

Protecting your prostate
The prostate gland is located just below a male's bladder and surrounds the top portion of the tube that drains urine from the bladder (urethra). The gland's primary function is to produce most of the fluids in semen, the fluid that nourishes and transports sperm.

Causes
As you get older the male hormone testosterone is converted to a metabolic byproduct called dihydrotestosterone. This reaction is facilitated by an enzyme called 5-alpha reductase.

Dihydrotestosterone is proposed as one of the causes of prostate enlargement.
Diagnosis of enlarged prostate Test may include:
Digital rectal exam: To feel for prostate enlargement.
Urine test: To eliminate other diseases with similar symptoms.
Blood Test: To detect high levels of PSA (prostate specific antigen)
Ultrasound: To estimate the size of your prostate gland.

Signs and symptoms
Only about half the men with prostate enlargement experience signs and symptoms that become noticeable. These signs and symptoms may include:
Weak urine stream
Urgent need to urinate
Difficulty starting urination        
Not being able to completely empty the bladder
Dribbling at the end of urination           
Blood in the urine (hematuria)
Frequent need to urinate 
Urinary tract infection
Increased frequency of urination at night (nocturia)


Avoid
A lifestyle high in saturated fat such as meat, milk and butter, excessive alcohol consumption and stress.
Increase
The consumption of soy products, pumpkin seeds and the lignans found in flaxseed oil. Zinc found in oysters, sunflower seeds and wholegrains has been shown to inhibit the activity of 5-alpha reductase.

Alternative Medicine
Extract from the berries of Saw Palmetto has been studied in large about its effect on reducing the activitiy of 5-alpha reductase and inhibit prostate tissue growth.

Making some lifestyle changes can often help to control the activity of 5-alpha reductase and inhibit enlargement of the prostate.
