Common Prostate Cancer Symptoms

Early prostate cancer usually causes no symptoms. Sometimes, however, prostate cancer does cause symptoms, often similar to those of diseases such as benign prostatic hyperplasia. Prostate symptoms (sintomas prostata) may include; trouble starting and stopping while voiding, burning during urination, frequent urination, urinary retention, and blood in urine both microscopic hematuria and gross hematuria (sangre orina).

   Prostate cancer is associated with urinary dysfunction as the prostate gland surrounds the prostatic urethra. Changes within the gland, therefore, directly affect urinary function. Because the vas deferens deposits seminal fluid into the prostatic urethra, and secretions from the prostate gland itself are included in semen content, prostate cancer may also cause problems with sexual function and performance, such as difficulty achieving erection or painful ejaculation.
   As the prostate enlarges due to cancer or another problem, the urethra is pinched tighter and tighter within the prostate. As the tube narrows, urine has a much harder time making its way through the urethra and out of the body.
   This results in four primary urinary symptoms:
       Frequency - urinating much more often than normal.

       Urgency - having a sensation that you need to urinate immediately.

       Nocturia - getting up to urinate multiple times during the night.

       Hesitancy - difficulty starting the urine stream.
   All of these symptoms are a direct result of the urethra being pinched closed by the enlarged prostate.
   The urinary symptoms discussed above are undoubtedly the most common symptoms experienced by men with prostate cancer. However, they are not the only ones. Other less common symptoms include:
       Blood in the urine.

       Blood in the semen.

       New-onset erectile dysfunction (impotence).

       Bone pain (especially in the lower back, hips, or ribs).

       Loss of bladder control.
   These symptoms are less specific to problems with the prostate (meaning that problems with other organs such as the bladder can also cause them). However, they are important symptoms of which to be aware.
   Prostate cancer when first diagnosed is categorized by the extent to which the prostate cancer has reached. This is called staging and there are four stages.
   Prostate cancer stage I is microscopic in size and it cannot be felt by the doctor in a digital rectal exam.

   Prostate cancer stage II can be felt by the doctor as a lump in the prostate but is still contained inside of the prostate.

   Prostate cancer stage III has spread out past the prostate into tissue that is close to the prostate such as the seminal vesicles.

   Prostate cancer stage IV has metastasized into other organs such as the lymph nodes, bones, and lungs.
   Men can look to their risk factors that may increase their chance of getting prostate cancer which may give them reasons to make sure they get their medical checkups. The risk factors include: age, since men over 65 years old are the bulk of prostate cancer patients. The age for prostate cancer screening which means getting a digital rectal exam and PSA tests  ranges from 40 years old (if you have risk factors) to getting the prostate cancer screening every 2 years in men from 50 to 69 years old. Black men have both a higher risk of getting prostate cancer and they also have mortality rates that are 3 times higher than Caucasian men. Prostate cancer screening should start at 40 years of age.

What is Prostate Cancer

    The prostate is the male sex gland responsible for the production of semen.
It is located above the rectum and below the urinary bladder. The prostate surrounds the urethra, the tube that carries urine from the bladder to the penis as a kind of "float" at the point where the urethra connects the bladder.

    The function of the prostate is to secrete a slightly acidic fluid, milky or white in appearance, that usually constitutes 50–75% of the volume of the semen along with spermatozoa and seminal vesicle fluid. Semen is made alkaline overall with the secretions from the other contributing glands, including, at least, the seminal vesicle fluid. The alkalinity of semen helps neutralize the acidity of the vaginal tract, prolonging the lifespan of sperm.
    Prostate cancer is one of the most common cancers to occur in men,  after skin cancer.
Prostate cancer may cause pain, difficulty in urinating, problems during sexual intercourse, or erectile dysfunction. Other symptoms can potentially develop during later stages of the disease.
    Rates of detection of prostate cancers vary widely across the world, with South and East Asia detecting less frequently than in Europe, and especially the United States.

    Globally it is the sixth leading cause of cancer-related death in men (in the United States it is the second). Prostate cancer is most common in the developed world with increasing rates in the developing world. Many factors, including genetics and diet, have been implicated in the development of prostate cancer.
    As with many types of cancer, early detection and treatment increase the prospects of cure. In addition, prostate cancer is a type of cancer that grows slowly. When developing the very end of life, as is often the case, the impact of the disease may be minimal.
